Right of conquest?
Kind of shorthand for my own idea of how the world should work. If you attack me and I manage to defeat you and take your land, that land is now mine because you attacked me. You don't even get whining rights to it. Likewise Mexico, Cuba, Japan etc should all belong to the US because they (or the nations that owned them) attacked us and lost. If the world would start enforcing this it would pretty much end war. If you attack and lose, you lose your nation.
