Doesn't sound like you have actually been there. Military is a major employer, but in a territory inhabited since 1944 there are generations of people born there who didn't see a reason to live, the same foreign gastarbeiter as in any Russian city, etc. I.e plenty of ordinary people who could be inconvenienced.

I don't think you meant it like that, but Kaliningrad, or Königsberg is inhabited since a bit longer. For example Immanuel Kant lived and taught there.

Obviously. But since the Russian occupation infamously expelled the natives completely, when I talk about “inhabited since 1945” in the context of people living there now, I’m obviously referring to the Russian population.
