What are the responsibilities of a country that is occupying another?
The first question can be answered by determining whether or not the occupation was justified or not. A key determining factor is that conflict may be justified if all peaceful options have been exhausted. If the conflict was justified, then your responsibility would be to carry out your mission in a precise and mindful way. If the conflict is unjustified however, things become a bit more complex. The degree by which transgressions against the non-aggressors occur dictate the responsibility the aggressor should then take. The principle is quite simple: if I wrong someone, I need to do something to make it right.
