Most US oil and gas comes out of private land.
Before the current US government got their mitts on policy gas was cheap. Change that government and it will again be cheap. Do not condemn the US to hell because you are unhappy about the last five minutes, historically.
Russia however cannot change. Their system is locked in, no matter who is on top.
The big push of the last ten years more or less, has been about insourcing.
The “last five minutes” of this country, as you put it, has occurred in many countries. Those same last five minutes of Russian history, before their revolution, resulted in decades of brutal communism, followed by the oligarchy that you despise so much now. The last five minutes of Germany before the Nazi take over resulted in World War II, and would still be a mess if they hadn’t lost the war. The last five minutes of Rome resulted in the death of an empire that had lasted hundreds of years. Once certain changes are brought about, they cannot be undone without, shall we say, a major restructuring. The USA has crossed a threshold and is no longer the country it once was, and it cannot be restored without a “major restructuring”.
