Maybe the wording is bad: 'anti-war' brings to mind college students ranting about how we should all live together happily. The Greeks had a little bit more realistic view... and they certainly appreciated irony. The Iliad is more of a 'what hath our honor wrought?' look at war. You have Hektor and Achilles portrayed as the two absolutely most noble individuals forced to fight and die on opposing sides because they're bound to defend the honor of men who are painted as ignoble and dishonorable. It's not a blatant "we must stop war!" rant type of thing (although it does dabble in that -- the horrific violence and such... what sticks in my mind right now is Hektor's son not recognizing him because he's wearing his war helmet) -- but it's definately a very ironic portrayal... these are the best of men and they must suffer because of their nature. Certainly the story of the Trojan war was originally 'war is great, we went and fought, yay'... but Homer gives it a decidedly 'look at this and see that it's wrong' bent.
