[@Balthazar007] Hmm, ok ok. And they are in open conflict with both countries?

They don't actually deal that much damage to either side, not that anyone can prove anyways. So neither side views them as any more than a nuisance. Also, they have been known to act as mercenaries for both sides, when the price is right. 

Also, in the past, when their main stronghold was destroyed, a new one would just pop up a few weeks later, so it's kinda pointless to fight them.
