If you're really interested in the story about Iran and our plans there, read this article by Seymour "Sy" Hersh.

He is a highly respected reporter with lots of sources inside the intelligence community and the DOD. There was the big report about possible plans to use tactical nuclear weapons here. Pres. Bush called it "wild speculation", but after reading the article you'll see why he didn't call it a damn lie.
The noted parallels to the runup to Iraq are eerie -espeically the statements by Condi Rice this week. People would question how we could do this, with our forces stretched in Afghanistan and Iraq, but the plan would be for a massive air campaign with limited feet on the ground as spotters (and who are already in place).
One quote: "A government consultant with close ties to the civilian leadership in the Pentagon said that Bush was “absolutely convinced that Iran is going to get the bomb” if it is not stopped. He said that the President believes that he must do “what no Democrat or Republican, if elected in the future, would have the courage to do,” and “that saving Iran is going to be his legacy.” "
Of course, I've never known a president in political trouble on the home front turning to foreign action to rally the populace.
After reading the reactions of the Joint Chiefs of Staff to these plans (they are against them), I believe that the calls by five retired generals for Rumsfeld's resignation stem not so much from his horrible blunders in Iraq, but from a desire to stop him before this Iran plan can get underway. I think we're much closer to this plan happening than many people realize. Check it out.
