I know all about that. But it's not a grudge. It's their commemorative history. The USA has the same exact thing. The Turks do. So do the Greeks. So do many peaceful countries. The US has Bunker Hill, to give just one example.

I would contest this idea of a pressure cooker being removed causing the mayhem. It was not that which caused it. It was the division of land/property without any regard for a fair division among all ethnic groups. That's what caused it.
