What distinguishes a legal war from an illegal war? Ultimately, the opinion
of the victor. But, there really is more to it than that, in the eyes of
the Law of Nations, and in the eyes of the members of the bodies politic
whose "leaders" are giving the "orders."
How do we determine the "legality" of committing an act of war? To address
this, it helps first to know what is considered to be war, or an act of war.
