Why did he talk about Finland anyway? You didn’t mention Finland, unless I missed something.

Second, he didn’t include a timeline of Finland:

-August 1939: Russia becomes allies with the Nazis

-November 1939: the Nazi ally, Russia invaded Finland.

-June 1941: Finland joined the Nazis in betraying and attacking the Nazis’ ally, Russia. So, the enemy of my enemy is my friend.

Tldr: Russia joined the Nazis of their own free will. Finland joined trying to repel an invasion.
