Apparently, it's illegal for nations to send crack assassins into other countries to kill their military leaders. Something like how it's not fair or some stuff like that. Someone who was a lawyer would be able to better tell us why we can't do that.

I would be willing to bet it has something to do with the U.S. President. I say this because the only legal way to kill a head of state right now is to be at war with them first... A condition that few would survive if they tried it against the US
