It's because Jews are easy pickings. The problem is that Jews have, as a group, a 'victim' mentality. For whatever reason, they refuse to fight or do whatever is necessary to stop the various bullies of the world from picking on them.
They think they can just turn the other cheek. But, a man has only two cheeks.
Perhaps but the military organizations assembled by Israel since 1947 are, in my view, among the best, if not the best, in the world....These certainly have not turned the "other cheek" to actual or perceived assault.
As ex military myself, I would like to see our civilian air transportation industry emulate them in things such as their use of profiling for the traveling public as it has proven a tremndopus success...head and shoulders above the Norm Mineta mess we have here in the U.S.
