re: #58 Anymouse
When my wife and I were in Poland Russia was already building up its armed forces in the Kaliningrad Exclave and had banned land border crossings by Americans (not that we wanted to go there).
They have been building up their forces even more since then.
Defensive measures. But just as no one will realistically occupy Kaliningrad, no one will realistically occupy Poland. Such suggestions betray somewhat of a naive view of the whole situation, without an understanding of why and what gets invaded. If you think about the reasons for, e.g., the Ukrainian invasion, the logistics of it as well as the long-term consequences of it for just a minute, such scenarios should become obviously fantastical.
So let’s not get paranoid and carried away: countries like Poland, Finland, Czech Republic or Sweden won’t get invaded any time soon. Neither will the Baltics. The danger zones are non-NATO members with large Russian-speaking populations. Because they’re the only ones that can be sustainably occupied by Russia in long term, and that only if the population is half-willing (see Ukraine, Abkhazia, South Ossetia, Transnistria… the latter three not still not formally annexed BTW, despite being the earliest conflict zones).
