Jokowi Minta Ekskavator Terus Keruk Kali Siang dan Malam

JAKARTA, Saco- Indonesia.com — Pemerintah Provinsi DKI terus mengebut pengerukan sejumlah kali kecil di Ibu Kota. Sebanyak 170 ekskavator diterjunkan untuk menormalisasi sejumlah kali itu.

"Kita ingin mengecek kali dan sungai yang ada di Jakarta. Sudah diterjunkan 170 ekskavator. Ada yang kerja siang, ada yang malam," ujar Gubernur DKI Joko Widodo saat mengunjungi Penghubung Sipon, Semanan, Kalideres, Jakarta Barat, Jumat (31/5/2013).

Mantan Wali Kota Surakarta itu mengungkapkan, pihaknya akan menambah sebanyak 15 hingga 20 ekskavator pada Juni 2013 mendatang. Jokowi ingin pengerukan tersebut cepat selesai.

Meski demikian, Jokowi mengakui mendapat kendala dalam penambahan ekskavator. Banyak kali dan sungai yang memiliki ruas sisi yang kecil. Hal itu menyebabkan ekskavator sulit masuk.

"Kalau kanan kiri sudah rumah itu yang kesulitan membuang endapannya. Kesulitan alat berat masuk ke sungai. Jadi tergantung lokasi," ujarnya.

Jokowi menegaskan bahwa Pemprov tidak tebang pilih dalam menangani sejumlah kali dan sungai di Jakarta. Jokowi ingin agar pengerukan kali dan sungai tersebut mengakibatkan air berjalan lancar dan jika hujan, tidak meluap memenuhi permukiman.

Seperti diketahui, proyek pengerukan sungai dan kali di DKI merupakan bagian dari Jakarta Emergency Dredging Initiative (JEDI). Program itu merupakan upaya pengendalian banjir melalui normalisasi sebanyak 13 sungai di DKI Jakarta. Realisasi proyek yang mulai digagas sejak 2008 tersebut dilakukan secara bertahap dan dibagi dalam tujuh paket pengerjaan.

Sesuai rencana, dari tujuh paket, tiga paket dikerjakan Pemprov DKI, dua paket dikerjakan Balai Besar Wilayah Sungai Ciliwung Cisadane (BBWSCC), dan dua lainnya dikerjakan Cipta Karya melalui bantuan dana World Bank. Setelah sempat terpendam, proyek yang tak kunjung dikerjakan oleh gubernur era Foke itu pun dilanjutkan kembali oleh Jokowi.

Native American Actors Work to Overcome a Long-Documented Bias

Late in April, after Native American actors walked off in disgust from the set of Adam Sandler’s latest film, a western sendup that its distributor, Netflix, has defended as being equally offensive to all, a glow of pride spread through several Native American communities.

Tantoo Cardinal, a Canadian indigenous actress who played Black Shawl in “Dances With Wolves,” recalled thinking to herself, “It’s come.” Larry Sellers, who starred as Cloud Dancing in the 1990s television show “Dr. Quinn, Medicine Woman,” thought, “It’s about time.” Jesse Wente, who is Ojibwe and directs film programming at the TIFF Bell Lightbox in Toronto, found himself encouraged and surprised. There are so few film roles for indigenous actors, he said, that walking off the set of a major production showed real mettle.

But what didn’t surprise Mr. Wente was the content of the script. According to the actors who walked off the set, the film, titled “The Ridiculous Six,” included a Native American woman who passes out and is revived after white men douse her with alcohol, and another woman squatting to urinate while lighting a peace pipe. “There’s enough history at this point to have set some expectations around these sort of Hollywood depictions,” Mr. Wente said.

The walkout prompted a rhetorical “What do you expect from an Adam Sandler film?,” and a Netflix spokesman said that in the movie, blacks, Mexicans and whites were lampooned as well. But Native American actors and critics said a broader issue was at stake. While mainstream portrayals of native peoples have, Mr. Wente said, become “incrementally better” over the decades, he and others say, they remain far from accurate and reflect a lack of opportunities for Native American performers. What’s more, as Native Americans hunger for representation on screen, critics say the absence of three-dimensional portrayals has very real off-screen consequences.

