Something Farsun mentioned here in passing is the subject of nukes. We all know there's basically no point introducing them into an RP; virtually every nation on Terra claims to be capable of building them, or at least of having a store of them (with some exceptions, I'm sure).
Obviously, restricting who gets nukes in-game via RP is about as plausible as constructing a functioning global economy for Terra and getting everyone to agree it. But I was thinking that maybe, similar to or as part of OTAF, we might be able to build some consensus on the degree of nuclear capacity of nations?
Of course, in the real world, a nuke is a nuke, and setting one off would be a bad thing, but there are degrees of capacity: the US has a stockpile of over 5000 usable warheads, which are chiefly aerial-launched or missile-based; the UK has a stockpile of c.225 warheads (160 operational) which are designed to be launched from submarines; India likely maintains somewhere around 100 warheads. While the US and India develop their own weapons, the UK bought its current stockpile from the US and hasn't developed its own nukes since the '60s. India's maximum range is thought to be about 5000km; the UK's 12000km, the US is about 15,000km. The US, obviously, can strike more or less at will and has only recently said it won't use its weapons against a non-nuclear nation; the UK claims its weapons are a deterrent, and for use as a last resort; India has a no-first-use policy.
The point I'm driving at is that not all nukes are equal; not only does the capacity of the weapon system differ between countries in terms of range, but so does the purpose of the weapons system and the specific objectives of its construction, how they were acquired, etc. This is probably a good place to start thinking about nukes, IMO. Of course, economics and international relations feed into this kind of thing, too: for example a basket-case dictatorship, might reasonably have bought some (limited, and crap) missiles off another, nuclear-capable nation. But it would be very unlikely to possess the latest weaponry, and so on.
I can't seem to find any information on an RP of who first developed nukes and how they spread around Terra; that might also be something to start working on.
I'm also considering that the development of nuclear weapons requires time: perhaps we should consider an RP convention about how long a nation have been capable of developing/had the intention to develop weapons before it actually has a functioning nuke, how quickly an arsenal degrades and becomes outdated if the country stops work on its arsenal, etc.?
What do you think?
