Clarification: the US was not a primary disruptive force in the establishment of the Jewish state either. Typically, the British, Soviets, and Arab states are considered to be more disruptive in terms of turning the tide towards Jewish self-determination. The US played a critical role in helping pass UN General Assembly Resolution 181, the partition plan, but it was never implemented. The US made mostly symbolic moves, as with the endorsement of the Zionist request to grant 100,000 visas to Holocaust survivors and Jewish refugees to enter the British-controlled Mandate of Palestine, but its involvement was mostly limited to a diplomacy based pressure that added to the more powerful moves by other groups and actors.

Your question seemed to imply US involvement was critical in that instance, and I just wanted to clarify that point. Palestinians have often "damned" the British for that early period, and America for later ones.
