Free and fair elections might be a start, held under OSCE auspices, not held under the barrel of a Russian gun. A UN peacekeeping force could have gone in to Eastern Ukraine had there been atrocities committed against ethnic Russians, but once Putin had invaded Crimea his hands were tied and he needed a buffer zone to keep the spoils.
There are free and fair elections already in Crimea. Ukraine have made clear that they would not having a referendum in Crimea. Again, already discussed on the Crimea thread and previously. Here is what you ignore;
"Ukraine's plans have been spelt out by many Official representatives of the Regime. Such as Kyrylo Budanov the Intelligence Chief who recently made the statement below. No secret is made of this intention.
The self determination of the Crimeans is what Russia offer. Ukraine openly offer ethnic cleansing and genocide; “The majority of the radical pro-Russian population, upon the arrival of Ukrainian units in Crimea through any form of advancement, be it offensive or otherwise, will promptly depart for the Russian Federation via the ferry crossing,” Budanov believes.
“No one will remain here. They will vacate this territory — they are not suicidal, believe me,” he said.
It is not open to any other interpretation, Budanov is openly threatening genocide of "pro Russian Crimeans". To be "pro Russian" in A Ukrainian controlled Crimea would be "suicidal". This would also apply to "pro Russian" Tatars, by the way."
Whether you like to admit it or not, there is no dispute in Crimea to settle. The Ukrainians who claim ownership are fully aware that the Crimeans don't want to be part of Ukraine and never have. You are just blinded by Russia hatred and it shows in your incoherence. You cannot lay out a legitimate claim to Crimea from either Ukraine or from some alleged Tatar diaspora demanding right of return. You are just certain that it can't be Russian.
