Obama in Egypt

President Obama will give what could be one of the most important speeches of his presidency on Thursday when he addresses the relationship between the United States and Muslims.

In his speech, to the University of Cairo, he will hope to break with the hostility of recent years and set a new tone designed not only to isolate the extremists of al-Qaeda and the Taliban, but to re-establish the understanding America gained on 9/11 and lost in Iraq.
