I completely agree with a part of the comment that DE gov't probably didn't consider a long war or a long bad relation with RU. If they did, there wouldn't have been blocking Spain's proposal to supply EU with Algerian and Moroccan gas. And they would have been looking into incentivizing solar, geothermal, etc. with immediate effect. Since German heavy industry is very dependent on Russian gas, if it's not coming, it's almost guaranteed a global economic meltdown much like 2008. Since it's not coming from banks liquidity this time, we are unprepared for it.
