Btw, the Arabs/Muslims did try it, 1967, got their butts handed to them when Israel figured out no amount of talking was going to stop it and instead launched a surprise offensive. As a result, Israel unified Jerusalem, and took control of the Sinai Peninsula, Golan Heights, West Bank and the Gaza Strip. Except for Jerusalem, Israel has been obligated to return those areas in return for peace with it's neighbors. Funny, Israel's only real requirement is to be recognised by the people there and have peace with them, in over 40 years of occupation, the Palestinians haven't been able to do that. Israel gave a limited self-government, the Palestinians elected former Terrorist, when they didn't attack Israel and want to recognise it and have peace, the Palestinians then elected a more extremist faction that still tries to carry out attacks against Israel, including a very large number of rockets shot at Israeli civilian targets.
Iran, Iraq, Syria and other countries have been supporting the PLO and other terrorist organizations constantly attacking Israel throughout it's history. One of the big issues about the whole Iran Nuclear thing is the fact they have sworn to destroy Israel and some believe it because of the continuous sponsorship of terrorist and attacks against Israel. I do believe they will attack someone, just not for sure who. Israel, the US or Sunni Muslim countries. Iran has been the largest supporter of insurgents in Iraq (not Al Queda as some want us to believe, Iran and Al Queda actually hate each other, the whole Shia-Sunni thing again), Syria was the other large supporter. During the whole Iraq debacle, Sunni's and Shi'ites actually seemed more interested in killing each other than Americans and generally only went after Americans when we tried to stop them killing each other or were otherwise in the way. Iran is a serious threat to Afghanistan, not in Afghan, but to. They don't support the Taliban or Al Queda and if we pull out, Iran is a prime suspect of who will gain control there, them or the Taliban. Sucks either way for us.
