What would Joe McCarthy do?

Not a fully formed post. (As if any of them are). But I was fiddling around on Wikipedia and came across an interesting fact about Joe McCarthy. The only other thing that he seems to be known for is his opposition to the death sentences handed down to the Nazi perpetrators of the Malmedy massacre. I sure politics played into it, but he argued that since the confessions that these men signed were given under torture that the hearings were unfair and unbecoming of America and its rule of law.

Many of the torture techniques that were used against the Nazis are very similar to the rough interrogation techniques used at Gitmo on the enemy combatants.

If McCarthy, one of the most strident right wingers ever, refused to accept torture on Nazis (the modern day all purpose villain) who gunned down 88 unarmed American POWs and left their bodies in a field to rot, would he have green lit the types of trials and conditions that W is using now for people who were simply handed over to the US for a bounty?
