All of that, just to not buy Russian gas. The dumbest part I think from all of their posturing is they'll likely just buy the Russian gas from a third-party or quietly transition back to buying them after the whole situation cools down. Its not enough that they are supplied with gas, it has to be economical and at large quantities to keep their industries running competitively and inflation low.
I think their idea, well, the Visegrad group idea, pushed by some people in the US, is to ring fence Russia with a broad coalition of former Warsaw Pact countries now in NATO. Those would be pumped full of weapons and basically cause Russia to go into a massive conventional arms race just to keep up. That is why Poland, and other nations in Europe, started breaking the Conventional Forces in Europe treaty. These countries would also have bases in the Baltic and Black Sea and contest the Russian Navy there. Threatening to block Russia's main import/export ports. Poland would use incomes on transit through the Yamal pipeline to fund their own rearmament program. Ukraine would do the same with their pipeline. Basically Germany and Italy and other nations in the EU would be paying Russia to pay Poland and Ukraine to arm themselves against Russia. Sounds almost as good as the Trump plan to build a wall with Mexico and making Mexico pay for the wall no? Except Russia and Germany built the NordStream pipeline, Russia and Turkey built the TurkStream pipeline, and put a kibosh on those plans by bypassing both Poland and Ukraine. Oops.
NordStream has 60bcm capacity and NordStream 2 doubles that. TurkStream has 30bcm capacity. Total gas exports of Russia to Europe and Turkey last year were 155bcm. So, you can easily cover that with the capacity of those pipelines. Now, that is not near enough to cover total European capacity in a non-COVID 19 depressed economy standard. And in an economy where the gas fields in the North Sea and the Netherlands are winding down. But should be enough to keep Europe at the COVID-19 economic standard. If Germany does not want to license NordStream 2 after, what I think, will be inevitable closing down by the Poles of Yamal pipeline, and maybe the Ukrainians of their pipelines. Then that is their problem.
