>Achilleus' and Agamemnon's "struggle" is not the focus.
Go look up what is literally the fucking first line of the poem. Any translation you care to use.
>The effects, yes -- for example, the Atreides figuring out just how the fuck they're going to survive without Achilleus. As for their "struggle" -- it soon turns into Achilleus' own struggle with himself, and his destiny, and glory.
And why he should be listening to someone like Agammemnon, and eventaully coming to full circle and realizing he should, even though he's the better warrior and better war leader. Did you miss the javelin toss episode of the funeral games?
>And then the whole thing ends when it becomes apparent to Achilleus that it was meaningless in the face of his friendship with Patroklos, which now is finished.
No, it ends with him swallowing his pride and letting Priam have the body back, because he realizes that it's actually not all about him, and he should step up and take some damn social responsibility.
>. Read the last stand-off between Achilleus and Hektor, and tell me Hektor's speech isn't the culmination of much of the novel.
It isn't, because Achilles doesn't actually listen to a damn thing he says. It's only afterwards, when he realizes that glory is in the minds of others, not his own, and that he needs to play the social game, instead of doing whatever the hell he wants, that it penetrates. It's not a culmination, it's a tightening of tension, a chance for Achilles to learn, and his failure to do so, foreshadowing the events in the next book.
>The fact they both must struggle at all is what I'm talking about.
And again, the struggle between the two doesn't actually resolve anything; it doesn't end the war one way or the other, and it doesn't actually resolve Achilles's internal conflicts. It is thematically undercut as early as book 7, when Ajax ekes out a narrow win against the guy, albeit a non-fatal one, and all the Achaeans are crowing that Troy is finished.
