Of course, Picard has a notoriously broad view of what the PD forbids him to do.
Am I missing something? I just viewed the section in which Gowron's ship is attacked in orbit, and Picard makes no reference to the Prime Directive. He only states non-involvement in internal affairs. I thought that the Prime Directive referred only to primitive (pre-warp) societies. The question of Federation involvement in the domestic affairs of other governments need no be reflected in it. Was something retconned?
