It's not this movie and series problem you believe stuff like slovakia being occupied during WW2 as suggested in "real story" movie you've praised in the movie thread. The same "real story" completely misses to address the domino effect caused by silly assassination. As it usually happen, the idea was not dead, it got fed even more. Or as some would say, after one chopped, hydra grew two new heads.
You can't accept a mockery on people who believe in "real story" movies, aka yourself, okay, you're not the first such person who can't believe stuff they dislike are real life matter.
Life ain't peachy and people are rotten - it's something you refuse to believe because of living under your own imaginary bell of glass where everything behaves only in ways you like not as it actually should.
Grab a rifle and go Afghanistan for a few months. Prepare for PTSD - it instahits everyone who believes all people are Hollywood dogooders.
