Yes, Molly Ivins certainly knows her cant.
The difference is, people like Molly are really looking stupid these days, and more than a little desperate. One might even say... envious.
For what it's worth, I never really bought into the idea of treating prisoners of war as anything other than criminals. Either they were on the right side of the war, or they weren't. If they were, then their captors are the bad guys, and aren't likely to care about their rights. If not, then they're international criminals, and should be dealt with accordingly.
The Geneva Concention is a misguided effort to civilize war. You can't civilize war. You can only get it over with.