“Our people are still healing from historical trauma,” said Loren Anthony, one of the actors who walked out. “Our youth are still trying to figure out who they are, where they fit in this society. Kids are killing themselves. They’re not proud of who they are.” They also don’t, he added, see themselves on prime time television or the big screen. Netflix noted while about five people walked off the “The Ridiculous Six” set, 100 or so Native American actors and extras stayed.

But in interviews, nearly a dozen Native American actors and film industry experts said that Mr. Sandler’s humor perpetuated decades-old negative stereotypes. Mr. Anthony said such depictions helped feed the despondency many Native Americans feel, with deadly results: Native Americans have the highest suicide rate out of all the country’s ethnicities.

The on-screen problem is twofold, Mr. Anthony and others said: There’s a paucity of roles for Native Americans — according to the Screen Actors Guild in 2008 they accounted for 0.3 percent of all on-screen parts (those figures have yet to be updated), compared to about 2 percent of the general population — and Native American actors are often perceived in a narrow way.

In his Peabody Award-winning documentary “Reel Injun,” the Cree filmmaker Neil Diamond explored Hollywood depictions of Native Americans over the years, and found they fell into a few stereotypical categories: the Noble Savage, the Drunk Indian, the Mystic, the Indian Princess, the backward tribal people futilely fighting John Wayne and manifest destiny. While the 1990 film “Dances With Wolves” won praise for depicting Native Americans as fully fleshed out human beings, not all indigenous people embraced it. It was still told, critics said, from the colonialists’ point of view. In an interview, John Trudell, a Santee Sioux writer, actor (“Thunderheart”) and the former chairman of the American Indian Movement, described the film as “a story of two white people.”

“God bless ‘Dances with Wolves,’ ” Michael Horse, who played Deputy Hawk in “Twin Peaks,” said sarcastically. “Even ‘Avatar.’ Someone’s got to come save the tribal people.”

Dan Spilo, a partner at Industry Entertainment who represents Adam Beach, one of today’s most prominent Native American actors, said while typecasting dogs many minorities, it is especially intractable when it comes to Native Americans. Casting directors, he said, rarely cast them as police officers, doctors or lawyers. “There’s the belief that the Native American character should be on reservations or riding a horse,” he said.

“We don’t see ourselves,” Mr. Horse said. “We’re still an antiquated culture to them, and to the rest of the world.”

Ms. Cardinal said she was once turned down for the role of the wife of a child-abusing cop because the filmmakers felt that casting her would somehow be “too political.”

Another sore point is the long run of white actors playing American Indians, among them Burt Lancaster, Rock Hudson, Audrey Hepburn and, more recently, Johnny Depp, whose depiction of Tonto in the 2013 film “Lone Ranger,” was viewed as racist by detractors. There are, of course, exceptions. The former A&E series “Longmire,” which, as it happens, will now be on Netflix, was roundly praised for its depiction of life on a Northern Cheyenne reservation, with Lou Diamond Phillips, who is of Cherokee descent, playing a Northern Cheyenne man.

Others also point to the success of Mr. Beach, who played a Mohawk detective in “Law & Order: Special Victims Unit” and landed a starring role in the forthcoming D C Comics picture “Suicide Squad.” Mr. Beach said he had come across insulting scripts backed by people who don’t see anything wrong with them.

“I’d rather starve than do something that is offensive to my ancestral roots,” Mr. Beach said. “But I think there will always be attempts to drawn on the weakness of native people’s struggles. The savage Indian will always be the savage Indian. The white man will always be smarter and more cunning. The cavalry will always win.”

The solution, Mr. Wente, Mr. Trudell and others said, lies in getting more stories written by and starring Native Americans. But Mr. Wente noted that while independent indigenous film has blossomed in the last two decades, mainstream depictions have yet to catch up. “You have to stop expecting for Hollywood to correct it, because there seems to be no ability or desire to correct it,” Mr. Wente said.

There have been calls to boycott Netflix but, writing for Indian Country Today Media Network, which first broke news of the walk off, the filmmaker Brian Young noted that the distributor also offered a number of films by or about Native Americans.

The furor around “The Ridiculous Six” may drive more people to see it. Then one of the questions that Mr. Trudell, echoing others, had about the film will be answered: “Who the hell laughs at this stuff?”

Dean Skelos, Albany Senate Leader, Aided Son at All Costs, U.S. Says

Over the last five years or so, it seemed there was little that Dean G. Skelos, the majority leader of the New York Senate, would not do for his son.

