Economic warfare - end game is causing economic harm to the US and its interests. If everyone loses their jobs in the energy industry in the US, that forces the US to buy oil from foreign entities. The US energy industry cannot exist beyond 3-6 months with sub 20 dollar oil prices.
I grew up in an area where oil had been found decades ago. There was mini oil rush and then ... it was discovered to be not as accessible as initially thought. Suddenly the rush was over.
It was a very fast boom and bust.
For a good 20 years I saw bumper stickers that said something like "Please God give us another chance, we won't screw it up this time." It was a very midwestern sort of self blame for a thing that wasn't anyone's fault.
Decades later... they got their shot again and the boom lasted quite a bit longer, until recently.
Once prices rise again it becomes profitable to extract again....and all Russia got were their own losses... and if other nations don't play along, maybe more losses.
Ultimately Russia can't stop the US from having a supply of oil anymore than the US can stop Russia.
