Watch Winter on Fire. The idea that the Maidan was a US managed coup like Chile in 1973 or Guatemala and Iran in 1954 and 1953 is fantasy. Tim Snyder's Yale class #20: https://www.youtube.com/watch?v=Gg_CLI3xY58

Russia's ambition to crush an independent Ukrainian identity and the bottom up idea of contractual governance is three centuries old, which you'd know if you bothered to listen to Peter, Catherine and the language and media banning Alexanders and Nicholases. It's Russia's resource-cursed land-based colonial empire that's contingent, negotiable and prone to repeated collapses since 1917, not Ukraine. The fundamental problem is the gap between Russian geopolitical ambition to parity with the West and its real state capacity as a third world petrol station. This is what drives Russia's collective narcissistic nationalism and autocracy-generating marriage to empire, whether under Tsars, Bolsheviks or post-Soviet mafia with a flag kleptocracy.
