How long before Putin decides to move in to 'protect' Russian-native citizens of Eastern Ukraine? We need to enforce some sanctions that will actually stick otherwise this is going to be Russia's modus operandi for the next decade. Incite disturbance, move in to calm things, call a urgent and immediate referendum and a new member has joined the Soviet Un...I mean the Russian Federation. 
Reminds me of this bit of Yes, Prime Minister:

The only positive sign is that China allowed the UN Security Council to vote against Russia. It would appear that Russia is risking isolation with their antics and if that's what Putin wants then so be it. Better than having Europe dance to his dictatorial tune. It's still shameful that we were left powerless over the assassination of a dissident on British soil.
