As a Czech who absolutely hates the Protectorate era, I can still see a good case to use somewhat neutral expressions like "politically unstable" if you want to discuss technical topics like supply chains without delving into the underlying politics.
Declaring "I am a friend of democracies threatened by totalitarian countries" before every economic utterance looks as performative and ultimately counterproductive to me as all the "land acknowledgments" that infected the US academia. (Not coincidentally, those don't help actual Amerindians at all.)
Yeah, Central Europe in the 1930s was politically unstable, no way around it. And it wasn't just question of Czechoslovakia vs. Germany either. Most countries had irredentist movements and/or land demands on their neighbours.
So, let's say the TSMC is the modern equivalent in "supply chain" terms as Czech guns made in Plzeň, like the Škoda 75mm cannon - wait, let's rewind. I'm not saying Czechoslovakia was politically stable in 1939. I'm saying that when your neighbor claims they need to rescue you from instability - like when America says they need to rescue a Latin American or Middle Eastern country from "political instability" when that country elects someone who doesn't want the country's resources owned and run by companies with imperialist backing - that is code for a green light to conquer them and take their resources. The same as it was for the Germans. The same as it is for China re: Taiwan and Russia re: all the former Soviet republics. Declaring your neighbor "politically unstable" and presenting yourself as its savior was the clearest way in the 20th Century to declare war without any casus belli. I'm sure you wouldn't like your country to be invaded again if the powers around it decide you can't manage your own affairs.
[edit] I also spent about a year living in Prague and I love your country, Czechs are the best, and their sense of freedom is an immense relief from let's say other countries in the EU, so, I think it's amazing that you have maintained your independence from the enormous forces surrounding you and pulling in all directions. I think part of this is something I observed, that Czechs act like they are part of one small family.
