I disbelieve. When Hitler invaded, he immediately put his plan from Mein Kampf into action, and tried to consolidate control and create Lebensraum (aka "living space") for the German people. He had made his desire for that invasion clear many years earlier.
If Hitler hadn't been a deranged fool he would have not sent the SS into Czechoslovakia (which turned the initially rejoicing population hostile), and would have immediately drove right for Moscow. Had he done that the Russians would have had no communication lines, which would have made it massively harder for them to organize a resistance.
Hitler in some sense was the best friend the Allied forces had. Every time he made a major military decision (eg "let the English rescue all of their troops at Dunkirk") it turned out to be really stupid. And the conduct of the Russian war shows lots of examples of that.
In particular note that the claim that the Nazis were attacking first to head off a counter-attack is a claim the Germans made during WW II. However there is little evidence for this, and Stalin's instructions to his generals in December of 1940 suggests that the Soviet Union knew it would eventually be invaded, thought it would easily be ready in 4 years, and was trying to put the invasion off for at least 2. When the invasion came in May they were caught unprepared and by surprise.
