I wonder if the political will exists to take on the Iranians. I can see it now the media will be asking if the proof of Iranian involvement is similar to the Iraqi WMD proof and the public will lap it up, followed by the inevitable "I told you it's all about oil" from the left. It doesn't help when Hamid Karzai says Iran is Afghanistans good friend and wouldn't do such a thing. The consequences militarily suck pretty badly as well. I'm sure we have enough bombs to make life miserable in Iran, but can we handle another war at this point? Seems we're stretched pretty thin already and the Iranians know it.
