In recent weeks, Arabs armed with knives and hatchets have struck at dozens of Israelis on the streets of Jerusalem, Tel Aviv, Afula, Beersheba, and elsewhere. Victims include children, women, and elderly men. Imagine how the American public would react to a political group that incited supporters to knife people on the streets of New York, Cleveland, Denver, and Seattle. Fear, indignation, and anger would translate into furious insistence that the government put an end to the evil. No political grievance would be accepted as an excuse for the savagery.
