So that's why

I've been on about Russia pushing to control oil flow to Europe. Now there's an excellent explanation for the most recent battle with Ukraine:
The War was instigated by Putin and Russian President Dmitry Medvedev who decided that the time was ripe to discredit Ukraine in the eyes of European leaders by launching a huge public relations and disinformation campaign to convince the EU that Ukraine was an “unreliable transit country.” By turning off the gas spigot to Europe on January7 and blaming this on the Ukrainians, Moscow began systematically blackmailing Europe into supporting Russia’s plans to build the North Stream and South Stream pipelines. This argument became the central theme at press conferences by Putin and Deputy CEO of Gazprom Alexander Medvedev during the Gas War (see www.gazpromukrainefacts.com, the Gazprom website designed to discredit Ukraine).
