There's evidence he was trying to prevent worse things from happening. He hid the last dragons, he joined a extremist group, he was WAY ahead of Azula capturing him, his prison escape plan was likely a long term thought process he already had. Iroh was never going to be fire lord.
I want them to dive into exactly that in NATLA, more than they already have.
Maybe it's just me, but I'm really enjoying it as an 'AU' that explores some off-screen scenes and implications from the original. I think people are getting too hung up on it being 'not ATLA' (just like LoK).
There's no central authority, but it's not a machiavellian free-for-all like medeival Europe. The rest of the world was rather unhappy with the Fire Nation's aggression, even in light if the world's long history of warfare. He would be tried for that, no doubt.
And his reputation/nickname is subtext for crimes he did commit but that the cartoon couldn't spell out.
No, it's not a war crime that I can find, however we can attribute harm caused to civilians through these actions, such as starvation due to supply lines cut off. So he did some vile shit, had a moment where he realized the error in his ways, then did everything in his power to make things better.
Except there no evidence of starvation in Ba Sing Se. After all, there was so little impact that the citizens could be convinced that there was no war.
As to supply lines, earth benders cannot be locked in by a siege. They can create tunnel networks with a literal wave of the hand.
I mean really the existence of war crimes relies on the existence of treaties between the nations defining what those crimes are. Gonna guess the Fire Nation was not a signatory.
The Nazis weren't signatories to the Nuremberg charter, yet they were judged by it. So there is precedent for judging war crimes without pre-existing law.
Depends on the culture The Japanese viewed siege tactics as cowardly and armies at the gates would deliver food and supplies to the people in the walls. Ba Sing Se was able to convince it's citizens there wasn't even a war going on, I don't think they were starving or being killed with siege weapons.
The source you provided makes clear that sieges are lawful provided non-combatants aren't affected (so starving civilians, barring humanitarian aid, etc. makes a siege unlawful). Furthermore, it states that sieges where non-combatants are affected were lawful prior to the 20th century.
In the context of ATLA, there's not really enough known about the geopolitics of the world to properly gauge whether or not besieging a city is a war crime. The frequency of sieges in the show (North Pole, Ba Sing Se) can't be used as an argument for their legality since they're undertaken by a state that is known for mistreating prisoners of war, disrespecting geopolitical boundaries, and so on. Regardless, you can't judge the Avatar universe by real world law.
If Varrick were real, he would have blown himself up because he had a hissy fit, threw his briefcase at the wall, but forgot there was a bomb in there.
A war crime according to... Who? Is there some treaty or convention that happened? Is there some customary international law that he violated? I can't find the Hague anywhere on any maps in this universe but maybe I missed something.
They should have gone back and edited the show rather than do this. The Iroh and June thing was way out of character for Iroh to begin with. Likely some writer that was unfamiliar with the show and took too much inspiration from Master Roshi.
