They can also see the contrast with next-door Russia. The Ukraine is one of the poorest countries in Europe.

The overthrow of the government was effected by armed militias, with a heavy far-right presence (e.g., pictures of Stepan Bandera, the Nazi collaborator who ethnically cleansed Poles from Western Ukraine during WWII). The US government had a hand in picking the successor government - there's even audio of the behind-the-scenes discussions. There was obviously popular support in Western Ukraine for Maidan, but there was also a lot of foreign involvement and the seizure of power itself was violent and unconstitutional.
