Byron takes us to task on the Feedback page for oversimplifying a complex issue in Yes or No. In that post I wondered why people like Letterman seem unwilling to give a straight answer to the question of whether they want the U.S. to win in Iraq. Winning in Iraq means, of course, accomplishing our stated goals (What else could it mean?), and these from the beginning have been to establish a free nation based on democratic principles, human and civil rights, and a stable government free from the threat of terrorism.
I don't think the question is nearly as complicated as Byron does, but you can be the judge.
