As lorgan says, Ibladesh went into the war with the explicit goal of wiping out both Perdan and Caligus. So complaining about how those two realms turned it around and wiped out Ibladesh is rather hypocritical. Especially after Ibladesh had just finished killing Itorunt.
Yeah, it sucks that your realm will probably die. But that's how the ball rolls sometimes. Find a new realm, and start plotting your revenge.
