It will be necessary to prevent regional actors from trying to narrow the outlines of a proposal in order to place the external powers against each other and leave the region in chaos. It is therefore essential that the United States, Russia and the EU at least reach a comprehensive understanding and/or agreement. Only then will important regional states such as Egypt, Saudi Arabia, Jordan, Iran and Turkey be introduced. In the third phase, some local players are invited to give their consent. Many sources claim that Sykes-Picot came into conflict with the Hussein-McMahon correspondence of 1915-1916 and that the publication of the agreement in November 1917 led to the resignation of Sir Henry McMahon.  There were several differences, iraq being the most obvious in the British red territory, and less obvious, the idea that British and French advisers would have control of the area designated as an Arab state. Finally, while the correspondence did not mention Palestine, Haifa and Acre should be British and the brown territory (a reduced Palestine) should become internationalized.  The Sykes-Picot Agreement (officially the 1916 agreement on Asia Minor) was a secret agreement between the British government and the French government during World War I on the division of the Ottoman Empire between the Allies. Russia also participated in the talks. On April 21, Faisal headed east. Before leaving, on 17 April Clemenceau sent a draft letter in which the French government stated that it recognized “Syria`s right to independence in the form of a federation of autonomous governments in accordance with the traditions and wishes of the population”, claiming that Fayçal had acknowledged: “that France is qualified as power, Syria needs the help of various advisers to put order and achieve the progress demanded by the Syrian people” and on 20 April, Fayçal assured Clemenceau that he was “deeply impressed by the selfless kindness of your statements to me while I was in Paris, and I must thank you for proposing as the first dispatch of the Interinitive Commission. to identify the wishes of local peoples regarding the future organization of their country.
I am sure the Syrian people will know how to show you their gratitude.  In the Treaties of Sevres (1920) and Lausanne (1923), Turkey renounced all claims of the Ottoman Empire outside the borders of present-day Turkey in favour of Great Britain and France. Britain and France therefore had a legal right to manage these territories. The 1916 agreement did not specify the boundaries of the areas concerned; This was then done by the British and French in a series of agreements that were signed in 1922 and 1923 and which defined the borders of Palestine (including present-day Jordan), Lebanon, Syria and Iraq. Their decision on the borders of the territories was approved by the League of Nations, thus gaining international recognition of legitimacy, while its decision would have been legally binding without the agreement of the League. The spectre of two officials of extra-regional powers, who meet in secret, sharing a region of the world between their own countries and spilling it into international treaties, is now unlikely. However, an initial agreement in principle between the main external players on the reconfiguration of the region will be necessary to allow this change.
