Although he was a fool, I do believe Chamberlain did have some personal honor. I'm beginning to think this guy is more along the lines of Lord Haw Haw.
I agree with your assessment of Chamberlain. He was wrong, but well-intentioned and patriotic, whereas today's Chamberlains are often America-phobes, Christo-phobes and UN-Worshippers. He was man enough to admit his mistakes too, IIRC.
