They are still behaving as if Germany is going to invade militarily again *rollseyes*
...or as if they are reading comments about Poland on the German internet! :D
Russians
A lot of their forces are currently bound in Ukraine. Judging by Putin's recent statements they will attempt to solve the "Ukrainian problem" first. Also, they can't weaken Caucasus and Chinese border too much, so that should give us about 4-5 years of relative peace. It might seem like a lot of time, but it isn't. Hence the government spending money like crazy, strenghtening the territorial defence etc.
NATO
If NATO fails to meet their obligations (quite possible with Biden in power and the West full of
Putinverstehers) then we'll be alone again as usual.
That's why we have to:
a) make invading Poland
unprofitable - it's simple economics, question of money: if winning war against Poland will cost more than benefits the invader would get, they won't invade;
*hence the military equipment purchases*b) make Poland
indigestible - if for some reason they invade anyway and, most likely, defeat the professional army, then we need to have underground structures, people ready for partisan warfare, suicide bombers etc. etc.
*hence the emphasis on patriotic education at schools and territorial defence build-up*All in all, for an objective observer, it looks like PiS is preparing for war. Or maybe it's just the case of
si vis pacem para bellum usw.
