The reason Israel is on the map is because they are not successful in destroying it, and Israel has an edge over them in preventing their attacks, not because they do not constanty seek to murder all Israelis. Militant Islam surrounds Israel and you can be sure that if Israel ever fell, God forbid, the US would soon experience all the stuff that is targeting Israel. "First the Saturday people, then the Sunday people."
Sheer numbers my friend. If 'Muslims' wanted it gone, it would be. The point is that most Muslims do not agree with this crap. If all Muslims did, you wouldn't have them living peacefully within Israel and serving in the Israeli military.
