Molotov-Ribbentrop Pact — Moscow divided Poland with Germany (1939), invaded Finland (1939), occupied Baltic States (1940) — for two years of WW2 Moscow was Germany ally. After WW2 Moscow occupied half of Europe for 45 years, countries become free less than 50 years ago. Moscow made North Korea and China regimes, still supports dictatorship across the world, occupies and annexes neighbors.

I don't think Russia has many neighbouring countries it can still invade, because it literally already did all of them (except Norway?). And with their size, they have a lot of neighbours. It's very comfortable to restrict your argument to the last 50 years, but the true story of Russia is completely different.

Even the last 50 results in a silly long list.

Wars involving Russia in the last 50 years must be around 20, and don’t forget the occupation of half of Europe.
