Speaking to RFE/RL's Ukrainian Service just over a week before his death, Muzychko spoke angrily about the government's failure to prevent Russia's annexation of Crimea. "The authorities should have ordered mobilization and put the military on high alert a long time ago because our country is being occupied now," he said. "Foreign troops are occupying parts of our country. They have occupied Crimea and are provoking our troops. Special [foreign] military units and saboteurs are operating throughout Crimea."

He was right. RS in general is based.

And there was never a single war in history when collaborators haven't been targeted. Here in Poland we killed thousands of them in assassinations during WWII (under occupation). There were special dedicated units just for this purpose.
