You realise that these people are running for their lives, right? Every day they die on the way. What would you do? If they stay, they will have to support one of the sides. And when it comes to it, you blame those people for staying and fighting for either side. They can't win, can they? Because they do not count as humans after all.
Fuck the area as much as you can, then go "oh end is nigh! we are over run!"
Too bad they cannot run away to live in the US.
