Yes, it shows that the Russians are losing their patience. But it doesn't negate the restraint the Russians had displayed up until this incident. As it was inevitable that this would happen at some point. War is an ugly thing. I pray it doesn't escalate and it is only an isolated incident by overzealous Russian commanders whose soldiers are dying. Because Russian soldiers are dying so eventually they will up the ante. All because the west wants to subjugate Russia as they've been wanting to since the end of WWII. American desire for hegemony over the world exists even though the western media never admit that. That's why we are at odds with countries like Russia and China. The cold war never ended my friend, it goes on.
We define "restraint" differently, but perhaps the coming weeks will clarify on that.
I can't really speak for what the West wants, but I would guess most Americans just favor fledgling democracies (like Ukraine) being left to fledge in peace, and are not preoccupied with subjugation of Russia. If we were keen on that, I think the Crimean takeover a few years back would have provoked more response than it did.
It's hard to tell sometimes who genuinely wants to nurture democracy and who just uses that as code talk for American hegemony. It depends on who you talk to.