He pressed a powerful real estate executive to provide commissions to his son, a 32-year-old title insurance salesman, according to a federal criminal complaint. He helped get him a job at an environmental company and employed his influence to help the company get government work. He used his office to push natural gas drilling regulations that would have increased his son’s commissions.

He even tried to direct part of a $5.4 billion state budget windfall to fund government contracts that the company was seeking. And when the company was close to securing a storm-water contract from Nassau County, the senator, through an intermediary, pressured the company to pay his son more — or risk having the senator subvert the bid.

The criminal complaint, unsealed on Monday, lays out corruption charges against Senator Skelos and his son, Adam B. Skelos, the latest scandal to seize Albany, and potentially alter its power structure.

The repeated and diverse efforts by Senator Skelos, a Long Island Republican, to use what prosecutors said was his political influence to find work, or at least income, for his son could send both men to federal prison. If they are convicted of all six charges against them, they face up to 20 years in prison for each of four of the six counts and up to 10 years for the remaining two.

Senator Kenneth P. LaValle, of Long Island, who serves as chairman of the Republican conference, emerged from a closed-door meeting Monday night to say that conference members agreed that Mr. Skelos should be benefited the “presumption of innocence,” and would stay in his leadership role.

“The leader has indicated he would like to remain as leader,” said Mr. LaValle, “and he has the support of the conference.” The case against Mr. Skelos and his son grew out of a broader inquiry into political corruption by the United States attorney for the Southern District of New York, Preet Bharara, that has already changed the face of the state capital. It is based in part, according to the six-count complaint, on conversations secretly recorded by one of two cooperating witnesses, and wiretaps on the cellphones of the senator and his son. Those recordings revealed that both men were concerned about electronic surveillance, and illustrated the son’s unsuccessful efforts to thwart it.

Adam Skelos took to using a “burner” phone, the complaint says, and told his father he wanted them to speak through a FaceTime video call in an apparent effort to avoid detection. They also used coded language at times.

At one point, Adam Skelos was recorded telling a Senate staff member of his frustration in not being able to speak openly to his father on the phone, noting that he could not “just send smoke signals or a little pigeon” carrying a message.

The 43-page complaint, sworn out by Paul M. Takla, a special agent for the Federal Bureau of Investigation, outlines a five-year scheme to “monetize” the senator’s official position; it also lays bare the extent to which a father sought to use his position to help his son.

The charges accuse the two men of extorting payments through a real estate developer, Glenwood Management, based on Long Island, and the environmental company, AbTech Industries, in Scottsdale, Ariz., with the expectation that the money paid to Adam Skelos — nearly $220,000 in total — would influence his father’s actions.

Glenwood, one of the state’s most prolific campaign donors, had ties to AbTech through investments in the environmental firm’s parent company by Glenwood’s founding family and a senior executive.

The accusations in the complaint portray Senator Skelos as a man who, when it came to his son, was not shy about twisting arms, even in situations that might give other arm-twisters pause.

Seeking to help his son, Senator Skelos turned to the executive at Glenwood, which develops rental apartments in New York City and has much at stake when it comes to real estate legislation in Albany. The senator urged him to direct business to his son, who sold title insurance.

After much prodding, the executive, Charles C. Dorego, engineered a $20,000 payment to Adam Skelos from a title insurance company even though he did no work for the money. But far more lucrative was a consultant position that Mr. Dorego arranged for Adam Skelos at AbTech, which seeks government contracts to treat storm water. (Mr. Dorego is not identified by name in the complaint, but referred to only as CW-1, for Cooperating Witness 1.)

Senator Skelos appeared to take an active interest in his son’s new line of work. Adam Skelos sent him several drafts of his consulting agreement with AbTech, the complaint says, as well as the final deal that was struck.

“Mazel tov,” his father replied.

Senator Skelos sent relevant news articles to his son, including one about a sewage leak near Albany. When AbTech wanted to seek government contracts after Hurricane Sandy, the senator got on a conference call with his son and an AbTech executive, Bjornulf White, and offered advice. (Like Mr. Dorego, Mr. White is not named in the complaint, but referred to as CW-2.)

The assistance paid off: With the senator’s help, AbTech secured a contract worth up to $12 million from Nassau County, a big break for a struggling small business.

But the money was slow to materialize. The senator expressed impatience with county officials.

