I have to agree with Dread, you are very aggressive Grim, coupled with a mighty confidence and bragging about humiliating other nations, one can't help but basically team up with everyone who's keen and dog pile you.
Don't even complain about it, the way you were acting before was basically asking to be ganged up on, what I'm concerned about is TNN deciding to attack the coalition, but you aren't even trying to get them on your side despite them already de-facto helping you anyway, if you were a character from baldurs gate, you'd have heaps of stats and Charisma -3 or something, even the squirrels would attack you.
Your knowledge of the game is greater than mine by a long shot, perhaps greater than anyone else in this game, but perhaps your diplomacy skills are about as sharp as a tree trunk.
Oceania you should help us attack Grimwulf, because if you ever wanted revenge this is your best chance, maybe you won't kill his giants, maybe you will suffer, maybe you will die, but you will die with honor, fighting with the free nations of this world against the tyranny of the ice giants.
with our combined powers
We are already martyrs, this is our time.
