A respectable and effective protest to the war

[Undertoad]

Speaking from the middle, the question is:

You're walking down a cul-de-sac with your domestic partner and dependents when suddenly you realize that the proliferation of weapons of mass destruction has made the world much less safe, because it has given the ability for a relatively small number of people to do great amounts of damage.

As you walk, your partner says that it used to take a productive government to create such a device - and productive governments are more responsive to diplomacy, as well as to their own people. You remember it is rare for such governments to wage war against each other. In fact you remember that no two democratic governments have ever waged war. But now proliferation has led to unproductive governments getting these weapons, governments that are unresponsive to diplomacy and unchecked by even any notion of decency.

Finally you come to the question. How can the world remain safe and free while nuclear weapons proliferate to dictators who run death camps and drink champagne from gold spigots in marble-tiled halls while their people starve?
