Excerpt from Introduction of 2014 book, Genesis: Truman, American Jews, and the Origins of the Arab/Israeli Conflict, by John Judis (Sr. Editor at The New Rebuplic) p. 6:
Should American Zionists have been expected to fight tooth and nail for their Jewish brethren overseas? Yes and no. The American Zionist movement was led in its first decades by liberals and progressives like Louis Brandeis, Stephen Wise, Felix Frankfurter, David Dubinsky, and Horace Kallen. Zionism also attracted the enthusiastic support of Christian liberals, including Reinhold Niebuhr, Henry Wallace, and Eleanor Roosevelt, and of the country’s most liberal media, including The Nation, The New Republic, the New York Post (in its earlier incarnation), and the daily PM, which featured I. F. Stone’s journalism.
These liberals and progressives supported labor rights, civil rights, and the first amendment. Wise was a founder of the American Civil Liberties Union and the National Association for the Advancement of Colored People. Many of them had also backed Wilson’s call for the self-determination of colonial peoples. But when it came to Palestine, they were oblivious to the rights of Palestine’s Arabs. In the movement’s first decades, American Zionists averred that the Jews were emigrating to a largely unoccupied wasteland or desert; later, when it became clear that Arabs already lived there, they insisted that these Arabs, who could trace their lineage in Palestine to 638 C.E., could easily pick up and move to Jordan, Iraq, or Syria. After the 1948 wars, they contended that the Palestinian refugees had either fled of their own accord or were induced to flee by Arab leaders. As liberals and progressives, they might have been expected to help Truman fashion a compromise that recognized the rights of Jews and Arabs, but they did nothing of the kind. They excoriated Truman for doing what in any other context they would have condoned and supported. In 1948, Henry Wallace’s Progressive Party targeted Jewish voters unhappy with Truman’s attempts to reach a compromise between Jew and Arab with pamphlets warning that “a vote for Truman is a vote to rebuild Nazi Germany.” 3 These liberals seemed to be willfully ignorant of what was actually going on in Palestine.
