The reason it matters is the common genetics of all modernist ideologies have something in common that they think they're rational, logical, and empirical. Socialism, national socialism, and fascism all share that they think that they are scientifically the obvious way to run the world.

If you think that your method of running the world is rationally, logically, empirically, and scientifically the obvious and correct way to run the world, then there's going to be an ideological coherence and unity among people, and a willingness to do whatever it takes to promote that ideology. It becomes a moral good to push your ideology. In that sense, if National Socialism came to pass without Bolshevik soviets to the east, it's probable that they would have been the aggressive hornet just the same.

Even liberalism (which is more enlightenment immediately before the modern period) has this problem, and so after it "won", it turned into neoconservatism which wanted to take over the world and install itself as the single correct ideology for planet Earth.

So you're not wrong, but modernism was always fated to die the way it did by ramming totalitarian ideologies against each other until they break, because that sort of epistemological arrogance and stupidity is built in. That will eventually result in totalitarianism and expansionist ideas because when you're convinced you've found the mathematically perfect way to live you have a duty to spread your mathematical truth.
