Agreed! I think it will have to be a better version of the nuke NPT. Something like every country's government keeps a Mythos like model and that's it. We stop there. Since it's a model; the most powerful country could create as many copies of the model as the countries ready to sign the treaty. But that's it. No more development after that. Somehow countries will have to come together to work this out. What's the solution otherwise? These companies won't stop at any freaking cost.
