Khalilzad (currently US Ambassador in Iraq) is a good guy. I don't care whether he is Afghani by birth or not. He wouldn't be the worst choice. I have no problem at all with Khalilzad...
Just what would you have a problem with?
Agreed. He may have a little more credibility at the UN because of this background (trying to say nicely that there are racists at the UN too) and I have heard him be very articulate about American interests.
