I am unfortunately unable to comment on your other points, truer_sound, but Wilson did try to prevent the Treaty of Versailles from being written the way it was. At least, that's what I learned in American History. He wanted there to be no retaliation against Germany, among other things, and he was shouted down. Was it his 11 point plan? I think so. Sadly, I am too ignorant to know if that is the correct number. If anyone knows better, please feel free to post.
