Totally superficial and incorrect analysis. Obama / “The West” / NWO were in fact highly ineffective in managing the currents in Ukraine. About like me trying to affect a major Ohio River flood by sticking my hand in it. Which currents were NOT pro-Russia. Among the people they were anti-corruption and increasingly leaning pro-EU (mainly to rid the worst of the corruption.) Plus, Ukrainians, esp. the under 40 crowd, could easily see their EU neighbors were doing better than Ukraine, despite Ukraine’s enormous resources. Yanukovych was corrupt as hell. Even his own Party eventually helped throw him out.
(May Biden and Pooty suffer the same fate.)
His party didn't 'turn against him'. Those that didn't manage to flee were under the thumb of the coup regime and didn't want their legs broken.
The pro-EU Maidan protestors were the pretext for the coup. Right Sector & Svoboda - who actually carried out the coup - had no interest in joining the EU. The Ukraine they prefer to live in could never pass the anti-corruption requirements. Now - after eight years - the Ukraine is no closer to joining the EU than landing on the moon.
Once the coup went in: Obama's WhiteHouse made sure that US Aid money - laundered through Kolomoisky's Privatbank - was used to fund the proxy war in Donbass. This isn't your hand in a stream Brother - but men, missiles, tanks and artillery.
Remember that the Svoboda party had only about 8% of the seats in the Rada, but mysteriously held a whopping third of the coup government’s 18-member cabinet.
This included the posts of Deputy President, Minister of Defence and Prosecutor-General. That's the state monopoly of force right there. With enough billions in redirected Aid - and later, direct 'lethal Aid' - the Donbass war that they began could theoretically have gone on for ever.
