Re: Did Sisko ever break the Prime Directive?
Sisko told Worf to... do whatever it takes. Come on... what do you expect him to do? Previously both Picard -and- Sisko had reprimanded Worf for putting his Klingon culture over his behavior as a Starfleet officer... so you can't have it both ways. If Sisko can reprimand Worf for trying to kill his brother at his own request... he can't go back on that and say oh.. well do your Klingon thing now and kill Gowron. Not without being hypocritical anyways... but hey, war brings out the worst in people.
