Except that for the case of WWII... we weren’t breaking *OUR* windows, but someone else’s.
Who then had to buy from *OUR* ready-made window shop a replacement window, because their own supplier was bombed out of existence. Of course, we lent him the money to do it, but we charged interest on that, as well.
It helped us quite a bit, after the war.
its certainly OUR windows. It makes no difference if its in another country. Resources used to replace broken windows in another planet, means less resources for stuff to build in our own country