Adam Skelos, in a phone call with Mr. White in late December, suggested that his father would seek to punish the county. “I tell you this, the state is not going to do a [expletive] thing for the county,” he said.

Three days later, Senator Skelos pressed his case with the Nassau County executive, Edward P. Mangano, a fellow Republican. “Somebody feels like they’re just getting jerked around the last two years,” the senator said, referring to his son in what the complaint described as “coded language.”

The next day, the senator pursued the matter, as he and Mr. Mangano attended a wake for a slain New York City police officer. Senator Skelos then reassured his son, who called him while he was still at the wake. “All claims that are in will be taken care of,” the senator said.

AbTech’s fortunes appeared to weigh on his son. At one point in January, Adam Skelos told his father that if the company did not succeed, he would “lose the ability to pay for things.”

Making matters worse, in recent months, Senator Skelos and his son appeared to grow wary about who was watching them. In addition to making calls on the burner phone, Adam Skelos said he used the FaceTime video calling “because that doesn’t show up on the phone bill,” as he told Mr. White.

In late February, Adam Skelos arranged a pair of meetings between Mr. White and state senators; AbTech needed to win state legislation that would allow its contract to move beyond its initial stages. But Senator Skelos deemed the plan too risky and caused one of the meetings to be canceled.

In another recorded call, Adam Skelos, promising to be “very, very vague” on the phone, urged his father to allow the meeting. The senator offered a warning. “Right now we are in dangerous times, Adam,” he told him.

A month later, in another phone call that was recorded by the authorities, Adam Skelos complained that his father could not give him “real advice” about AbTech while the two men were speaking over the telephone.

“You can’t talk normally,” he told his father, “because it’s like [expletive] Preet Bharara is listening to every [expletive] phone call. It’s just [expletive] frustrating.”

“It is,” his father agreed.

Ghostly Voices From Thomas Edison’s Dolls Can Now Be Heard

Though Robin and Joan Rolfs owned two rare talking dolls manufactured by Thomas Edison’s phonograph company in 1890, they did not dare play the wax cylinder records tucked inside each one.

The Rolfses, longtime collectors of Edison phonographs, knew that if they turned the cranks on the dolls’ backs, the steel phonograph needle might damage or destroy the grooves of the hollow, ring-shaped cylinder. And so for years, the dolls sat side by side inside a display cabinet, bearers of a message from the dawn of sound recording that nobody could hear.

In 1890, Edison’s dolls were a flop; production lasted only six weeks. Children found them difficult to operate and more scary than cuddly. The recordings inside, which featured snippets of nursery rhymes, wore out quickly.

Yet sound historians say the cylinders were the first entertainment records ever made, and the young girls hired to recite the rhymes were the world’s first recording artists.

Year after year, the Rolfses asked experts if there might be a safe way to play the recordings. Then a government laboratory developed a method to play fragile records without touching them.

The technique relies on a microscope to create images of the grooves in exquisite detail. A computer approximates — with great accuracy — the sounds that would have been created by a needle moving through those grooves.

In 2014, the technology was made available for the first time outside the laboratory.

“The fear all along is that we don’t want to damage these records. We don’t want to put a stylus on them,” said Jerry Fabris, the curator of the Thomas Edison Historical Park in West Orange, N.J. “Now we have the technology to play them safely.”

Last month, the Historical Park posted online three never-before-heard Edison doll recordings, including the two from the Rolfses’ collection. “There are probably more out there, and we’re hoping people will now get them digitized,” Mr. Fabris said.

The technology, which is known as Irene (Image, Reconstruct, Erase Noise, Etc.), was developed by the particle physicist Carl Haber and the engineer Earl Cornell at Lawrence Berkeley. Irene extracts sound from cylinder and disk records. It can also reconstruct audio from recordings so badly damaged they were deemed unplayable.

“We are now hearing sounds from history that I did not expect to hear in my lifetime,” Mr. Fabris said.

The Rolfses said they were not sure what to expect in August when they carefully packed their two Edison doll cylinders, still attached to their motors, and drove from their home in Hortonville, Wis., to the National Document Conservation Center in Andover, Mass. The center had recently acquired Irene technology.

Cylinders carry sound in a spiral groove cut by a phonograph recording needle that vibrates up and down, creating a surface made of tiny hills and valleys. In the Irene set-up, a microscope perched above the shaft takes thousands of high-resolution images of small sections of the grooves.

