Think about the political policies of Britain immediately prior to WW2. If a party today advocated just rolling back to those policies verbatim, they would be called Nazis immediately.
Just stop for a second before reacting - that's pretty weird, right? The policies of the heroes of the story who literally fought the Nazis, would today be put in the same bucket as the Nazis. Huh?
Same with American policies immediately prior to WW2. If a party wanted to roll back to that, literally Hitler! But that America fought Hitler. But that America would be lumped in with Hitler. Weird, right?
They went to war to fight Germany's, Japan's, and Russia's attempts at geostrategic hegemony. If Germany, USSR, and Japan had stayed in their geostrategic lanes, they wouldn't have invited a war on them.
This seems to imply a social ideology rather than a geostrategic one. The term "Nazi" is used for a specific brand of social ideology, not a general term for imperialist policy.
Which policy rollbacks were you talking about?
