The best solution right now is to end NS pipeline, end our reliance on Russian gas, and cut the oligarchs legs off that control the Russian elite. The last obstacle would be the military-industrial complex there, but if they want to lose their marbles and carry on a hot war, it will be a much bigger humiliation that the end of the Cold War.
Russian gas is 2x cheaper than American LNG (and not to mention much cleaner), so no, I want the money staying in the pockets of European citizens.
Once America stops buying Saudi oil and supplying them with weapons, we can talk about switching over to a more expensive Gas alternative just to "stick it to the Russians".
The EU imports more than twice as much Saudi oil as does the U.S.
Both are fairly insignificant compared to China, India, and other Asian countries as buyers of Saudi oil.
As for the U.S. being Saudi's military supplier, it gets plenty of assistance from the EU in supplying the Saudis. The standard Saudi Army rifle is the German H&K G3.
In addition to the F15, the Saudis have plenty of Typhoons and Tornados in their air force.
The Saudi Navy is at present a mixture of French and US equipment, primarily French, and is currently acquiring Spanish corvettes and German patrol boats.
So it's pretty clear that if Europeans want to castigate the U.S. for Saudi arms sales, they've got some things to do first if they don't want to be hypocrites.
