Joe Klein chides Clark:

I think McCain's Vietnam war experience gives him important perspective on the horrors of war and should never, ever be discounted--even if McCain's more recent positions have been unduly bellicose. It's also just really bad manners on Clark's part, given the suffering McCain endured. I disagree with McCain's foreign policy positions in the middle east--you may have noticed--but he has traveled widely and, I believe, has worked hard to learn the rest of the world, especially the countries that spun out of the former Soviet Union.
