The stupidity of this statement is that the apparent solution is to, again, manipulate Crimea back into a reborn Soviet Union without the free choice of their will being respected. Though, I do not deny that there are many Crimeans who are Pro-Soviet (not to be confused with Pro-Russian).
Most are pro-Russian. So yes, this is their choice, fully consonant with international law and European values.
They’re deciding their own fate, not Moscow, Kiev, Brussels or Washington.
No one else has the right to make that decision for them. Whatever they decide, I respect their choice on democratic and human rights grounds.
No one is denying Ukrainians the right to decide the fate of their country. But they have no more right to deny that choice to the Crimeans than the British had the right to deny it to Americans in 1776.
After all, self determination is a universal principle, even if its one imperfectly realized in our world.
