The American trusteeship proposal for Palestine, formally known as the United States Proposal for Temporary United Nations Trusteeship for Palestine and announced by President "Harry S. Truman on 25 March 1948, was a revised plan from the "United States government for the future of the "British Mandate for Palestine. The proposal came four months after the approval in the General Assembly of the "United Nations Partition Plan for Palestine which had been vigorously supported by the United States, and represented a major shift in policy in response to the ongoing "1947–1948 Civil War in Mandatory Palestine.
On March 18, the "United Nations Special Committee on Palestine reported that it had been unable to arrange a truce and recommended a temporary trusteeship for Palestine in order to restore peace.
The following day, "United States Ambassador to the United Nations "Warren Austin announced that the United States believes that the partition of Palestine was no longer a viable option. On March 20, "United States Secretary of State "George Marshall confirmed the United States' view that the proposal for a temporary United Nations trusteeship for Palestine is the only idea presently being considered that will allow the United Nations to address the difficult situation in Palestine.
The trusteeship proposal was supported by "Loy W. Henderson, head of the Near Eastern Affairs Bureau, who opposed US support for partition because he believed it would hurt US interests in Arab countries. The proposal was drafted by "Clark Clifford, "White House Counsel and Max Lowenstein.
"The United States has proposed to the Security Council a temporary United Nations trusteeship for Palestine to provide a government to keep the peace. Such trusteeship was proposed only after we had exhausted every effort to find a way to carry out partition by peaceful means. Trusteeship is not proposed as a substitute for the partition plan but as an effort to fill the vacuum soon to be created by the termination of the mandate on May 15. The trusteeship does not prejudice the character of the final political settlement. It would establish the conditions of order which are essential to a peaceful solution."
