Last night McCain  asserted that Obama's position that the US should attack Bin Laden in Pakistan if Pakistan's government cannot or will not represented the opposite of Teddy Roosevelt's "Speak softly, but carry a big stick" adage.  Obama tartly responded that McCain is not in a position to accuse anyone of undiplomatic bluster, given that he "is the one who sang Bomb, Bomb, Bomb Iran."

Here is the exchange, from CNN's debate transcript.

Obama: Sen. McCain, this is the guy who sang, "Bomb, bomb, bomb Iran," who called for the annihilation of North Korea. That I don't think is an example of "speaking softly."

This is the person who, after we had -- we hadn't even finished Afghanistan, where he said, "Next up, Baghdad."

McCain: And, Tom, if -- if we're going to go back and forth, I then -- I'd like to have equal time to go -- to respond to...

Brokaw: Yes, you get the...

McCain: ... to -- to -- to...

Brokaw: ... last word here, and then we have to move on.

McCain: Not true. Not true. I have, obviously, supported those efforts that the United States had to go in militarily and I have opposed that I didn't think so. I understand what it's like to send young American's in harm's way. I say -- I was joking with a veteran -- I hate to even go into this. I was joking with an old veteran friend, who joked with me, about Iran.

Problem is, millions of Americans have seen McCain singing his reckless and stupid "Bomb Iran" ditty with their own eyes, either on the news, or on this popular YouTube video.

As the familiar video shows, McCain sang his "Bomb Iran" song in front of cameras and in response to an audience question at a primary campaign event.  His effort to dismiss it as part of a joking one-on-one discussion with an "old veteran friend" is directly contrary to immediately accessible visual evidence.  

This is downright bizarre behavior.    McCain lied about something millions of Americans have already seen with their own eyes, and that is readily available to others.  What is up with him?
