Any alternative with supplies will cost a lot more due to logistical problems. Therefore, a more likely scenario is the purchase of Russian gas in other countries, and according to documents, it will not come from Russia.
I don't think so - because of the same logistical problems. In order to resell Russian gas to the European Union in a democratic package, the intermediary must have some kind of surplus, and no one has such surplus now. Hungary recently agreed with Gazprom on additional gas supplies in the amount of several million cubic meters per day, which will come through the Turkish Stream - and this is perhaps all that the European Union can count on.
