> What's the use of a nuclear weapon - a weapon strongest of them all, if the enemy know you will never use it? The only reason to keep nuclear weapons is to keep other from using them. It’s called "mutually assured destruction" — "you nuke me, I nuke you" nobody wants that. I.e. the _reason_ to keep nukes is to never use them. If only one side has nukes, then mutually assured destruction is not possible, and hence there is no safety against nuclear way.
