These guys have not understood yet that Putin does not bluff.
Like I said here before, Russia has Europe's largest natural gas storage facilities. And since winter is mostly over they should be fairly empty. Russia can easily stop supplying Europe with gas and start filling their own storage. And if the Europeans insist on not buying for a month or two, the Russians will just start progressively shutting down gas wells. And in the future Europe might find out they won't be able to buy any gas from Russia in the short term. As the gas wells will take months to become operational again. By that time winter in the Northern Hemisphere will come and good luck getting gas anywhere.
When you see them claim that a large fraction of Russia's government income is from oil&gas sales they get mistaken on several counts. They confuse all mineral taxes with oil&gas taxes. They forget Russia consumes more gas than they export. Etc.
Russia produced 762 bcm of gas in 2021. They exported 169 bcm to the EU. 10 bcm of piped gas to China. So who do you think is getting most of the gas? Russian consumers. They are the ones paying most of the mineral tax.
Also for reference the EU's "huge deal" to get 15 bcm of LNG from the US doesn't even replace Russian LNG imports by Europe. Let alone piped gas imports.
