We temporarily renamed some fast food that wasn’t even correctly named after them, and made a bunch of juvenile jokes about their performance in WW2 for a couple decades. I dunno, I was just a kid at the time, but I didn’t get the impression that we were taking their complaints very seriously.

I was a little bit older, and I do remember the hostility we had towards them (I was studying French at the time). But yeah, it was more like the way you'd boo the opposing sports team, not like we are at risk at war with them or anything...
