That's total nonsense.
Common sense and simple sanity would silence you, if you had any, FRiend.
In my small library of WWII books, I have two which make similar points to your Diana West's.
They are Patrick Buchanan from 2008: "Churchill, Hitler and the Unnecessary War -- How Britain Lost Its Empire and the West Lost the World", and
Guido Giacomo Preparata from 2005, "Conjuring Hitler -- How Britain and America made the Third Reich."
Buchanan argues that the US should have stayed out of WWII and forced Britain to make peace with Hitler, while Preparata goes even further, claiming that the US & Britain actually put Hitler in power so that they could then destroy Germany.
Point is: I'm very familiar with wild conspiracy theories, and they're all just nonsense.
To see this, you have only to honestly answer the following questions -- was it Stalin or Hitler who first invaded:
As for your concerns about the Democrat Left's war on America, I'm sure I agree, but remember this: the choice in, say, 1941 was not between Left (Stalin) versus Right (Hitler), but rather between the far-far Left (Hitler) and the far-far-far Left (Stalin).
Both sides were anathema to American ideals of liberty and limited Constitutional government, but only one side (Hitler's) declared & waged war against the United States.
Hollywood and the Government education system did a really good job on you. “Germany itself needed to be utterly destroyed” this involved the starving to death of infants and young children. That was a Satanic policy you advocate. Are you any better than a Nazi? Read The Morgenthau Plan: Soviet Influence on American Postwar Policy.
