Much of Germany’s past aggression was primarily intended to obtain reliable sources of fuel. In the past three decades they have invested unimaginable amounts of money in “alternative energy”, the vast majority of these funds went to wind and solar. But wind and solar by nature are not “reliable” enough to power a modern economy. In the end it was more of a feel good exercise, and because for decades they also have a birth rate that has been lower than what it takes to maintain their population, they have had to take in millions of emigrants from third world countries. We have troubles of our own, but Western Europe has created a much bigger mess for themselves.
