You started paying for it back when russia was just starting to recover from the fall of the soviet union. Nowdays russia surely has enough money, but if you are stupid enough to keep paying then I dont se why they should stop recievingNo one ever turnes down money.
On the other hand, america has got plenty of dirt cheap uranium from russia from the megatons to megawatts program. So a quite large fraction of your electricity comes from dismantled russian nukes, that evens it out a bit.
