Thank you, that was really interesting.
As for should Ukraine control the Crimea? Shouldn't the people who live there be given the option to a, stay with Ukraine, b, become an independent state, c, become a part of Russia.
That's what happened in Timor-Leste... (Mind you, they were invaded by Indonesia in the 70's). The people of East Timor went to the polls, and voted to remove the local government control from Indonesia and reform as an independent state (with the help of Australia and the UN). Shouldn't the people in the Crimea be given the choice?
PS. Not trying to turn this into a political discussion.
