Stopping NATO expansion would be an absurd demand if Russia did not have the power to stop do so by force which is what it’s now doing. Russia gave NATO a choice of either stopping expansion to its borders, or resolving the situation by force. NATO chose to resolve the situation by force. The whole narrative that Putin started the war and nobody else is beyond infantile because it just ignores all the history and geopolitical context pretending as if this was some random event that happened out of the blue and for no logical reason.
NATO has maintained a policy of might makes right since the fall of USSR, it has invaded and razed numerous countries over the past few decades, and now it’s run into a country that will no longer tolerate an aggressive military alliance on its borders.
