I think the German government is opposed for various reasons. In the early stages of West Germany, the victors permitted only those parties that preserved their interests. The provisional constitution and penal laws, both still valid at present, bear the hallmarks of the victors. Those who argued against the official version were convicted for "hate speech" and the like. To publish newspapers and magazines, concessions were needed and only given to those who complied, resulting in a huge head start for some, e.g. Der Spiegel. The Allies also conducted the greatest book burning ever, destroying vast amounts of German literature that was no longer wanted. I mentioned before that the German government had to sign transition contracts that stated all Allied rulings were rightful and legally binding, including the Nuremberg trials that established the sole war guilt of Germany. Those who wanted to make a career in politics in post-war Germany quickly realized how they had to run things.
As for the invasion of Russia, some authors like Viktor Suvorov made the case that this was a pre-emptive strike. Hitler thought that war against international Bolshevism was inevitable but Stalin didn't expect an attack as long as Germany was still at war with Britain. German military intelligence found indications that a Soviet invasion was being prepared and taking Russia by surprise was considered the only chance to survive. The huge Soviet losses were partly attributed to the offensive positioning of their army, e.g. Soviet artillery couldn't operate properly due to the lack of topographic maps of their own territory.
