why do you think he rejected it? greater integration meant NATO bases. And this guy knew (because putin and russia always said it) that NATO next to russia was a big no go. the next logical steps are easy to understand. europe and USA backing protesters meant that if russia did not act they would be NATO bases next to them. fair elections should have happened and people should have voted for yes/no they want to join europe. then putin wouldn't have been able to attack Ukraine. Instead USA just used their old playbook like they did in middle east