Stitched together, the images provide a topographic map of the cylinder’s surface, charting changes in depth as small as one five-hundredth the thickness of a human hair. Pitch, volume and timbre are all encoded in the hills and valleys and the speed at which the record is played.

At the conservation center, the preservation specialist Mason Vander Lugt attached one of the cylinders to the end of a rotating shaft. Huddled around a computer screen, the Rolfses first saw the wiggly waveform generated by Irene. Then came the digital audio. The words were at first indistinct, but as Mr. Lugt filtered out more of the noise, the rhyme became clearer.

“That was the Eureka moment,” Mr. Rolfs said.

In 1890, a girl in Edison’s laboratory had recited:

There was a little girl,

And she had a little curl

Right in the middle of her forehead.

When she was good,

She was very, very good.

But when she was bad, she was horrid.

Recently, the conservation center turned up another surprise.

In 2010, the Woody Guthrie Foundation received 18 oversize phonograph disks from an anonymous donor. No one knew if any of the dirt-stained recordings featured Guthrie, but Tiffany Colannino, then the foundation’s archivist, had stored them unplayed until she heard about Irene.

Last fall, the center extracted audio from one of the records, labeled “Jam Session 9” and emailed the digital file to Ms. Colannino.

“I was just sitting in my dining room, and the next thing I know, I’m hearing Woody,” she said. In between solo performances of “Ladies Auxiliary,” “Jesus Christ,” and “Dead or Alive,” Guthrie tells jokes, offers some back story, and makes the audience laugh. “It is quintessential Guthrie,” Ms. Colannino said.

The Rolfses’ dolls are back in the display cabinet in Wisconsin. But with audio stored on several computers, they now have a permanent voice.

Police Rethink Long Tradition on Using Force

WASHINGTON — During a training course on defending against knife attacks, a young Salt Lake City police officer asked a question: “How close can somebody get to me before I’m justified in using deadly force?”

Dennis Tueller, the instructor in that class more than three decades ago, decided to find out. In the fall of 1982, he performed a rudimentary series of tests and concluded that an armed attacker who bolted toward an officer could clear 21 feet in the time it took most officers to draw, aim and fire their weapon.

The next spring, Mr. Tueller published his findings in SWAT magazine and transformed police training in the United States. The “21-foot rule” became dogma. It has been taught in police academies around the country, accepted by courts and cited by officers to justify countless shootings, including recent episodes involving a homeless woodcarver in Seattle and a schizophrenic woman in San Francisco.

With Iran Talks, a Tangled Path to Ending Syria’s War

UNITED NATIONS — Wearing pinstripes and a pince-nez, Staffan de Mistura, the United Nations envoy for Syria, arrived at the Security Council one Tuesday afternoon in February and announced that President Bashar al-Assad had agreed to halt airstrikes over Aleppo. Would the rebels, Mr. de Mistura suggested, agree to halt their shelling?

What he did not announce, but everyone knew by then, was that the Assad government had begun a military offensive to encircle opposition-held enclaves in Aleppo and that fierce fighting was underway. It would take only a few days for rebel leaders, having pushed back Syrian government forces, to outright reject Mr. de Mistura’s proposed freeze in the fighting, dooming the latest diplomatic overture on Syria.

Diplomacy is often about appearing to be doing something until the time is ripe for a deal to be done.

Now, with Mr. Assad’s forces having suffered a string of losses on the battlefield and the United States reaching at least a partial rapprochement with Mr. Assad’s main backer, Iran, Mr. de Mistura is changing course. Starting Monday, he is set to hold a series of closed talks in Geneva with the warring sides and their main supporters. Iran will be among them.

In an interview at United Nations headquarters last week, Mr. de Mistura hinted that the changing circumstances, both military and diplomatic, may have prompted various backers of the war to question how much longer the bloodshed could go on.

“Will that have an impact in accelerating the willingness for a political solution? We need to test it,” he said. “The Geneva consultations may be a good umbrella for testing that. It’s an occasion for asking everyone, including the government, if there is any new way that they are looking at a political solution, as they too claim they want.”

He said he would have a better assessment at the end of June, when he expects to wrap up his consultations. That coincides with the deadline for a final agreement in the Iran nuclear talks.

