“ He could be wrong, and in fact, is, when it comes to foreign policy. Foreign policy is an area where one can be right one moment and wrong the next. Thus, the Henry Ford analogy fails at that point.”

Actually, that’s exactly where the Ford analogy makes sense. Firs was in favor of Hitler’s eugenics policies…until, after the war, he saw films of what those policies produced in the way of human misery and atrocities. But at that point it was too late to change what he had done and said. He changed, like many others, when confronted by facts contrary to his previously-held beliefs.
Actually, what you posted is exactly what I was saying. One can be right or wrong when first expressing an opinion, then see the opposite later on. Thus, if one is not in the field of foreign policy, it’s best left to those what know the field better.
