The Godfather 1
MICHAEL: How bad do you think it's gonna be?
CLEMENZA: Pretty *******bad. Probably all the other Families will line up against us. That's alright...this things gotta happen every five years or so...ten years helps to get rid of the bad blood. Been ten years since the last one. You know you got to stop them at the beginning, like they should have stopped Hitler at Munich, They should've never let him get away with that. They were just asking for big trouble.
Change Munich to Helsinki.
That should give you an idea "how such a thing could (eventually) happen."
Just a matter of your farce's "there are fine people on both sides" continually allowed its extreme (Trump doing a test run of his later groveling at Putin's feet, months earlier, during the Charlottesville incident).
