Not sure what is there to laugh at when millions died in pretty horrible ways including americans, anyway that was classical war mongering where one of the parties got exactly what they wanted (prussians/germans). That they got more than they wanted and how it folded them is part of history.

This case, its bullshit machine bullshitting randomly in between specs of stolen wisdom. Nobody asked for that, nobody is in control. We all humans lose in all cases. Quite different scenarios if you asked me.

Dark/gallows humor is a thing, and also plenty of people use humor as a coping mechanism.

It's fine not to share the same sense of humor, but if you truly lack an understanding of what someone else would find to laugh at that's an easy thing to learn to broaden your understanding of the world.
