I think the point that he was making is that America and much of Europe like to imagine wars as faraway struggles that we do our best to avoid thinking about at home, while Hitler made militarization the national pastime. Compare the Boy Scouts with the Hitlerjugend, for instance.
It’s not that the Allied nations were at the time less militaristic (although they were, of course, not also committing mechanized genocide against the Jewish people), but they didn’t conceptualize it as a form of entertainment like the Nazis did.
