As a user living in Norway, I can say that nothing has changed yet and Meta still does whatever the fuck they want. I use it Facebook from time to time and Facebook still shows me ads related to what I do in an out of Facebook. Even when I use adblockers in all my devices and alternative search engines like Duckduckgo or Ecosia, they still know what are my new interests in and out of facebook and keep showing me personalized ads. I even disabled within facebook to track me outside of facebook. Nothing works for them.

I recommend you to review your sources: before the start of the WWII, Stalin and Hitler signed an agreement so each could invade their own countries without interfering each other (Molotov-Ribbentrop Pact). Both sides were doing the same thing from each their side until Hitler broke the Pact by trying to invade Russia. Only then Stalin begun fighting the nazis as you claim.

Edit: to add a last phrase to conclude my argument.

Because of history: Hitler started in the same way attacking Poland, and also Stalin did the same from the East (started with Poland too, and then proceeded to try to take Finland).
