Europe should levy a high tariff on Russian energy
Even as russia has invaded Ukraine, terrorised civilians and flattened Mariupol, the European Union has spent €44bn ($46bn) buying its oil and gas. That could be about to change. On April 27th Russia announced that it had stopped supplying gas to Bulgaria and Poland, which had refused its demand to pay in roubles. Because the eu can easily buy oil, but not gas, from elsewhere, Russia is attempting to exploit its point of vulnerability.
