And you may be interested to know what kind of government Taiwanese had until 1987(, as well as Hong-Kong before 1984), or not, i'm just saying. Bye :)

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.

She wasn't simply not invited anymore is she ?

Hum, they liberated them from nazi Germany ? Are you talking about the Warsaw Pact ?
Still angry at Yugoslavia for not supporting more actively the greek communists, you know which side the "free world" was on in the greek case(, and you can bet that the soviets wouldn't have let Franco stay in power if their victory wasn't stolen).
If you're saying that they installed puppet governments, why can't i say that the u.s.a. installed puppet governments in western Europe after they prevented the u.s.s.r. from liberating the rest of Europe from rentier capitalism ?

They had their share, but it's at the very least 10 times less, certainly even more, than the west. Do you have some examples in mind ?
However yes, they supported what they called the "liberation movement" from the "exploitative bourgeoisie", and failed almost every time once the west reacted. They didn't thought about it as defending their own interests, but acting in solidarity with other workers.
If you're talking about Afghanistan then they had the support of the government, just like France in Mali a few years ago(, who kept putting forward this argument in the malian case, but almost certainly ignored it with afghans)(, in any case afghans hate the west as well now, it's one of my favourite countries, pledging to become islamic/virtuous, critised for being too different and allegedly immoral).

The examples are almost endless, but it's worth noting that it was revealed two days ago that the west supported Imran Khan's arrest, thousands of kilometers from our borders. Do you know how the u.s.a.(, and western Europe really,) was called in my highscool ? The policemen of the world. What seemed like a harsh criticism was in fact a dull euphemism.

Just saw this today (source if you have an hour to lose) :

B.t.w., here's the article, but we should still be wary of the statistics, one of them is in current prices while the other is in p.p.p.
Furthermore, i'm not sure that the g.d.p. is the best way to estimate the economic power of a state, there may be biases if, e.g., a capitalist economy leads to an artificial augmentation through the different capitalistic rents, i.d.k.
Even by these standards, the u.s.s.r. did better than the ex-colonies (source) and most of the world , despite having a more democratic workplace, better working conditions, sanctions, ..., and military is such a waste of money while we could unite, and use this money for so much more.
I've seen that germans are quite active here, as well as on reddit, frenchs only arrive third as non-english speakers, it's a bit weird not to hear more about Spain&Portugal or Italy, 🤷‍♂️
I'd say that i'm french but i.d.k. if i'm entirely identifying with my country anymore, what's certain is that i'm identifying with the classic(pre-XIXth) authors of western Europe, may i ask why you were happy that Berlin had to be excluded :) ?
