During the days and weeks leading up to Russia's move into Ukraine, the US rhetorized over and over again about Nord Stream. All the time the main issue was that the EU must not buy LNG from Russia, it must agree to USAs "energy dominance" politics and buy LNG from them and only them.
This is a way to make sure that when winter comes, the EU has nowhere to go for LNG but to the US.
It's getting more and more clear that the one major obstacle to true US hegemony is not Russia or China, it's the EU with its strict principles, laws and regulations, and that the US is working hard to wear down this resistance and force the EU into dependence and coerciveness.
