Horrible boss
This will force Europe, the US, and others to take energy independence and renewable/alternative energy more seriously as a security concern. It will likely drive more money into research for renewables, nuclear, and other energy sources that are less dependent on Russia or the Middle East.
In terms of defense spending, the US spends outrageous amounts, but a sizable portion of this is because the US is at the bleeding edge of military technology, which drives up the costs (not to mention greedy defense contractors). Adding more Germans to military research and development will improve results and potentially lead to more competition and hopefully less cost for advanced technology.
You are right in that the US spends an outrageous amount. The UK outspent Russia last year 65bn to 61bn. China by contrast spent 139bn. The US? 783bn. How much of that goes to things like DARPA I have no idea.
