Russian irregular forces have started seizing Ukraine military bases in the Crimea.

Putin is completely right when he says that Western leaders are hypocrites, and that countries such as the US have acted in ways similar to what they are now criticizing.

But if that is meant to justify his actions, that's where his logic is invalid. It is wrong to stir up militias to seize territory, to censor the media, to run unfair (effectively rigged) elections. Those are wrong when done by others, and wrong when done by Putin.
