Maybe each generation needs a crisis ? It was usually wars in the past but its a pandemic now ? Something to tell to the next generations, just instead of dodging bombs its dodging an invisible danger ?

Not all crises are equal. This current one didn't really bring people together. And although I wasn't around to see it, it's hard to imagine 40% or whatever of the population in 1942 were all, "that guy in Germany isn't even so bad, in fact I don't think he even exists at all, I'm going to hoard aluminum and steel for personal use now."

That was mostly the case in 1939 though ¯\_(ツ)_/¯

I think it actually did bring people together. In the UK at least there has been a noticeable change in the national atmosphere.

Holocaust denial is a thing...

When the youngest generation has not known a period when there was NOT a war, something else needs to happen.

From what scientists are saying about the climate crisis, we are going to enter an era of continual crises unless major action is taken.

Why not both?

covid is the excuse not the reason. but fun times for those at the top.
