"There never was a good war or a bad peace."The "peace" leading up to ww2, in which Britain basically gave the Sudetenland to Hitler in exchange for peace, was a bad peace, IMHO.
Any peace which coincides with injustice, especially injustice on a huge scale, is a bad peace.
Whether or not a war would be better is perhaps another question. I think Britain might have saved a lot of lives if they had invaded Germany many years earlier, instead of appeasing the madman.
Of course it's easy to armchair quarterback a war that's over half a century distant.
