Obama's entire speech in Cairo. It is well written, probably well orated as well, and deeply rooted in human rights and dignity as the center of all policy making and solutions. A couple of excerpts:

It's a story with a simple truth: that violence is a dead end. It is a sign of neither courage nor power to shoot rockets at sleeping children, or to blow up old women on a bus. That is not how moral authority is claimed; that is how it is surrendered.

and on democracy:

America does not presume to know what is best for everyone, just as we would not presume to pick the outcome of a peaceful election. But I do have an unyielding belief that all people yearn for certain things: the ability to speak your mind and have a say in how you are governed; confidence in the rule of law and the equal administration of justice; government that is transparent and doesn't steal from the people; the freedom to live as you choose. Those are not just American ideas, they are human rights, and that is why we will support them everywhere.

Each time an issue is expounded upon in the speech it comes back to the freedom inherent in political rights and the dignity of self-expression and self-determination. The latter becoming truths in their own right. Quite impressive.

I think one of Obamas strengths is that he doesn't treat constituents like idiots or children, or even stupified consumers of media. He doesn't 'catapult the propaganda' so it sinks in either. He is prepared to speak on tough issues, triangulate the best mechanisms through discussing the issue from multiple points of view but with the grounding of political rights, human dignity and self-determination.
