A copy of the Russian-Turkish agreement negotiated Monday in Sochi by President Vladimir Putin and President Recep Tayyip Erdogan has been released. If its authenticity is confirmed, it will be the first Russian recognition of the partition of Syria that will allow Turkey to regain control of the Ottoman territory in northwestern Syria, lost after the Turkish defeat in World War I. The Treaty of Moscow or Treaty of Fraternity (Turkish: Moskova Antla?mas?, Russian: ?????????? ???????) was an agreement between the Grand National Assembly of Turkey (TBMM) under the leadership of Mustafa Kemal Atatürk and Russia under the leadership of Vladimir Lenin, signed on March 16, 1921.    Neither the Republic of Turkey nor the Soviet Union had been created at the time. The Turkish government, then internationally recognized, was Sultan Mehmed VI, but it was not a party to the Moscow Treaty. At point 2 of the agreement with Erdogan, Putin agreed to end Russian air operations against targets in Idlib and acknowledged that “all necessary measures to avoid military operations and attacks on Idlib” will now mean that Turkish-occupied Idlib is a no-fly zone for the Russian Air Force. Soner Cagaptay, a Turkey expert at the Washington Institute, said the deal “freezes the conflict on the ground.” In Thursday`s deal with Erdogan in the Kremlin, Putin gave in to Turkish calls for a ceasefire, something the Syrian government and its Russian benefactor had previously opposed by continuing an offensive to wipe out the last rebel pockets in Idlib. Unlike Syrian President Assad, who has vowed to recover “every inch of land” from the rebels, Russia is primarily interested in protecting its military bases in Syria and avoiding a major war. .
