I understand perfectly, but precisely cutting off gas to Europe allows Russia to put pressure on it, since it forces Europe to pay these horrendous prices to the US and they cannot get money to support Ukraine. It's an easy game for Russia to send a submarine to put a couple of torpedoes into the pipelines, since they have it patrolling the Baltic and North Sea anyway. Both Russia and the US have plenty of reasons to cut off the tap to the EU, albeit for different reasons. In Spain and Portugal we are luckier as we do not depend on Russian gas, because we have a good infrastructure of our own renewable energy and because we receive gas from Algeria, but the rest of Europe expects a long winter.
