Not sure if I understand you correctly Soubig.
Yes, I think Russia had a number of military scenarios for taking Crimea. Obviously. This was very skillfully executed. Obviously they were at least partly following an existing script or a pre-planned approach. The only factor Russia couldn't control was Western Media and the statements of Western media, and sanctions. But if this was a poker game, Russia played the hand it was dealt extremely skillfully, for a prize it really badly wanted. A completely blood-free takeover.

And yes, the way this was done by Russia, was sneaky towards Ukraine. It's understandable that Ukrainians are angry about it.

However I still approve because 1) it was the will of the people in Crimea and 2) Ukraine allowed itself to once again be descend into chaos, and there was a coup d'etat, so the constitution was no longer valid. If Ukraine can't get its act together, then who can blame the Crimeans for searching for stability, better incomes and language guarantees with Russia.
