I agree. People confuse imperialism with Nazism too easily. It's not necessarily that society is controlled by Nazis, but that imperialism is considered (by Lenin) as the highest stage of an economic system driven by the continual growth of capital. To tie things back, the OP cites a liberal empire as a possible solution to the problem of US-style Dr. Mengeles, but I see the empire overriding the liberal in the first place. The focus on "the Nazis", absent of serious analysis of the philosophical context that gave rise to them, can end up ignoring what made people believe in the ideology in the first place. There's a particular mythological victimhood for Nazis where the only way to break free is to create their own empire to subjugate (and exterminate) who they viewed as parasites. This ends up being highly problematic when people groups are viewed essentially only as good as their stereotypical economic function. A liberal empire isn't concerned with rectifying people's economic function outside of markets and incentives. This leaves wiggle room for exploitation that lead to the US-style Dr. Mengeles experimenting on poor people (which also has a racial element since minorities can tend to be poorer.)
