US Ready to Attack Iran

Well, let's see. The US now has several carrier groups and 2 destroyers in the Gulf. And according to this BBC article, we even have an attack plan ready. The trigger for such an attack would be either evidence of Iran building nuclear weapons, or evidence of Iran directly backing an attack causing massive US casualties in Iraq. Hmmm . . . Let me play Kreskin. I see . . . a man sitting in front of Congress, showing "evidence" of an Iranian attack. Wait, wait! Now I see a man showing pictures of an Iranian nuclear program.
