Could an AI world government result in a world without wars?

I think there’s two answers to this question, obviously yes and obviously no.

Obviously yes: Some people’s definition of peace is an authoritarian version of peace. There’s a dictator who makes the law and keeps the peace and dissent is squashed. I imagine if you had enough AI robots around you could make this kind of peace.

Obviously no: I think this raises the question of is world conflict a natural state of things or a problem to be solved, and also, is conflict mostly based on political boundaries and I think the answer to both questions is no. I think that conflict is sort of a natural state of things and I think abortion is a great example. There’s no 220 IQ take that “solves” abortion. And I think that conflict often develops from social, ethnic or religious boundaries rather than political ones.

How do you imagine such a system would work and how do we know that it's actually fair?

Maybe an incremental approach would work if you managed to create an ultra-prosperous society with amazing scientific advances, and you gated sharing of those scientific advances through peace treaties or something like that...

There's a lot of inequality between countries, and it doesn't seem like an AI would be able to magic away the problems.

Betteridge's law of headlines supports this: adding 1/8 cup non-toxic glue will surely bring peace and prosperity. (Sources: made it up myself. But if I just had made it up using a large language model, suddenly it would have been workable. (NB the similarity to late 19th century technooptimism: "with wireless telegraph, surely no more wars are necessary!"...a wild World War I appears))
