Reza Aslan in washingtonpost.com:
As someone who once was that young Muslim boy everyone seems to be imagining (albeit in Iran rather than Egypt), I'll let you in on a secret: He could not care less who the president of the United States is. He is totally unconcerned with whatever barriers a black (or female, for that matter) president would be breaking. He couldn't name three U.S. presidents if he tried. He cares only about one thing: what the United States will do.
That boy is angry at the United States not because its presidents have all been white. He is angry because of Washington's unconditional support for Israel; because the United States has more than 150,000 troops in Iraq; because the United States gives the dictator of his country some $2 billion a year in aid, the vast majority of which goes toward supporting a police state. He is angry at the United States because he thinks it has hegemony over almost every aspect of his world.
Now, more than one commentator has noted that on all of these issues, the next president will have very little room to maneuver. But that is exactly the point.
He then lists the work ahead, on Israel/Palestine, Iraq, Syria and Iran, Syria and Lebanon, Saudi Arabia's leadership succession, Afghanistan and the Taliban, Pakistan, and Chinese involvement in the Middle East region.
That is how the post-Bush "war on terror" must be handled. Not by "re-branding" the mess George W. Bush has made, but by actually fixing it.
The point being, when picking a president, pick competence, not a symbol.
