A few things from the official Freedom novel by Liu Goto. We'll suppose it is canon and follows the movie faithfully.
NOTES:
Spoiler:
- At one of the first public screenings, Fukuda is said to have expressed interest in a
prequel to Freedom, centered on this unseen Gundamjack.
Take this with a huge grain of salt, 4chan comments are by no means Word of God.
- Agnes is more of a Fllay-like gold-digger/social climber than first described and has quite the spiteful tongue, too.
- The whole "Foundation breaking away from Eurasia" and "Orphee Lam Tao being acknowledged by Durandal" raises questions on the whole timeline, especially it makes one wonder how did Coordinators successfully orchestrate a coup d'état in a region that is nowadays quite the Blue Cosmos hotbed. Also makes you wonder whether Aura and Gilbert were in true cahoots (Foundation's breaking off being possibly one of his peripheral schemes to weaken the EA) or if they simply had relatively similar dreams they were pursuing independently of one another.
Personally - I don't really like this Accord thing, which feels tacked-on as a means to align the whole Coordinator concept (which was its own thing and I hoped it'd stay that way!) closer to the Newtype/Innovator concept from other Gundam universes (and Fukuda
does borrow a lot of things from other Gundam franchises in the movie, be it the Z'Gok, the Gyan, the G-Bit, the Gundam 00 Raiser - just to cite the more obvious ones). Especially with Kira being dubbed a "failed Accord", as it rewrites the whole Ulen Hibiki backstory and draws up unneeded (IMHO) entanglements. Hibiki's Ultimate Coordinator project was started to solve one problem, which was the sharp fertility drop-off issue after three generations and the rising number of stillbirths. Hibiki partially solved it with the artificial womb and then designed, with his son as the medium, the ideal Coordinator whose genes made the stillbirth problem a non-issue (though it is unknown what causes it; it's clearly said in SEED that the biggest wildcard in Coordinator pregnancy was the mother's womb, but it is not clarified, AFAIK, whether the womb was rejecting the embryo as if it were a foreign body contaminant or if the embryo was simply failing to survive in the uterus)...it wasn't a "I will create the perfect supersoldier" plan at all, nor was it a "I will create the next world leader" plan, either - at least that we know of (and Raww did not allude to this, either, in his fevered ramblings). Ulen's dalliances with Al Da Flaga were an acceptable plot twist (why? Because it explains how Kira could have inherited his Newtype abilities from the Da Flaga gene pool, which Ulen had access to), but this new Accord thing makes it feel like a tangled web. Hibiki's single-minded pursuit of perfection and the ideological can of worms that is the Destiny Plan are not...fundamentally...incompatible, but it does make me wonder if, as a Natural, he'd have agreed with it given that the implementation of such a sweeping social program would have stuck him somewhere in the middle of the human pyramid of genetically-determined merit; he strikes me as too proud an individual for that (and he already had reservations on the subject of cloning, but probably needed the money anyway).
Of course, the extradiegetic explanation to the introduction of the Accord stuff is that the scriptwriters needed something to prop Lacus up and rationalize her presence inside Strike Freedom (aside from presenting a mirror image to Cal-re.A's Orphee and Ingrid pilot crew) aside from giving Kira a pep talk...
...and provide a good reason why COMPASS gets such a thorough trashing midway through the movie.
