Putin wanted the US to walk away from his insane demands so his propaganda could then blame the invasion on “America’s rejection of negotiations”. And invade he will. Putin wants to invade, occupy, annex and enslave Ukraine, and then russify its people, with all the terror, torture, murder and genocide such a policy entails.
He is definitely a chess player. His original plan was Trump would still be president and as Mike Flynn has pretty much admitted, they would have supported Putin’s move into Ukraine. It would have been repayment for all the money Russia spent to get Trump elected.
