Iran wants the enriched Uranium for the purpose of making Nuclear weapons, not nuclear energy. Iran has a large untapped abundance of oil, and coal. both thoses resources would be easier for them and much more cost efficant to produce the required energy. Israel will likely be the ones attack Iran, not the US, the US will however be backing Israel. one of the reason why the President wants the increase in troops in Iraq is to act as a buffer zone between Iran and Israel. Iran will not openly attack US forces, even if the US is indirectly supporting Israel, because Iran does not want the US to have the "moral high ground" if there is a war. Iran also knows that a premptive strike against the US would be a bad thing. The tide against the wars in the middle east would change favorably towards them if Iran attacked first.Ahmadajadine is a very smart man, he may be a nutcase but he does understand the politics on the world stage even more so than guys like Adolph Hitler. He wants to get Iran to be a world power, and he has done a lot of good in that country. But he does know that going toe-to-toe with the US, or even Israel would ruin all he has worked to acomplish.Iran has also been boasting of their stealth missle, the problem with that is their radar systems are no were near effective as the radar systems that the US currently has. The Iranians claim that their missle is capable of sinking an aircraft carrier. what they are not taking into account is their missle has no were near the range required to hit an aircraft carrier in the Indian Ocean. also, the US would launch planes based in Iraq, Afghanistan, Diego Garcia, Qatar, and Turkey to bomb military instalations early on in any conflict with Iran, so their missle would likely be distoried before they knew what happened. I say they'd launch planes from ground based locations because the FA-117, B-2, F-22 and B-52 aren't able to land on a carrier. those are the US principal bombing aircraft, and the 117, and B-2 are both stealth, and like I said before the Iranian radar systems are out dated. The only way Iran could use that missle would be to do a pre-emptive strike, which again would be completly stupid because they would lose support from countries like Russia, which means no arms, and no enriched Uranium. thus they'd likely get bombed into the stoneage and left that way with no rebuilding help from the US.Even if there is a war with Iran, which I think is highly unlikely, I don't see the US sending in many ground forces. the occupation of Iraq, and Afghanistan has spread US forces to thin as it is. so any conflict would likely just be airial and naval bombardments with special forces going in to eliminate key targets.
