I'll tell you the same thing I tell Chaim: Israel's Bolshevik establishment doesn't work in a vacuum. It gets away with murder (literally) because it has brainwashed most Israelis to go along with, or at least tolerate, it.
I guarantee you that if the Saudi regime pardoned a Jewish militant who snuck into the country and killed an Arab Nazi family, that they would be ovrerthrown by the public that same day, no matter how many die in the process.
