At the one minute mark Obama reminds us why we are in Afghanistan by invoking 9/11.:
"To address these issues, it is important to recall why America and our allies were compelled to fight a war in Afghanistan in the first place. We did not ask for this fight. On September 11, 2001, nineteen men hijacked four airplanes and used them to murder nearly 3,000 people. They struck at our military and economic nerve centers. They took the lives of innocent men, women, and children without regard to their faith or race or station. Were it not for the heroic actions of the passengers on board one of those flights, they could have also struck at one of the great symbols of our democracy in Washington, and killed many more."
... So I take it you ignored Charlie's letter then.
The thing is ... for all we know, he may actually have been telling the truth ... it all depends which nineteen men he was referring to! Here's sixteen for ya!
