Britain controlled Palestine after WW2
Britain controlled Palestine from the end of World War I until February 1947 when, in response to Zionist terrorist attacks, Britain handed Palestine over to the United Nations to solve the Palestinian problem.
Palestine
Syria is independent, but is in a state of civil war. Palestine is quasi-independent because of the Israeli Occupation of the West Bank and the non-recognition of Hamas-controlled Gaza by most countries around the world.
Nothing, as the question is written. Syria, Palestine, and Iraq were mandates/proto-states that were carved out of the Ottoman-controlled Middle East as a result of Sykes-Picot Agreement during World War I and were only realized in the Treaty of Versailles after World War I. As as a result, there was nothing to promise non-existent entities. What the question is likely intending to ask is "What was promised to the Arabs concerning the regions that would become Syria, Palestine, and Iraq during World War I?" -- If that is the case, please see the Related Link below.

A lot of different reasons. One big one is that the British, who controlled what was then Palestine, passed a law shortly before the war began that kept Jews from moving there.
In 1945, Palestine remained a British Mandate (United Kingdom).
Syria was under the mandate of France after W 1.
