WWII started in 1939 and was done in early 1945, so it didn't take that long.
More importantly, maybe the Nazi's were competent at first, but they absolutely fell apart internally due to mistrust, back stabbing, and demanding of loyalty above all else. Hitler famously made many poor military decisions.
The Nazis were in power for years before they started WWII.
