Now that the interim president of Ukraine has sent in the tanks and artillery, and a full-scale civil war has erupted, it’s unlikely that the Ukrainians will be able to vote in a few months, as scheduled, to choose a democratically elected president.
The interim president will declare martial law as the blood flows in the streets, and no elections will take place. The interim president will then become a permanent dictator until he decides to allow Ukraine’s eastern Russian-speaking provinces to choose through referendums whether they want to join Russia or remain in bloody, war-torn Ukraine under a dictator.
The interim president should allow such referendums to go forward now; he should have done so before he allowed the first tank to enter Ukrainian streets. And while the blood is flowing, the natural gas won’t be, as Russia is likely to cut of Ukraine’s supply through pipes that also supply Europe.
You really don't know what you are talking about.
The Ukraine should demand a new referendum in the Crimea scheduled four years from now, and with international observers. Why have only one? The Russian government will make themselves even more unpopular in the Crimea with their world-class bureaucratic incompetence.
They should also send agents to Kaliningrad and agitate for a referendum there. Kaliningrad would be happy to vote to join Germany but they would probably even vote to join Ukraine if that was the only way to get out from under Moscow.
