When there's no form of legitimate governance in the region, yes.
The government held at gunpoint by Right Sector after being smeared by the Western mainstream media for apparently ordering the shooting of civilians had only then decided to impeach Yanukovych, long after he had fled after receiving death threats.
That's the kind of people brought to power in Ukraine, people who hold a gun to peoples heads, murder journalists and send death threats.
Two more BS's, which were hammered into your thick head by RT, LifeNews and some other "relevant and unbiased" channels...
The fact, that presindent was ousted and then got impeached after running away DOES NOT invalidate legally ellected parliament OR the ministers they chose. And Poroshenko was elected by more than 50% of eligible voters, even if 3 regions of Ukraine did not had a full chance to vote. How is that for a legitimacy? I find it MUCH better than Crimea "referendum" or the shams in "novorussia".
Yeah... guns of a fringe right-ist movement, which got like 2 or 3 % votes created a coup. Can I get an address of your dealer? Because the shit you are smoking seems to be good.
