WHAT ?
Oh man, it is the number one "policeman" by far. Here's an example :
Here's a longer list if you're interested : https://github.com/dessalines/essays/blob/master/us_atrocities.md
Here's a source from the congress itself, even if it doesn't include covert/unofficial operations it's still quite lengthy : https://crsreports.congress.gov/product/details?prodcode=R42738
I.d.k., what more proofs do you want ?
And were you still talking about Poland, Czechoslovakia and Hungary in your last comment ? Because they weren't in the u.s.s.r. but in a military/.. alliance, like n.a.t.o., the e.u., or the c.i.s. Is it because their republics were different than ours ? It'd be another talk then.
Yeah i know(, that it's a "far"-right political party(, not nazi, or else it's hidden)), people dissatisfied with the current situation are voting either "extreme"-right or "extreme"-left, because what they understand the most is that they want to experiment a new situation, hoping that it will be better than the current one, the famous "protest vote". That's why poor people are voting far-right against their own interests, as if it'd solve their socio-economic problems(, i'm obviously biased in this assessment).
As a german, you already know that communism was very popular in Germany during the 20s(, Marx&Engels came from there after all), and that nazis were fighting them in the street, there were deaths every week between them. Capitalist's medias saw the growing popular disdain for the center and took an easy choice.
