"The basic problem with war is that, whether we are 'the good guys' or 'the bad guys,' it promotes and rationalizes the very worst part of ourselves: we are encouraged to kill and brutalize other human beings. (In one sense -- the most important sense? -- once a war begins there are no good guys or bad guys, just groups of people trying to hurt other groups of people.)  In doing these things to others, though, we also do them to ourselves.  This karma is very simple.  To brutalize another is to brutalize myself--that is, to become the kind of person who brutalizes."
