Sorry, this is not true. Misinformed at best.
Russia has been warning for years that they won't tolerate having another NATO country adjacent to their border.
Every single analysist knew that offering NATO membership to Ukraine would have caused a conflict. And yet we went ahead and offered it.
Without this expansionist step from our side the situation would have never escalated.
This is well documented and confirmed by top notch geopolitical analyst and even NATO officials.
So you want to keep Russia out of a country? Don't offer them the NATO membership.
Why would we expand NATO anyway? It is only an aggressive move and I don't understand why we keep doing it, unless we have an interest in causing conflicts like this one and then polarizing the world into a new cold war.
Check recent history. Who's waging unwarranted wars thousands of miles away from their borders all over the world? It's not Russia, it's us! We are the imperialist here, not them.
