Ukraine

Possibly. I do hope that we'll just be "late" like we were in WW2. A lot of people forget we were largely isolationist and waited way too long before getting involved in the conflict. The Allies ultimately prevailed, but it very easily been flipped had some key decisions been different.
And a lot of people forget, or don't know, that russia joined Germany in invading and occupying Poland. They were a member of the Axis that consisted of Germany, Italy, and Japan. It was only after Hitler broke his agreement with Stalin that russia joined the allies. And they would have been over run by Germany if not for getting help from the U.S.. War has a way of bringing the bad together with the good in order to survive.

The 1920s, so far, have been an eerie mirror to the 2020s. If we start getting deeper into the 1930s, I have to wonder who will be playing which part in this historical repeat.
