The story of the United States decision to recognize Israel is well-documented. Less well known is the fact that someone had to first make a request for recognition and no one in the provisional government had thought to do so.
Clark Clifford, President Harry Truman’s aide, called Eliyahu Epstein, a Jewish Agency official in Washington, and explained that there had to be an official request. Epstein, who was not actually a member of the government, nevertheless drafted a letter and signed it as an “agent of the provisional government.”
Truman’s favorable reply can be found here.
