What?? What's that supposed to mean? Implied? All I saw was the destruction of a major threat to the alliance's continued existence, the death of the empire's two principle commanders, and the redemption of Anakin Skywalker. How exactly is that supposed to result in the wholesale defusing of conflict? You've got an allegedly galaxy-wide political/military entity bent on conquest and despotism. Are you seriously suggesting that the deaths of the Emperor and Vader and the destruction of the Death Star would result in the pacifying of every other Imperial V.I.P.? They're all just going to lay down their arms and sing "kumbaya, my lord" and allow the Alliance to fill the power vacum uncontested? That's just asinine.
Quoting an obviously poetic closing line from the novelization does nothing to make the notion any more plausible. And saying that ROTJ's ending implied the end of the conflict is just absurd. Are you suggesting that the rebels wouldn't have a victory party after a major watershed success in the campaign against the Empire unless and until the conflict was 100% resolved and over?
