Wow, just wow. And how exactly were they supposed to do that?
The unity government was declared on 24th February and was formally convened on 27th February 2014.
How long did Russia wait to see if the new government would accept regional referendums?
Well, Russian forces seized control of key strategic sites across Crimea on, er, 27th February 2014. The same day the new government formed. The idea that genuine free and fair regional referendums were ever an option, or even something Russia had any interest in pursuing or allowing whatsoever, is pure fiction.
Suppose the regions did hold referendums and chose to stay part of Ukraine, do you think that would have been the end of it? Russia would have just backed off and respected Ukrainian sovereignty? That's just not how the Russian leadership thinks. Putin had no interest in allowing even the possibility of any such thing.
Peacekeepers should be sent to carry that out (e.g. from the UN directly).
But dragging out open war like this is just terrible for everyone.
In the first months of the war hundreds of thousands of Ukrainians returned to their country to sign up to fight. We either support them, or abandon them to their fate. I don't see how you can credibly claim that abandoning them, despite their appeals for support, is better for them and in their interests. It's clearly in the interests of the Russian government, but why should the west care about that?
Sending UN peace keepers is a nice idea, but unfortunately Russia is a permanent member of the UN security council, with a veto.
And how would that happen when Russia can just veto the UN action?
The internationally managed referendums Russia has never asked for and would never permit?
Arguments that "real issue" with Russia repeatedly invading its smaller neighbours is that one of the neighbours won't grant something never asked for are not made in good faith.
It's reasonable to assume if we fail to stop Russians in Ukraine, they continue restoring Russian empire with military force.
In the past, Baltic states and Poland were part of Russia, yet now all of them are NATO member states. A real opportunity to start a nuclear WW3.
Yes you are. If you really think you aren't, you are deluded.
Even if Ukraine "wins"? Then what?
What happens to the Russians in the Crimea? Do they just let Right Sector and the Azov Battalion carry out their persecution, and move Ukrainians in just like the RSFSR did to the Tatars?
Likewise how do they control the DPR and LPR? They previously elected Yanukovych, the problem isn't just going to disappear.
But what do you do now? You can't just get the Tatars back, even if Crimea were made independent.
That's been going... Swimmingly for everyone involved. No violation of human rights, whatsoever.
And before Russification it was Tatars, so either way it is Russian like e.g. India or Japan.
It had been independent / Tatar before, and Russification meant it was mainly populated by Russians.
The issue is that Ukraine refuses to allow for the self-determination of the Crimea and Donbass since Euromaidan. Why can't they just allow internationally managed referendums to take place? This would be far better than warfare and paramilitary killings, etc. for both sides.
