I don't think the war has been stopped. If Karbinskia and the Zuma could fight together during the same battle against Terran then I would say it has. But since the Zuma just fought the Kabrinskia army that doesn't seem to be the case. I think Terran and Barca can take on FangFang.
Do it! Doooo iiiiit! Some of us are desperate to live vicariously through the southwest's (mis)adventures.
