America, like Israel, was created by Europeans through a genocide of the indigenous people. White settlers drove the American Indians off their ancestral land. If they fought, they were killed. Indians were confined to a few reservations. No thought was given to the rights of the Indians.
Whites believed that God wanted them to have the land. Until recent years, the Indian genocide was celebrated in Western movies, and never criticized in schools. Just as Indians were considered uncivilized heathens not deserving basic rights; so are the Palestinians. The parallels between the establishment of the American and Israeli states are many. The American genocide and enslavement of African people likewise has been insufficiently recognized, criticized, or corrected.
Racism thrives at a subconscious level in the vast majority of Americans' minds. Americans consider themselves and their country to be especially righteous and blessed by God. The Israeli Jews, of course, consider themselves the 'Chosen People'. The religious bigotry and tribalism inherent in this idea require no comment.
Many fundamentalist Christians are 'Friends of Israel'. They take the Book of Revelations in the New Testament very seriously. They believe that Christ's Second Coming to Earth will be preceded by the re-establishment of the Kingdom of Israel and a war over Israel. All the more reason for Protestants to help establish Israel and remain its 'friend'.
