You do realise how nuclear war works?
You don't launch nukes at people with nukes or near people with nukes because that's a sure fire way of getting nukes launched at you.
So if you use them at all you only launch nukes at people without nukes and not near people with nukes.
In short the only way a nuclear war can happen now is by accident.
My advice is to tell everyone you have nukes but spend the money on a renewable energy based national public transport system.
