When Ukrainians overthrew Putin’s puppet Yanukovych back in 2014?
My personal opinion is that Putin was never negotiating in good faith. He was negotiating as a stalling tactic while prepared and/or waited for the most opportune time to invade.
Yes, I agree, it has never been in good faith. Putin is a fascist, in the true sense of the world. His ideology is based on a "natural order" in which the strong dominate the weak and a past dream of lost glory. When he's using the "blood and soil" argument or he's talking about fighting against degeneracy it's not by mistake. If you look a bit at the ideology popular among high-ranked Russian, their behavior for the past 15-20 years make more sense.
