This was really Obama at his best -- candid, realistic, passionate, idealistic and level-headed. This is probably the closest thing we have to a personal articulation of Obama's fundamental beliefs about America's role in the world.
The subtext of Obama's speech is that he can be exempt from the constraints of moral leadership implicit in the receipt of the Nobel Prize and still use it as a political marketing tool. But it doesn't work that way.
What better way for Obama to begin his labors of peace on the world stage than by impaneling a Truth Commission to investigate the wrongdoings of the Bush administration regarding their pre-emptive war with Iraq?
