Fuck Iran, the worst threat to peace is the Middle East is ISSIL and Israel, and maybe not in that order. In a way, Iran is doing Israel a favor by holding up ISSIL and Al Qaida in Syria. If is wasn't for Hezbollah and Iran, ISSIL would be up Israel' ass by now, so Israel had better hope Assad stays in power.
Israel has been fucking up the Middle East since they started high jacking land and murdering the indigenous population in 1948, and things don't look any brighter for the future. So, unless Israel changes it attitude towards the Palestinian situation, every country surrounding them is going to want them dead. And we are their defenders, which put's a big fat bulls eye on US citizens around the world. You know what was the 1st Arab/Muslim terrorist organization was? The Palestinian Liberation Army, or PLO for short. They invented the high jacking of airplanes and even ships. Why did they start blowing up shit? They simply hated Israel because of the abuse of the Palestinian people. You know what was the main reason that Bin Laden attacked the US? Palestine.
So, until Israel is reigned in, there is ALWAYS going to be the worry of Iran developing a bomb to match the one Israel has.That's why the Iranians hate our guts and want to blow the shit out of Israel, the Palestinians.
So, take one, if not the only one of reasons that Iran would like to incinerate Israel, off of the table, and actually establish a State of Palestine, instead of year after year after year of Israel talking shit, then the US, and actually the whole world could say are you fucking happy now to ALL the Arab nations in the Middle East, and I think they would say yes. That would be nice, wouldn't it? (never going to happen, as long as Republicans exist) Oh, well.
