"The previous century" includes the Great Depression, WWII, the Cold War, a bunch of nuclear war close calls, and 9/11. Also if you include the whole 20th century, WWI and the Spanish Flu.

And those are just of the top of my head, I'm sure I've missed some.

Personally, I'm not sure this pandemic qualifies as "one of the most difficult"...

It's almost as though you're responding to a different statement than the one that I made. What about what I said would have denied that any of those things you mentioned were not also terrible things that are among the worst things in the past century?

In terms of death toll for my family, more people died in the last year due to Covid than all of those events combined. So yeah, I would put Covid right up there at the top.
