Crimea was never Ukrainian in the first place.
88% of the population is Russian or Russophones, 98% speak Russian.
Guess where is Yalta situated?
In Crimea, for god’s sake!
Crimea is Ukrainian now. Regardless of the past, it is currently now part of Ukraine. That most of Crimeans are ethnically Russian doesn’t give Russia the right to invade with troops. Like I said before, that line of reasoning is wrong. It would mean that Mexico has the right to roll troops into the U.S. southwest because the majority there are hispanic. See? It doesn’t work that way.
And your point is?
