While I love and appreciate the patriotism, Xavax was never going to steamroll Alara. Itorunt alone has half as many people as all of Xavax (Current poplutarion is 50k vs 91k). in fact, Alara actually had MORE citizens before Xavax took 3/5 of their regions. When you only have to split that gold 6 or 7 ways, that is a whole lot of money, and Minas Nova has enough rurals to feed them forever.
Propaganda-wise we make out Perleone to be some big financial backer, but we've no way to verify and Alara may not actually have NEEDED financial backing.
This was never supposed to be easy, but at least it hasn't been dull!
