John McCain claims to be a brave war hero. So why is he afraid to even talk to Iran? As Jonathan Singer writes,

The Obama campaign is completely right to invoke Presidents Kennedy and Reagan in talking about the importance of speaking with both friend and foe. They might have even invoked Teddy Roosevelt, who McCain claims to model his career after but who in fact McCain seems to know and understand little about, a President who won a nobel peace prize while in the White House specifically because of his willingness to engage with the world.

But I'd go even a step further and ask why John McCain is afraid to speak with Iran. What is it about Iran that scares McCain so much? Or is it that McCain believes Mahmoud Ahmadinejad and Ayatollah Khamenei are so crafty that they would trick an American President into inadvertently ceding the state of Maine or American Samoa to Iran? Or alternatively, is it that McCain simply does not know how to act in a manner different from his true political role model, George W. Bush?

Here's a simpler possibility: John McCain is simply a coward, just like all the macho war criminals in the Bush Administration.
