I disagree with you here, I think the risk is low, not high.
> it's about getting governments to SIGN AN INTERNATIONAL TREATY. It is NOT about having US (or anyone else) policing the rest of the world
We haven't been able to do that for climate change. When we do, then I'll be convinced enough that it would be feasible for AI. Until then, show me this coordination for the damage that's already happening (climate change).

I think the coordination required is much less possible than a scenario where we need to "survive" some sort of danger from the creation of an AGI. But we can find out for sure with climate change as an example. Let's see the global coordination. Have we solved that actual problem, yet?
Remember, everyone has to first agree to this "bomb AI" to avoid war. Otherwise, bombing/war starts. The equivalent for climate change would be bombing carbon producers. I don't see either agreement happening globally.
