One aspect of this episode didn't ring true to me. Duras' forces attack Gowron, and Picard's response is to withdraw. Kurn comes to the rescue, and the Duras forces withdraw as well. Gowron's then says to signal to the Enterprise to return to witness the installation ceremony.
He sure got over them bailing pretty quickly. Wouldn't he have been enraged that the Federation turned its back on the "true" leader of the Klingon empire? He seemed way too cordial about that.
Well, in the end, the Federation did provide some measure of aid in the civil-war and he was planning on "re-writing history" to remove any Federation involvement anyway, further, well, Picard *was* responsible for him being even there to be installed anyway, so I guess he got over it.
And while he hadn't been installed, officially, as the Chancellor just yet he was for all intents and purposes the rightful leader of the Klingon Empire. I'd say equivalent to a "President Elect." If a person had been rightfully selected as the next President but the rules and laws of our nation and his opponent started a civil war because he thought *he* should be installed as President our allies, or any support, should rightfully go behind the man who was legally selected as President.
The Duras tried to start the rebellion and civil war on the notion that the Federation had more to do with the choice than any Klingon rites or traditions but we all know that was their "talking point" and gambit, so to speak. The Duras just wanted the power and, more over, facilitate a union between the Klingons and the Romulans. They couldn't care less about the Federation being involved in the selection, Duras himself didn't seem to care. He had some squabbles about the methodology Picard went with but seemed to accept the rites of succession Picard went with.
Though, I think (Kempec?) was a bit foolish and short-sighted in selecting Picard as the arbiter. He really should have known the problems it would stir-up considering Picard was an outsider and not only that a member of a government/organization the Klingons had only relatively recently had peaceful relations with. Picard mostly from an era when there were struggles between the Klingons and Federation.
It *may* have made more sense for Kempec if he really didn't trust any councilman or other Klingon to give Worf his honor back and select HIM as the arbiter but even that would have caused its own problems. Given Worf's recent dis-commendation and the presumed connections his family had with the Romulans.
Also, the Duras didn't seem to be *too* secretive about the Romulan connections, particularly when the civil-war started. Certainly those who stood with them would want to know where supplies and aid were coming from and would notice the activity along the Romulan border and the occasional Romulan ship in the area. Give the history between the Klingons and Romulans you'd think, despite their feelings on Gowron and how he got to where he was, the Klingons supporting Duras wouldn't like the Romulan connections.
