Physically we can isolate our adversaries by severing their communications with outside world as well as by severing their internal communications to one another….
Morally our adversaries isolate themselves when they visibly improve their well-being to the detriment of others… by violating codes of conduct or behavior patterns that they profess to uphold or others expect them to uphold….
Such contradictions within ourselves “destroy our internal harmony” and “paralyze us.”
–John Boyd, “The Strategic Game of ? and ?” (1987).
