I think we in the A:TLA fandom have missed the absolute potential of the fact that Ozai Firelord is canonically a fucking idiot. I mean the dude's straight up stupid. And I want to be very clear that this isn't a plot hole, this isn't a flaw in the show, this is a fantastic and super realistic element that honestly enhances my enjoyment of it! Dictators are often stupid and breed a culture of cronyism-over-competence. Any similarities with real world leaders, dead or alive, are coincidental yet inevitable.
Well, let's take the Drill. When faced with the problem of Big Wall, Ozai's Fire Nation comes up with Big Drill. One singular Big Drill. Which, as anyone except an idiot could have predicted, immediately breaks down and accomplishes nothing. And if the Fire Nation had made it past the wall, then they would have been fighting through a narrow opening against people who can hurl long distance rocks! Which, if your face or body is vulnerable to high velocity rocks, is a bad thing for you and also for the battle.
Not to mention the resource cost of that thing! It's so insanely gigantic, it must have cost the Fire Nation the equivalent of trillions. For ONE drill. Not ten smaller drills. Just ONE drill. (Fanfic fuel: how much did Ba Sing Se profit off of stripping that drill for parts? Did they reverse engineer it? Did Long Feng keep that for himself?)
And you might be thinking, fairly, that it was War Minister Qin who came up with the drill and you'd be right, but it's Ozai who's approving all this shit. Instead of doing the reasonable thing and asking Qin if he et the whole edible, or even the in-character thing of burning him to death, Ozai just goes... big drill. Makes sense. We should have the biggest drill, because we are the biggest nation. Drill, baby, drill. sorry
It's not the first time, either! He also approves Zhao's invasion of the North Pole, apparently just because Zhao is good at kissing ass and hates Zuko? I couldn't tell you what merits Zhao has. We do not see him lead a single successful mission. The closest he comes is Pohuai, and even then its the Yuyan archers who do most of the work. (My longstanding headcanon is that the reason we don't see the Yuyan archers again is because Zhao blamed the whole thing on them and they were disbanded. This is great fic fuel for displaced Yuyan archers just, wandering around, being elite.)
He approved a massive naval invasion of the North Pole, surrounded by and made of water and ice, inhabited by people who bend water. A nation that was, by its own choice, completely out of the war.
Every time we see Ozai doing something, it's something stupid. Like disfiguring and banishing his firstborn child in a culture that has primogeniture. And then (once he's done pissing away a massive fleet of ships) he does the logical thing and sends his only other heir to bring his first heir back - even though his first heir would have been willing to return with a simple invitation. Like he could have sent a letter saying "dear son come home miss u pick up 200 000 tons of steel qin wants 2 build a drill lol", and Zuko would have come. (Okay, he did have a valid reason for having Zuko escorted, since he thought Iroh was a traitor, but there's absolutely NO reason to risk Azula. Why not send Combustion Man? It's the luckiest stroke of luck ever that Azula is 100 times more competent than her dad.)
Of course, a dictator(-wannabe) sending his daughter on high-level diplomatic missions is pure fiction. Nobody would do that.
The best part of this is that it's entirely realistic and in-character. I could absolutely imagine Ozai purging all of his competent admirals and generals, and then promoting brownnoses like Zhao and crackpots like Qin, because they promised him glorious destinies and secret knowledge of Big Drill.
I also really, really want a scene of Zuko and Azula realizing that their father is a fucking idiot.
I would also like to note that all this stupid shit happens after Iroh leaves with Zuko. So, here's a headcanon: the only reason the Fire Nation didn't immediately implode when Ozai took the throne and purged everyone is because of Iroh. Iroh leaving with Zuko doomed Ozai. It's also a nice little drop of complexity in Iroh's character - he knew he was single-handedly keeping the Fire Nation afloat, yet he only left when Zuko did. Did he plan for Zuko to take the throne from the start? What was his plan before Aang showed up? Did he not intervene in the Agni Kai because he was afraid, or because he knew that Ozai was making a huge mistake and didn't want to interrupt? Give me chessmaster Iroh please.
