It's so funny watching you just regurgitating the offical narrative.

Funny, it is your sentence about "US warned Russia, but Russia didn't take it seriously", not mine all over MSM articles and social shitworks posts actively created by thousands by paid imbeciles like NAFO and Hasbara. So who is spreading "official narrative"? :)

You didn't answer question. What exactly Putin had to do, to satisfy your understanding of taking US "warning" seriously?

Write it. You state that Putin did everything wrong. OK, he do many things wrong. What exactly he had to do to to make everything right?
