I've always read it as at least a little bit a comment on the Iraq war, but what's it's deal? It's the only anime I can think of that climaxes with a military coup, and its cool that mustang wants to put people on trial for war crimes, but then he gets in power and doesn't do it.
It's also just got a whole plotline about racism, but it feels slightly off? Like minorities are okay if they save your life.
I mostly agree, but Mustang didn't get in power. I don't think the show or manga would have actually gone through with showing him or any of the others executed for war crimes, but he's only a general in the epilogue. So you're free to imagine all of the war criminal characters up against the wall if you'd like, it could be canon.
they say he eventually became fuhrer and enacted liberal reforms in Brotherhood, so we can assume be executed some war criminals.
