This is a ridiculous argument. Reasonable people would have supported a bombing of the death camps even if a few inmates died in the process if it stopped the killing machine for a significant period of time, not to mention the killling of the guards and other personnel who would have had to be replaced as well as rebuilding of the camps. Maybe the Nazis would have even quit rebuilding after a couple of bombings. Nobody is saying the US is responsible for the Holocaust however, that is not to say we could not have done more to stop it or slow it down.
Try and imagine yourself being the one who had to make that call. In the mind of the President would have to be the glimmer of hope, however slight, that the Germans would take out Hitler and capitulate "any day now". "What if that occurred on the very day after I, the now-infamous-villain of all time, bombed 20,000 Jewish victims to death". Hindsight is clear, but there were many other military contingencies of the moment that people are forgetting nowadays, and it is unfair, I think.
And my argument is not ridiculous. If it were, I wouldn't use it. No legitimate FReeper makes ridiculous arguments, and to characterize them as such, when they represent legitimate, well-founded differences of opinion, is beneath our dignity on here, I think. Still, far too much trashing of fellow-conservatives goes on. Disagree, of course! Politely.
The US knew there was only one way to stop it: defeat the nation perpetuating it. That we did. Planes diverted to bomb a camp served the purpose of ending the war far better by destroying Germany's ability to make war.
Besides, Auschwitz is in Poland. No American airplane had the range to reach it.
