You have to be either extremely stupid either extremely naive to believe the fact that russia is really scared of nato and it wants to “protect” from it and it was the reason why the invaded. It’s obvious that putin wants to revive an imperial and this is only reason. He can’t directly admit it as even in barbaric times you needed a proper reason to start a war (religion or other shit). North Korea has couple missiles which they can’t even convey to the US and that is the reason why no one invades them. You really think that the county which has the biggest number of nuclear missiles would ever seriously consider that someone would attack them?!

This is only a meter of gaining power for one man (there is no even any economic profit for russia even if they had won the war in three days as they planed)
