Actually, one could argue that the German strategy on natural gas was VERY SMART - they had a VERY CHEAP and very reliable source of gas and could still have it today - whereas US LNG would have to be purchased on the spot market, after bidding against China and all other countries that wanted it. With their very cheap and reliable gas, Germany became possibly the wealthiest non-energy-rich country in the world.
Obviously where it went off the rails was when Germany let the Neocons run their foreign policy and told them to ‘punish’ Russia for liberating* Ukraine, where Germany and most of Europe was in NO POSITION to do such.
*I use the term ‘liberating’ to tweak the Neocons...reminds them of their Communist past
Liberating?
