In an article in Tablet in early March, Lee Smith showed how Barack Obama’s degrading of America’s alliance with Israel and his wooing of Iran were motivated essentially by a plan to transform the Democrat Party. To that end, foreign policy was subordinated. The party of Truman, the three Kennedy brothers, and Skip Jackson had consistently moved American policy towards a strong alliance with Israel out of a basic sympathy with its cause and with that of the Jewish people still suffering persecution around the world (think of Jackson’s powerful support of the cause of Soviet Jewry).
Truman’s choice to recognize immediately the newborn state of Israel was a decision that came from his deepest sense of right. He overrode not only his State Department functionaries, whom he dismissed as the “striped-pants boys,” but also the man he respected above all others in government — George Marshall.
Marshall was the architect of victory in World War II and the visionary savior of the freedom of western Europe after the war. His opposition to Jewish statehood was his anticipation that the fledgling Jewish state would not stand a chance against the combined forces of all the Arab states united against them. He foresaw the bloodbath and desolation that so many in the Arab world boasted would happen and did not want to see the Holocaust continued. He staked his career on this, for the best of reasons, saying to not follow his advice would lead to his resignation. Indeed it did, though Marshall waited to leave so as not to embarrass his boss or discredit the government of the country he served so well and so selflessly.
What was true for Truman became mainstream when, gradually, the magnitude of the evil of anti-Semitism was revealed in its utter horror as the Holocaust sank into civilization’s consciousness. It was not a question of left or right, but of basic moral sobriety and plain human decency, that the kind of ideology and government that thrives on such hatred must be opposed, whether it is Hitlerism, Stalinism, or Khomeinism.
This was firmly established in the power structure of the Democrat Party, where so many Jews felt at home. And, Smith points out, this is what Obama came to transform radically.
