Due to the nature of my work, design to give products competitive advantages using cognitive science concepts, most of my work is under Nda agreements. Sometimes I can share who I have worked with and some generalities of the solution but that's it.
Some months ago I created a submission for G4C ( games for change) and n squared for their nuclear challenge. My proposal wasn't selected (an Oregon trail clone did) so I decided to make my submission public. Its side project quality but it I feel it's a good example of how to approach a big topic as nuclear disarmament focusing on behavior.
I know you don't plan to read the pdf so here is a short summary of the idea.
The main problem of nuclear weapons right now is not that some government will start nuclear apocalypse. We survived the cold war and the public feels that full nuclear warfare is a thing of the past. Although in reality there is a fair chance of this happening, we survived the cold war, when nuclear war was almost a certainty. So this scenario won't sway public opinion towards disarmament.
The problem with nuclear weapons is that they are old, each year their programs receive less resources and the personnel responsible for them is, as every human, prone to errors. You can watch John Oliver note here
All of this factors are terrifying especially considering that the accidental launch of one warhead will probably lead into a full blown nuclear war. One detonation will cause the response mechanisms set in the cold war to activate.
I designed a game that puts you in charge of the maintenance of a nuclear silo. The catch? You cannot quit, so when the game gets boring you will eventually skip your maintenance duties and cause a launch. By making the public experience how hard is to keep maintaining this weapons, they will be able to take the conclusion that there is no safe nuclear weapons.

An omnipotent solution for solving intended launches was proposed by a Harvard Law professor, Roger Fisher, writing in 1981.
