You guys are just insane if you think Iran would have any chance against the US. Do you guys not remember during the first golf war, Iraq had one of the largest militaries in the world and it was destroyed no problem by the US forces. Not only did they destroy the military, the Iraqi forces where to scared to even get in their planes to fight the US because they were getting blown out of the sky the second they would take off. The US would not even need to place troops in Iran, they would be dropping 100k bombs on this country during an opening attack. The country would be nothing.
It is a surprise that Iran is still around right now, they have caused so many problems with the war in Iraq. They have kidnapped British soldiers, they have supplied weapons to insurgents and provide traning fro fighters going to attack US bases in Iraq. Not only that they have came within short distances of US boats in the Mideast waters. The order to kill the boats was given just seconds after the boats left the waters.
Iran is also causing problems with Israel, saying that the holocaust never happened and threatening to wipe every Jewish person from the face of the planet.
Israel has also been forced to protect herself from these enemies and each time they have destroyed the military of these foreign nations. Also due to these middle east countries attacking Israel they have almost started a third WW. When they go crying to the USSR back in the day, because Israel beat the shit out of them.
