I further challenge you to read Buchanan's book CHURCHILL, HITLER, AND THE UNNECESSARY WAR (2008), and try again to allege that Buchanan is pro-Hitler. While he describes Hitler as brutal, he puts forth the evidence that the British, and particularly Winston Churchill, are just as much to blame for both World Wars, and that Hitler and the Germans were pushed toward two wars they never wanted.
The Germans up until both wars wanted to be partners with the British, and viewed the British as their natural allies. But in both wars were pushed into war with the British they never wanted.
If Britain had not signed a secret pact to side with France, the Germans would not have declared war in World War I, they would have told the Austo-Hungarians to negotiate with Serbia.
If Britain had not given Poland a war guarantee in 1939, Poland would have negotiated into a very reasonable proposal by Germany (giving up only the city of Danzig, and allowing Germany to build highways and railways over the Polish corridor to connect East Prussia with the rest of Germany).
And Germany would have focused all its energy on attacking Russia, leaving the British and French empires (along with Norway, Denmark, etc., taken as a defensive move against a British pre-emptive attack) untouched.
