Sci, you're interested in the (putative) mechanisms of Federation government--do you figure ambassadors have to be confirmed by the Fed Council, like our Senate does, or can the President just appoint willy-nilly? I'd suspect the Federation has at least as many checks and balances as the U.S. government, if not more.
Hmm. An interesting question. The novel
A Time for War, A Time for Peace had a subplot wherein it was mentioned that when a new President takes office, all currently-serving Federation ambassadors tender their resignations so as to give the President the choice of retaining them or finding new ambassadors as the President sees fit. I don't remember a reference to the Council needing to ratify an ambassador or not.
My inclination would be to conjecture that the Council ratifies ambassadorial appointments to foreign states but not Ambassador-at-Large appointments, but that's just my guess.
I do know that the novels depict ambassadors as being members of the Federation Diplomatic Corps (which was mentioned in
Star Trek: Insurrection), which seems to be a division of the Federation Department of the Exterior (the Federation's equivalent to the U.S. State Dept. or a foreign ministry).
Though, I'd be amazed if the Grazerite would even consider Worf.
Actually, the DS9 episode "Extreme Measures" refers to Jaresh-Inyo as being a former President by the time of DS9 Season Seven (2375). The novel
A Time to Kill by David Mack and the eBook
Enterprises of Great Pitch and Motion by Keith R.A. DeCandido establish that DS9 Season Four, 2372, was an election year, and that shortly after "Homefront"/"Paradise Lost," Jaresh-Inyo lost the election to then-Federation Councillor Min Zife, a Bolian who ran on a platform of increased militancy in anticipation of the Dominion War. Zife assumed office in early 2373 (DS9 Season Five) and resigned in 2379, just before
Star Trek: Nemesis (as per the novels
A Time to Heal by Mack and
A Time for War, A Time for Peace by DeCandido), succeeded after a special election by Governor Nanietta Bacco of Cestus III.
Besides the extreme, EXTREME conflict of interest he would have regarding his duties to the Federation and to his new House,
Well, the first thing I would point out is that Worf has never sided with the Klingon Empire over the Federation, nor, with the exception of one incident (saving Jadzia, his wife, over a Cardassian defector), has he ever done anything to undermine the Federation. Probably the ultimate test of his loyalty to the Federation came in 2372 ("The Way of the Warrior" [DS9]), where Worf sided with the Federation over the Klingon Empire after the Empire sought to invade the Cardassian Union to overthrow the Detapa Council.
It's a potential conflict of interest, but it's also a potential source of leverage for the Federation for a couple of reasons. One, his relationship with Martok means that the Chancellor is more likely to listen to him and to trust him than he would any other Federate. This increases Worf's ability to influence Martok. Two, it also makes Martok inherently more likely to feel, and/or to enact policies, favorable to the Federation, helping to solidify an alliance that both sides need in the wake of the war. Three, Martok literally owes his job to Worf; that means that Worf has some bargaining power over him. Four, Worf has a better understanding of Klingon culture than damn near anyone else in the Federation.
he has little actual diplomatic experience,
He has little
formal diplomatic experience in terms of holding a political office, but in terms of solid experience, he's one of the most influential political actors in Klingon politics. He entered politics as far back as 2365 (TNG S2), when he allowed himself to be discommendated by the Klingon High Council to preserve Klingon unity. From there, he participated in the post-K'mpec succession crisis, supporting Gowron over House Duras and helping to save the Empire (and therefore the Federation) from having a Romulan puppet government on Qo'noS. His actions led to the installation of the Klingon Emperor, Kahless II, and to the exposure of the Changeling impersonating Martok. He then saved Martok and restored him to the Defense Force, led Klingon forces numerous times during the war, and overthrew Gowron and installed Martok. In other words, Worf has been either personally or partially responsible for the last two Chancellors' ascensions to power and for the installation of the Emperor himself.
The guy's got some experience, 'kay?
unless killing the head of government of an allied nation while serving as a representative of your country's military counts as diplomacy. Of course, viz. the Klingon Empire, maybe it does.
Of course it does. These
are Klingons we're talking about.
More like the Federation Council never confirmed him as an ambassador to Kronos because he's Martok's freakin' relative. Can you imagine our amabassdor to China being Hu Jintao's adopted son?
Actually, that would probably be more akin to the U.S. Ambassador to the United Kingdom being Gordon Brown's adopted brother. (And, yes, the relationship between Martok and Worf is more brother-brother than father-son.) The Klingon Empire is the Federation's partner and ally, and apparently its closest such; it's a much less adversarial relationship than that which exists between the U.S. and People's Republic of China.
Hell, take it a step further - in addition to being Martok's adopted kid, he's also (albeit rather nominally) the ex-Klingon Chancellor in his own right. And hand-picked Martok as his replacement (or Gowron's replacement, if you want to overlook Worf's two minutes of Chancellorship).
I can't conceive of a way that it would seem like a good idea for the Feds. For Martok, certainly, but not for them.
Actually, one could very easily turn it around and spin it another way:
From a Klingon nationalist's POV, the whole thing makes
Martok look much more like he's
Worf's -- and by extension, the Federation's -- puppet than the other way around. I mean, seriously. Gowron gets his job because Worf and Starfleet ally against the House of Duras during the Klingon Civil War. Then Worf puts the Emperor into office. Then Worf sides with the Federation when the Klingons decide to save the Alpha Quadrant by overthrowing what they believe to be a Dominion puppet government on Cardassia -- and then, after the Federation finally starts fighting the Cardassians/Dominion, the minute Worf and Starfleet get unhappy with Gowron's policies, they overthrow him and install Martok.
Really, in a lot of ways, Martok has much more to lose from Worf being Federation Ambassador to the Klingon Empire than the other way around. It's going to make a lot of folks in the First City wonder if Martok isn't in essence a Federation puppet chancellor rather than his own man.
Bottom line: The Federation government obviously believes that Worf is trustworthy enough that they feel he will not compromise his loyalty to the Federation if it comes down to a choice between Martok and the Federation. And they recognize the advantages that Worf's appointment will give them. Frankly, I think they're right.
