"Although that's another thing, the huge-wars-and-stuff - there haven't been any huge wars since I was named, but if there were, it's actually really ambiguous what I'm authorized to do. Not only on the level of 'will somebody try to kill me if I go encase all their soldiers in ice to make them stop doing whatever they're doing', but on the level of 'is it, in fact, legal within the scope of international law for me to intervene there, or would somebody be technically obligated to arrest me for it, or what'. The test cases for the last few Avatars always wound up getting resolved in ways that didn't set firm precedents."
