Give them arms that would have been given to cartels and let them gather their people, that army which they have made, and force them to go to their own fucking countries and kill the fucking retards that are crapping up their land and this planet so that there is no longer any need for this predicament. Didn't they call themselves an international army of some sorts? They're practically mercenaries in the making already, just have them fight for their homelands and overthrow their corrupt puppets. If arming them is not possible, kill them all.
