The ideal state is having the world's superpowers all devoting effort to improving open source libraries, but all catching each others' backdoors and at the end of the day improving security for everyone.
At least 2 rival legal Jurisdictions/Alliances/Spheres
At least 2 rival state intelligence Agencies per Sphere
At least 2 rival corporations per Sphere
TOTAL: 2*(2+2) = 8
Maybe just ignore Hostile, try to find enough competitors to ensure at least one will review, require a couple unaligneds and friendlies, and then consider “too friendly” to be the same as your own country.
Like from a US point of view, if the US and the UK agree on something… I mean, that only counts as one point, right? We are too close. But if like half of the EU and India agree, there’s enough competing self-interest to let it through (keeping in mind that it is all open source, nobody wants to be caught doing something sketchy). And if China, the US, and any other non-5-eyes country agree on something, it must be fine. (I picked these countries because I think they are pretty uncontroversial, I’m definitely not going to try and list who’d be in the hostile group, that’s just asking for unproductive political squabbling).
Multiple possible paths, no veto.
But I have no idea how to fix the problem of: some countries look more or less trustworthy from others’ point of view; I think we can easily suggest a plan from the US point of view, but I have no idea how to get everyone to agree on what the actual state of a single source code repository is, since commits have dependencies. Maybe it needs to be more like a package manager.
