I don’t feel bad for Putin but I do agree with him that the US and other Western groups have plenty of blame for the current conflict. Putin didn’t just wake up one fine day and start moving troops towards the Ukrainian border. It was a response to NATO troops moving closer to his borders and talk of Ukraine joining NATO etc.
He is 100% correct for saying that if Warsaw Pact was still around and there was talk of Mexico joining the Warsaw Pact along with Warsaw Pact troops moving into Mexico the US would not just ignore it. (Nor should they)
