I grew up in a very loving middle class family. My parents were educators. I'm not even the first PhD in my family. They tried to shield me, just as other parents in my neighborhood tried to shield their children. But you knew there was a reason that you couldn't go to that theme park or to a movie theater or to a hamburger stand. They couldn't shield you completely. What they did though was they never let it be an excuse for not achieving, and they always said racism is somebody else's problem, not yours. They tried in that way not to make us bitter about Birmingham.

I don't know anyone who is more admired and respected in the international community than President Karzai, for his strength, for his wisdom and for his courage to lead this country first in the defeat of the Taliban and now in rebuilding a democratic and unified Afghanistan. And I can tell you I am with foreign ministers and with heads of state all over the world. I sit in the councils of NATO. I sit with the EU. I sit with people all over the world and there is great admiration for your president and also for what the Afghan people are doing here.
