They'll declare that Fire Nation taxation without proper representation infringes on the inherent and self-evident human rights of all individuals and form their own country, buy a large amount of land from the earth kingdom, steal a grand amount of land from the swamp people to support their ideas of manifest destiny, smite down other colonies in the nearby region under the premise of making said colonial residences independant, and enter world affairs as a smiter of supposed evil and supporter of free rights as hundreds of swamp people inflate the country and supposedly steal the hard earned jobs of the original colonists who have grown fat and happy and now like to throw mud at each other in a facade of intellectual debate and eventually implode under their own mass, taking the world which has become dependant on them down with them and sending the entire place back into the dark ages where the war will begin again, except this time the Fire Nation will burn the entire coastline and sulk that they failed the first time.

Rocks fall, everybody dies. The end.
