A prediction

All those people who are so happy that the comparatgively mildly corrupt democratically elected government of Ukraine has been forced out by violent right-wing thuggery will not ever admit they backed the wrong horse even after the right wing thugs continue to behave in criminal fashion as they hold on to their illegitimately-gained power. As time goes on, they will quietly stop calling them the heroes of the Ukraine spring and gradually start wringing their hands over the "growing pains of democracy" in Ukraine.

At some point they will acknowledge the corruption and viciousness embedded in the Ukrainian right-wing and call the coup d'etat by its name, but when they do that, they will also identify some other gang of criminals as their new heroes.
