Qatar is one of the major beneficiaries from this war, along with the United States. The EU will end up importing LNG from Qatar and the United States, which will cost them 5x when compared to the pipeline gas from Russia. And this is one of the reasons why the United States is pressuring the EU to stop gas and oil imports from Russia. Americans are planning to significantly increase the gas output and sell them to EU. And producers such as Qatar knows that their super expensive gas will never be able to directly compete with cheap Russian gas. And that is exactly why they are asking for 20-year and 30-year contracts. Once the contracts are signed, Europeans are fucked for ever.
So basically it's usa that is trying to play cold War tactics by not indulging directly with Russia rather try to give economic harms to Russia by pressing EU not to buy oil and gas from Russia. Qatar is known for selling his super expensive LNG to underdeveloped countries by bribing the authorities. I don't think its so easy for Qatar to fool EU and convince them to buy there expensive LNG.
USA is no doubt influencer and tying to poke their nose in every issue. But i do not think that their tricks can be successful here. Russia have so many other option. A lot of other countries in south Asia who need gas can import from Russia. For example India is a new gas and petrol buyer in big quantity. i think that in next days other countries like Pakistan will also import gas and petrol etc from Russia.
