WI: Hitler knows what he's getting into immediately prior to Barbarossa

I think that's really the question I'm asking here, wro. Was Hitler so crazy, even at the height of his power, that he really wouldn't have cared what information was put before him, or how credible it was, that he was committing national and personal suicide? Sure, he believed in the power of the "will", and his own and Germany's national superiority. But, that didn't prevent him from being very devious and effective indeed, in acquiring territory, between 1934 and 1939. And, in acquiring it without any significant military confrontation. That didn't prevent him from writing off the possibility of an invasion of Britain by mid-September, 1940, because he could see he simply didn't have the Navy to pull it off. The fact is, Hitler's military intelligence was terrible prior to the Soviet invasion, and his Generals thought an easy victory was just as likely as he did, according to their own private diaries, although they denied this systematically to save their skins, at Nuremberg. Actually, American intelligence thought the same way, they thought the Russians were finished by mid-July, 1941. In this particular case, and at this time, it is by no means inconceivable that Hitler could have faced facts, if he'd known about them. He certainly did, at times, and he had a great deal to lose, in Spring 1941. The real question is how crazy Hitler was, versus how practical. He was capable of being either, to an unusually high degree. Another interesting question is to what extent Hitler himself -- often a master manipulator -- was at this time himself being manipulated, particularly by British intelligence. I've always wanted to take a look at the MI5/6 interviews with Hitler's old school chum, the philosopher Wittgenstein, but they're still classified. Possibly Wittgenstein himself was assisting the British into manipulating Hitler into an invasion of the Soviet Union, something that would have been a very high priority indeed for Winston Churchill. Possibly Stalin himself preferred a full scale invasion of the Soviet Union to the possibility of Hitler humiliating him by simply force him back to his 1939 borders, something Hitler could certainly have done. Stalin may have wanted to entrap Hitler in the depths of the Soviet Union, just like Alexander I did with Napoleon. That is what he did, ultimately, after all. Certainly, both Britain and the Soviet Union would have feared Hitler conquering the the Middle Eastern Oil Fields and the Suez Canal, something he certainly could have done in 1941-42, if he'd avoided Barbarossa. Even Japan had its reasons for desiring a Nazi invasion of the Soviet Union. With the Soviet Union occupied, Japan had nothing to fear from its Western flank, and was free to concentrate on the U.S. Hitler may not have been so much delusional in attacking the Soviet Union with the intention of full conquest. Hitler may have systematically manipulated by Britain, Japan and the Soviet Union, combined!
