At least since January of 2016 Putin began to demand offically and publicly that Syria change her Constitution as part of the Putin-Kerry-Ribbentrop pact

This is how the news about the Russian draft of the Syrian Constitution or even the idea that Putin or the Kremlin would demand that Syria change its constitution have been met by Putinist trolls:

"This is complete bullshit, work of fiction, there's nothing of such a draft between Russia & USA. It will not happen, this is not the agenda. USA & allies are in a militarily losing & fragile situation. They are in no way to influence situation on ground in Syria."

"Why would russia rewrite syrias constituton?as for syrias president being a foreigner..thatd be US innovation"

Ignoring and forgetting all this:

Putin, January 5: "Russian President Vladimir Putin said Syria needs to start working on a new constitution as a first step to finding a political solution to its civil war ... "I believe it's necessary to move toward constitutional reform (in Syria). It's a complicated process, of course. And after that, on the basis of the new constitution, (Syria should) hold early presidential and parliamentary elections", Putin said in the interview which was conducted on Jan. 5." http://www.reuters.com/article/us-mideast-crisis-syria-putin-idUSKCN0UQ09H20160112

RT on March 25, 2016: " Russia’s Sergey Lavrov and the US’ John Kerry agreed to push for a political transition in Syria by having a new draft constitution ready by August. ... The discussions lasted over four hours and involved Russian President Vladimir Putin, Russian Foreign Minister Sergey Lavrov, US Secretary of State John Kerry, and US Ambassador to Russia John F. Tefft. “We agreed on a target schedule for establishing a framework for a political transition [in Syria] and also a draft constitution, both of which we targeted by August,” Kerry told journalists at a joint news conference with Lavrov following the meeting." https://www.rt.com/news/337124-syria-talks-constitution-transition/

BBC, March 24: "The US and Russia have agreed to aim for a draft version of a new constitution for Syria by August, US Secretary of State John Kerry has said. Mr Kerry was speaking after four hours of talks at the Kremlin with Russian President Vladimir Putin." http://www.bbc.com/news/world-middle-east-35897667

Bloomberg reporting in April using Western/US diplomatic sources: "Russia and the U.S are working on drafting a new constitution for Syria, according to three Western and Russian diplomats, in the clearest sign yet of the two powers’ determination to broker a solution to a five-year civil war that has sent a wave of refugees toward Europe. The joint efforts are at an early stage, and Russia’s current proposals are closer to the Syrian government’s position, said one Western diplomat. The two countries are continuing to exchange ideas, a Russian diplomat said. All three envoys spoke on condition of anonymity because the discussions are confidential. The U.S agreed with Russia on a target of August to create a framework for a political transition and a draft constitution for Syria, Secretary of State John Kerry said after talks in the Kremlin on March 24. The United Nations is leading peace talks in Geneva where the government and opposition are negotiating a settlement. ... The pan-Arab newspaper Al Hayat reported on April 1 that Russia gave a proposed draft of a new Syrian constitution to Kerry during his visit to Moscow last month. The U.S. is studying the proposals, which were based on documents by legal experts close to the government, Al Hayat said, citing an unidentified person familiar with the matter. When asked about the comments, Deputy State Department spokesman Mark Toner cited a statement by Kerry two weeks ago saying that the U.S. and Russia had “agreed on a framework schedule for a Syrian-led political transition by August, which would include a new constitution.” Asked about the new constitutional structure for Syria, Russian Foreign Ministry spokeswoman Maria Zakharova told reporters Wednesday that Russia and the U.S. are ready to assist the process by proposing their ideas. “This is about helping the process, but of course it is the Syrian people who must decide.” http://www.bloomberg.com/news/articles/2016-04-07/u-s-russia-said-to-team-up-to-draft-syria-s-new-constitution

https://now.mmedia.me/lb/en/NewsReports/567021-russia-finishes-draft-for-new-syria-constitution-report: BEIRUT – Russia has put the finishing touches on its proposed draft constitution for Syria as part of the stalled peace process being brokered by Washington and Moscow that calls for a new constitution to be put up for a referendum in the fall.

Lebanese daily Al-Akhbar—which has an editorial line supportive of the Bashar al-Assad regime—reported Tuesday morning that Russia’s draft constitution strips Syria's presidency of some of its powers and ensures the rights of ethnic and religious minorities. According to the report, the draft proposes “substantial amendments” to the current constitution, including moving the authority of legislation away from the presidency while granting additional powers to the Council of Ministers, which currently serves at the whims of President Bashar al-Assad. Al-Akhbar reported that the Russian draft also “gives broad powers to local administrations” that in effect would decentralize powers, which appears to be a potential concession aimed to gain the favor of the de-facto autonomous Kurdish cantons of northern Syria that have moved in recent months to create their own federal system. Unlike current Syrian regime laws that stifle the expression of Kurdish expression, the new constitution aims to enshrine the rights of local regions to use “the language of the majority of the population” in addition to the country’s official language of Arabic.

Sectarian and ethnic minorities are also guaranteed legislative representation, according to Al-Akhbar.

The newspaper also claimed that the Russian draft drops the “socialistic and nationalistic” phraseology enshrined in the current constitution, which was approved in a controversial February 2012 referendum held during the early months of the Syrian uprising.

The first article of Moscow’s proposed constitution labels the country as the “Republic of Syria” instead of its current designation as the “Syrian Arab Republic,” while also dropping the present constitution’s oath to “work to achieve social justice and the unity of the Arab nation.”

Instead, the draft calls for a “free economy” and “patriotism,” according to the lengthy article published by the Lebanese newspaper.

Washington and Moscow have labored to kick-start a transition process in war-torn Syria that would follow the approval of a new constitution, which US Secretary of State John Kerry in March voiced hope would be ready by August.

Indirect peace talks between the opposition and regime have fallen apart since, while the Cessation of Hostilities that began in late February look set to completely fall apart as fighting continues to rage across the country.
