Considering that Crimea is 90% RUSSIAN, just who should administer it, other than Russia?
Just deport the ethnic Russians back home. Turnabout is fair play.
The rus are home. They even once tried to sack Constantinople from there.
Just where do you live, sir, and what happened to its prior inhabitants?
I sense affinity for 'fair play' to be a fleeting thing...
Considering how many centuries the Crimea was Russian before the Communists handed it to the Ukraine in 1954 (without getting the consent of the populace), what you wrote sounds about as reasonable as saying all white Americans should just go "home" to Europe.
They are home - they’ve always lived there.
