Obama: Al Qaeda Responsible for 9-11

It's just a tiny part of his speech in Cairo, but appreciated nevertheless:

The situation in Afghanistan demonstrates America's goals, and our need to work together. Over seven years ago, the United States pursued al Qaeda and the Taliban with broad international support. We did not go by choice, we went because of necessity. I am aware that some question or justify the events of 9/11. But let us be clear: al Qaeda killed nearly 3,000 people on that day. The victims were innocent men, women and children from America and many other nations who had done nothing to harm anybody. And yet Al Qaeda chose to ruthlessly murder these people, claimed credit for the attack, and even now states their determination to kill on a massive scale. They have affiliates in many countries and are trying to expand their reach. These are not opinions to be debated; these are facts to be dealt with.
