Well... more along the lines of 'we've been selling this gas duty free for a while, in exchange for that port in Crimea, but since you no longer provide that service, we're no longer waiving the duty fees. Oh, and give us 2.2 billion for the gas you've already received that you still owe us.'
Unfortunately Ukraines “freedom” will always be on the table from one revolution to the next...Russia's already going around Ukraine in the future...and the EU will basically drop the ball overall..and there they will sit.
Ukraine didn't see very far down the road...and they still don't. Same Governing people are running for Pres. as in the past....at most Ukraine will be neutral...with agreements No US missile bases in Ukraine...and the oil MIGHT flow.
