They should pay for Crimea by the square foot. It actually belongs to the Crimeans
(Germanic Goths, then turkic tribes, IIRC)
The last time I was in Sevastopal (2013), the inhabitants were pretty much exclusively Russians.
Crimean population by religion: A survey of residents of the Autonomous Republic of Crimea in May 2013 found that: 58% Orthodox; 15% Muslim.
