He was mentally disturbed, which kinda proves the point. After returning to Germany, he stabbed a woman for rejecting his advances. Later, he was convicted of shoplifting, and a few years after that he was convicted again of selling stolen goods.
Definitely a "character", even if medically sound enough to stand trial.
I'm not sure any countries really shoot down light aircraft unless it's an active war zone. They are not much of a threat and it's also hard to tell if they are there legally or not.
This was the soviet union in a very tense time. If he hadn't been shot down he would have been forced down. But yes that would have been a more likely outcome, true.
PS: Don't forget the Soviets knowingly shot and killed an entire airliner full of people. I saw an interview with the fighter pilot later and he didn't even have remorse for what he was doing, "just following orders". What a monster. But that was pretty typical there. Anyone with a backbone questioning orders was already dying in a gulag.
If I were in the US I would certainly leave to a more socialist country. I could not live there. Even before Trump.
However there is a spectrum between it. I don't think either extreme is great, neither American unrestricted capitalism nor full-on communism. A balance of both is needed. I was a lot happier in the 80s when Holland was a lot more socialist. Less things to worry about, a safety net, cheap housing and schooling, still the ability to run your own business if you really wanted to. We had a great combination.
However the VVD neoliberals (who idolize America) have destroyed it over the last decades and there are so many huge problems now because they always went for the quick fix.
With full-on capitalism you get lots of disenfranchised people angry at not having any upward mobility, corporations just dump all over the citizens, and differences in wealth get insanely high. With full-on communism you end up with a surveillance hellscape and inhumane processes. The secret sauce is in between IMO.
