Yes they did. They relied on them for the attempted ethnic cleansing in the East as well. Perhaps they have outlived their usefulness in this sickening Soros/Obama/Neocon putsch.
What do you mean by ethnic cleansing in the east of Ukraine. The only people being ethnically cleansed there are ethnic Ukrainians. The Ukrainian nationalists are not against the Russian speaking people, many of them are Russian speaking. They are for the independent and territorially integral Ukrain. And, yes, they are against Putin’s aggression.
