I extremely disagree with the idea that the German military opposed the Nazi party. For one thing numerous members of the military, especially up and coming division and corps commanders, were either party members or party supporters. Walther Model is a typical example. Many other hard right conservatives, while ambivalent or leaning towards the party, had many views that agreed with its own especially regarding foreign policy. Many were very militaristic and did indeed support the war; only a small faction (The ones at the very top) were wary of the war. Wary, not opposed, as German victories soon made most feel that they had underestimated the abilities of the military. An armistice in 1941 is simply not going to happen, and neither is any victory in Africa. Logistics won't change with Goering in power, and a new commander or a bit more air support won't help things out. Germany had demobilized much of the economy and only re-mobilized in preparation for war with the Soviet Union.
