Here is a sampling of more professional opinions, separate from ravings from the peanut gallery:
TIME’s Scott McLeod Wrote, “President Obama’s Speech In Cairo Today Is The Most Important Address Ever Given By An American Leader About The Middle East…He Didn’t Arrive Or Depart As A Prophet, But For An American President Treading Into Territory Inhospitable To U.S. Policies, He Won Some New Adherents.” On TIME.com’s blog, Scott McLeod wrote, “President Obama's speech in Cairo today is the most important address ever given by an American leader about the Middle East. As he told 1,000 people at Cairo University and millions more around the world, everything won't be solved by a speech. Yet it was an unprecedented reach-out to Muslims and particularly to the Arab world. Far more than any other U.S. president in the past, he both acknowledged harmful Western policies during the Colonial and Cold War eras and promised an intense personal effort to resolve the region's problems and build a new era based on mutual cooperation and respect. The clear message Obama delivered—in his words, body language and statement of policies-- was that America is determined to be part of the solution in the Middle East. He didn't arrive or depart as a prophet, but for an American president treading into territory inhospitable to U.S. policies, he won some new adherents.” [Scott McLeod, TIME.com, 6/4/09 <http://mideast.blogs.time.com/2009/06/04/obama-in-cairo-the-making-of-a-prophet/> ]
