What you should be doing is getting over yourself and accepting the situation. I think it's highly unlikely that Fronen will be completely destroyed... but they will have to shrink severely.
What he should be doing is figuring out why they did not correctly predict what happened, understand why that happened, fix the situation so that it doesn't happen again, and then figure out a way to turn things over so they can win the war. Nothing is inevitable in BM.
Saying "you have to accept the situation, Fronen will need to shrink" does sound like OOC influencing IC behavior. I'm not saying your character did anything wrong, mind you; I personally think this war happened for perfectly legitimate reasons, and I'm glad I had a character come back to Riombara just in time to beat Enweil again.
There is no conspiracy here. One side seems to be winning through a combination of good diplomacy and good timing. That happens, and that can change.
