Iran won't be invading anyone, whether or not it gets nuclear missiles. One false move by them involving firing a missile and the US air force would blast Iran's military and nuclear facilities to dust. Its air force and navy would not survive beyond 72 hours. The US and NATO are not going to sit back and watch Iran establish some military hegemony over M-E oil or the Gulf region. The main people talking up the Iran threat up are the Israeli government. Israel is used to being the only nuclear power in the region, which it thinks makes it an important world player. Actually the reverse is true, it begs the question why Israel (7 million) should have nukes and not sign the NPT, while a nation of 70 million can not. It is worrying that Jewish lobbies are trying to lead the world in the direction of pre-emptive strikes on Iran so that Israel can remain the sole regional nuclear power. Fortunately, wiser heads seem to be prevailing so far and Israel and its war is parked in the wings.
