I don't think I mentioned the Nazi's, but since you bring it up.
"From the prosperity of the empire during the Wilhelmine era (1890-1914), Germany plunged into World War I, a war it was to lose and one that spawned many of the economic crises that would destroy the successor Weimar Republic."
"During the Hitler era (1933-45), the economy developed a hothouse prosperity, supported with high government subsidies to those sectors that tended to give Germany military power and economic autarky"
Economic crises inducing a transition from democracy to plutocracy/fascism, and massive military spending, ending in wars on multiple fronts.

I suppose I should also qualify my statement as "dominant states". Since the most common way for small states to be converted to fascism is by the dominant state (i.e. USA) installing fascist/authoritarian governments for them. So I concede that, in general, you may be right.
