Really? Who is going to “make them pay?” Russia can easily say, “Nordstream II or freeze in the dark. “ Then what?
It will. NSII was built specifically to finish the Ukrainian racket over transit fees and siphoning the gas for their own needs.
The only chance for the Ukrainian transit to continue is if someone (Germans or Biden) agrees to compensate whatever Ukraine steals and transit fees.
If Europe and Biden are serious about having Ukraine in their orbit, they need to do it. Russia is not going to sponsor their clients.
