The actual solution for European countries is for them to find their own sources of gas, which in most of them are already below their feet. Poland, Ukraine, and UK, for instance, have extensive shale gas fields.
Ya. IMHO, poor planning has put them in a bind. It takes years to develop those sources.
Much like our attitudes towards energy here in the States. And like Europe, we may be stuck in a bind in a few years and be beholden to our enemies.
Maybe we can treat Europe’s situation as a teaching moment. Then again, maybe not.
