It was the plight of Jews consigned to Displaced Persons camps in Europe that both moved and outraged President Harry Truman, who supported Jewish immigration to Palestine and, when the time came, the new state itself. Something had to be done for the Jews of Europe. They were still being murdered.
On May 12, [1948,] Truman held a meeting in the Oval Office to decide the issue. Marshall and his universally respected deputy, Robert Lovett, made the case for delaying recognition -- and "delay" really meant "deny." Truman asked his young aide, Clark Clifford, to present the case for immediate recognition. When Clifford finished, Marshall, uncharacteristically, exploded. "I don't even know why Clifford is here. He is a domestic adviser, and this is a foreign policy matter. The only reason Clifford is here is that he is pressing a political consideration."
Marshall then uttered what Clifford would later call "the most remarkable threat I ever heard anyone make directly to a President." In an unusual top-secret memorandum Marshall wrote for the historical files after the meeting, the great general recorded his own words: "I said bluntly that if the President were to follow Mr. Clifford's advice and if in the elections I were to vote, I would vote against the President."
