I guess it depends on your definition of "constantly". To me, if it's cyclical and followed by a national debate, it's different.

I'm certainly not debating that nationalism didn't (or doesn't) exist in Japan. I just wonder to what level it was "indoctrinated". I would have expected there to be far broader and stronger nationalism left today if it was that bad post-war. I'm trying to compare to stuff like how the effects of the Red Scare in the US are still very strong
