That's incredibly naive, if you excuse me saying so. 300 million people depend on Russian gas supplies, yes, most EU countries have emergency supplies for few weeks in case of a major disruption, but those are for emergencies - not for threats of "do X or else".
And those reserves (not even for emergencies, just to stabilize supply) have not been replenished since last year's severe winter, causing gas prices to spike in the past few months.
