The Muslims have to blams someone for their failures; and they will NEVER admit or concede to having a flaw.
Islam realizes that they need to blame someone for their troubles - so the most convenient foe is, always has been, and will forever be the Jew.
It seems to be a genetic defect.
This is not historically accurate. Throughout most of its history the attitude of Islam towards the Jews has been much like that of Christianity, contempt rather than hatred.
Christians were much more hated for most of this time by Muslims, as they were strong enough to be formidable enemies. The Jews, without a state and with no military power, were not. They were despised more than hated.
