I would like to think that WWII was worth it for us to come to the aid of Europe. But our staying there and defending them for decades not so much.
Having lived a decade in Germanic Europe it is shocking to see how Germany has become. The generation (s) growing up under the Cold War really had a messed up time and this seems to be the pendulum swing. Both those “red hippies” and the politically correct German youth today are absolutely among the most easily swayed people on this earth.
