It's not real smart to play by the "rules" when you KNOW your opponent will NOT, and will win if you DO.
They could always get a couple of freight companies to hire Blackwater. If I were a freight company and I HAD to send my ships there, I would NOT play by the rules, period. Anyone not identified as legitimate legal authority attempting to board would be killed, every one of them, by my armed crew. And left to float in the area.
My response to the UN or anyone else would be "if you cannot protect my crews and ships, my crews and ships WILL protect themselves".
