Prior to the centenary of Sykes-Picot in 2016, the media and scientists generated strong interest in the long-term effects of the agreement. The agreement is often cited as “artificial” borders in the Middle East, “without regard to ethnic or sectarian characteristics, which has led to endless conflicts.”  The question of the extent to which Sykes-Picot has really marked the borders of the modern Middle East is controversial.   In the Constantinople Agreement of 18 March 1915, after the start of naval operations ahead of the Gallipoli campaign, Russian Foreign Minister Sergei Sazonov wrote to the French and British ambassadors and claimed Constantinople and the Dardanelles. During a five-week series of diplomatic talks, the United Kingdom and France, although they made their own claims, agreed on greater influence in Iran in the case of the United Kingdom and on the annexation of Syria (including Palestine) and Cilicia for France. The demands of the United Kingdom and France were unanimous and all parties agreed to leave the exact management of the holy sites to a subsequent settlement.  Without the Russian revolutions of 1917, Constantinople and the Strait could have been given after the Allied victory over Russia. This agreement and the Sykes-Picot agreement were complementary, because France and Great Britain had to satisfy Russia first to conclude the partition of the Middle East.  In April 1920, the San Remo Conference distributed Class A warrants on Syria to France and Iraq and Palestine to Britain. The same conference ratified an oil agreement reached at a London conference on 12 February, based on a slightly different version of the Long Berenger agreement, previously signed on 21 December in London. Hussein`s letter of February 18, 1916, McMahon appealed for 50,000 pounds of gold, more weapons, ammunition and food, saying Feisal was waiting for “no less than 100,000 people” to arrive for the planned revolt and McMahon`s response of 10 March 1916 confirming British approval of the applications and concluding the ten letters from correspondents.
In April and May, Sykes discussed the benefits of a meeting in which Picot and the Arabs participated to network each other`s wishes.
