I don't believe this to be true. The Karma side of this war is, for the most part a loose coalition, most parts of which will probably drift away from each other after the war. I think we will go back to a post-GW1 multipolar era bob, until the next conflict arises. It will most likely be a cycle between unipolarity, bipolarity, and multipolarity from now on.
It truly is a shame IAA was forced to disband. It's good to see NPO is seeing what it's getting for all that it's done. Also hilarious is how so many NPO nations are in peace mode after they forced us out in the GATO-1V war.
