It's no surprise that skeptics, both domestic and international, are emerging on the alleged evidence of "illicit weapons" in Iran. Since it's obvious that the administration lied--or at the minimum, sloppily accused--Iraq of harboring WMDs, the burden of proof is going to be much higher this time around. While there are obvious reasons that an administration needs a certain level of secrecy, it seems more likely that the evidence presented to a select group of journalists recently is a distraction for how badly the war is going in Iraq.
What's more, our troops are already badly stretched. If Bush really wanted to send troops to Iran, he'd be in a slightly more than sticky situation.
