During the 1920s and 30s, America refused asylum to many millions of Jews fleeing persecution in the pogroms and later under the Nazis.
Official government reports labelled Jews 'feeble-minded', 'anarchists' etc; well the upshot was the 1924 Immigration Act which enabled the Nazis to kill their six million.
America only supports Israel today because Israel is in reality run on secular principles and it is an ally in the U.S. plan for world domination. A genuinely religious Israel would probably lose its support from the U.S. which is, in my humble opinion, exactly what evangelicals would like to see. Howbeit, the end of the world is either approaching or humanity as a whole is well and truly doomed.
