Supply and demand, automatically, is the answer. If you mess with natural supply and demand by trying to control it, you will only mess everything up.
The Ukraine war is a good example of this. The US and Europe tried to sanction Russia into pain and problems. It only increased Russia's fair trade elsewhere.

But the US and Europe managed to sanction Russia into pain and problems. The thing is, Europe also sanctioned itself in the process.
Every country has pain and problems in some ways.
Russia has expanded and grown into other parts of the world because of the sanctions. Sure, it was troublesome for them to do this in some ways. But the overall effect is that they are growing and expanding rather than declining. And when Europe finally has exhausted their supplies, they will go back to Russia.
On the other hand, look at the problems Europe is having due to the sanctions. And inflation in the US threatens the very banking system that pushed the sanctions into place.
