FDR also was not going to recognize the Jewish State.
On April 5, 1945, Roosevelt wrote to King Abdul Aziz ibn Saud, promising that as long as he was President, America would not recognize a Jewish State:
“I communicated to you the attitude of the American Government toward Palestine...that no decision be taken... I assured you that I would take no action, in my capacity as Chief of the Executive... with regard to the question of Palestine...the policy of this Government...is unchanged.”
He died a week later, and Truman immediately proceeded with plans to recognize the State of Israel.
This is from American Minute with William Federer.
