Then why are they in the Middle East, never mind the Crimea affair?
The Bible does not say in vain that leopards do not change their spots (from Jeremiah 13:23).
Crimea is a complex affair I agree but it made no sense for it to be a part of Ukraine. US foreign policy generally supports the right of people to self-determination and it is the cleanest example. Nobody would reasonably argue that the vast majority of Crimeans support Russian administration.
As for Middle East I don’t see Russia invaded anyone.