Whether a nuclear deal with Iran will pave the way for a new opening on peace talks in Syria remains to be seen. Increasingly, though, world leaders are explicitly linking the two, with the European Union’s top diplomat, Federica Mogherini, suggesting last week that a nuclear agreement could spur Tehran to play “a major but positive role in Syria.”

It could hardly come soon enough. Now in its fifth year, the Syrian war has claimed 220,000 lives, prompted an exodus of more than three million refugees and unleashed jihadist groups across the region. “This conflict is producing a question mark in many — where is it leading and whether this can be sustained,” Mr. de Mistura said.

Part Italian, part Swedish, Mr. de Mistura has worked with the United Nations for more than 40 years, but he is more widely known for his dapper style than for any diplomatic coups. Syria is by far the toughest assignment of his career — indeed, two of the organization’s most seasoned diplomats, Lakhdar Brahimi and Kofi Annan, tried to do the job and gave up — and critics have wondered aloud whether Mr. de Mistura is up to the task.

He served as a United Nations envoy in Afghanistan and Iraq, and before that in Lebanon, where a former minister recalled, with some scorn, that he spent many hours sunbathing at a private club in the hills above Beirut. Those who know him say he has a taste for fine suits and can sometimes speak too soon and too much, just as they point to his diplomatic missteps and hyperbole.

They cite, for instance, a news conference in October, when he raised the specter of Srebrenica, where thousands of Muslims were massacred in 1995 during the Balkans war, in warning that the Syrian border town of Kobani could fall to the Islamic State. In February, he was photographed at a party in Damascus, the Syrian capital, celebrating the anniversary of the Iranian revolution just as Syrian forces, aided by Iran, were pummeling rebel-held suburbs of Damascus; critics seized on that as evidence of his coziness with the government.

Mouin Rabbani, who served briefly as the head of Mr. de Mistura’s political affairs unit and has since emerged as one of his most outspoken critics, said Mr. de Mistura did not have the background necessary for the job. “This isn’t someone well known for his political vision or political imagination, and his closest confidants lack the requisite knowledge and experience,” Mr. Rabbani said.

As a deputy foreign minister in the Italian government, Mr. de Mistura was tasked in 2012 with freeing two Italian marines detained in India for shooting at Indian fishermen. He made 19 trips to India, to little effect. One marine was allowed to return to Italy for medical reasons; the other remains in India.

He said he initially turned down the Syria job when the United Nations secretary general approached him last August, only to change his mind the next day, after a sleepless, guilt-ridden night.

Mr. de Mistura compared his role in Syria to that of a doctor faced with a terminally ill patient. His goal in brokering a freeze in the fighting, he said, was to alleviate suffering. He settled on Aleppo as the location for its “fame,” he said, a decision that some questioned, considering that Aleppo was far trickier than the many other lesser-known towns where activists had negotiated temporary local cease-fires.

“Everybody, at least in Europe, are very familiar with the value of Aleppo,” Mr. de Mistura said. “So I was using that as an icebreaker.”

The cease-fire negotiations, to which he had devoted six months, fell apart quickly because of the government’s military offensive in Aleppo the very day of his announcement at the Security Council. Privately, United Nations diplomats said Mr. de Mistura had been manipulated. To this, Mr. de Mistura said only that he was “disappointed and concerned.”

Tarek Fares, a former rebel fighter, said after a recent visit to Aleppo that no Syrian would admit publicly to supporting Mr. de Mistura’s cease-fire proposal. “If anyone said they went to a de Mistura meeting in Gaziantep, they would be arrested,” is how he put it, referring to the Turkish city where negotiations between the two sides were held.

Secretary General Ban Ki-moon remains staunchly behind Mr. de Mistura’s efforts. His defenders point out that he is at the center of one of the world’s toughest diplomatic problems, charged with mediating a conflict in which two of the world’s most powerful nations — Russia, which supports Mr. Assad, and the United States, which has called for his ouster — remain deadlocked.

R. Nicholas Burns, a former State Department official who now teaches at Harvard, credited Mr. de Mistura for trying to negotiate a cease-fire even when the chances of success were exceedingly small — and the chances of a political deal even smaller. For his efforts to work, Professor Burns argued, the world powers will first have to come to an agreement of their own.

“He needs the help of outside powers,” he said. “It starts with backers of Assad. That’s Russia and Iran. De Mistura is there, waiting.”
