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.

Six years for a country holding back the allies is not "that long" - and 6 years more since they came into power?

And as a government they'd still be in power 20 and 30 years later if they didn't start the war (judging from Franco's spain).

The Nazis were in power for years before they started WWII.
