Barack Obama has managed to be both right and wrong at the same time.
On the one hand, he is correct - we don't get "do-overs" in time of war. On the other hand, he wants to cut and run. In essence, he'd be telling Iran, Syria, and al-Qaeda that if you keep racking up spectacular attacks that grab the headlines and kill innocent people and the occasional American soldier, America will quit.
That is not the message I want to send to Bashir Assad, Mahmoud Ahmadinejad, or Osama bin-Laden. We only get one chance to send the right message. I want it to be, "Piss us off, and you will be lucky if you end up like Saddam", not "We're wimps."
Stephen Ampbrose had a wonderful phrase in his book, D-Day that describes what we are dealing with: The poison of pacifism. The Democrats have taken a massive dose since the Vietnam War. We even have one of their candidates claiming the war on terror is a bumper sticker slogan. I wonder how the victims of the 9/11, Bali, Madrid, and London attacks would feel about that.
