Stupidity doesn't come cheap!
Russian gas enters into Ukraine from where it is channeled to other European countries, yet Ukraine will not take advantage of a deal it has with Russia to be supplied the gas for its people's needs directly from the source, preferring to purchase this very same gas from third countries at an additional cost of 35-40 million dollars a month!
Russia does not sell any less gas because of this Ukrainian "strategy", just makes more money for it.
