If memory serves, I believe ol' H.L. couldn't come to understand how we could side with Britain in the two great wars of the 20th century. He thought the Kaiser and Hitler were just two misunderstood dudes.
Not true as to Hitler. He may not have believed we had cause to get involved in WWII, but I'd be surprised if you can locate a single pro-Hitler quote.
"Democracy is the theory that the common man knows what he wants, and deserves to get it good and hard."
He was right about the Kaiser, who we should have backed. Unfortunatly, Anglophile Roosevelt had other ideas.
