The accord would have more closely integrated political and economic ties between the EU and Ukraine. As popular protests mounted at Yanukovych's betrayal, he cracked down by attempting to ban demonstrations and to arrest the leaders. The result was that Yanukovych was forced out of office and fled to Russia when the Ukrainian military and police refused to obey his orders.
How is the West to blame for the thuggish stupidity of Russia and their Ukrainian puppet, Yanukovych, that led to his ouster from office? Or for his massive corruption? Or for conflicts between pro-Russian and pro-Western Ukrainians, with Russia fomenting clashes and using them as an excuse to carve off slices of Ukraine? Or for the Russian invasion and Putin's plan to install Yanukovych as their puppet Ukrainian president?
Logic and facts rarely enter into Russian propaganda claims. Notably, when Russia invaded, even ethnic Russian speakers in Ukraine shunned them. There is a vast difference between wanting better treatment from your government and wanting to experience an invasion and overthrow of that government by a brutal neighbor. When Ukraine wins and Russia is forced out, my surmise is that Ukrainians will celebrate, even Russian speaking Ukrainians.
You are pretending it was a popular uprising that disposed of Yanukovych, but it wasn’t, special ops were trained (presumedly by the US/NATO) in Poland for that purpose (the sharp shooters, ect). This was confirmed to me by a member of the Polish military at the time it was happening. This was no organic spontaneous uprising of the people to get rid of him.
