Carville's last line in the transcript sums up his position:
CARVILLE: Of course, the Iraq thing is why people have so much trepidation about going into Syria. They said the last time we went over there, look what happened. I really think this has something to do with it.Except that Iraq wasn't the last time that we went over there. There was a little adventure called "Libya" that went south in a big way. Carville also has a funny way of looking at success. He cites the revolutions in Tunisia and Egypt, but the Egyptian revolution replaced a moderate, pro-US regimes with an Islamist, anti-US regime, and is rapidly devolving into a civil war. Tunisia is about where Egypt was before the military coup. They had elections in October 2011, and put the Islamic party, Ennahda, in power (not with a majority, but 41% of the total vote, enough to get them into the position to create their own little caliphate). That's not success, unless you consider empowering terrorist enablers success.
Carville was the Baghdad Bob of the Clinton administration, and the role model for Beltway Jay.
