The above was a wargame, run by the Heritage foundation and top US officials. It took four months. It's long been said that Bush would not leave office without "resolving" the Iranian Nuclear problem. Many have theorized that Bush was bent on war with Iraq because of Saddamn's attempt on his father's life and because he felt the continuation of the Hussain regime was a black mark on his father's record. Well, a similiar motivation may be at work with respect to Iran: Regardless of the motivation, plans seem to be in an advanced stage with US special forces already in place getting intel on potential targets. Why special forces and not the CIA? I'd also expect that special forces would be much better in terms of security as CIA seems to leak like a sieve. They have even lined up some allies: Still, this is not a sure thing. The costs of war with Iran would be huge: On the other hand, the administration thinks they have a solution: http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2007/09/02/wiran102.xml&page=3 So I'd say it's a matter of waiting for an appropriate casus belli, or definite proof of Iran giving up its nuclear ambitions (not likely, I'd guess).
