He opposed it in all circumstances. He was no liberal. In World War II, the Japanese added "amendments" to the Geneva Conventions for the specific war with America. Sound familiar? Money quote from my friend Niall Ferguson:
[E]ven if you don't see any resemblance between Bush's "administrative regulations" and Imperial Japan's "necessary amendments" of the Geneva Convention, consider this purely practical argument: As Winston Churchill insisted throughout the war, treating POWs well is wise, if only to increase the chances that your own men will be well treated if they too are captured. Even in World War II, there was in fact a high degree of reciprocity. The British treated Germans POWs well and were well treated by the Germans in return; the Germans treated Russian POWs abysmally and got their bloody deserts when the tables were turned.
Few, if any, American soldiers currently find themselves in enemy hands. But in the long war on which Bush has embarked, that may not always be the case. The bottom line about mistreating captive foes is simple: It is that what goes around comes around. And you don't have to be a closet liberal to understand that.
