Joe talks about nuclear proliferation in the context of mathematical progression below, and expresses his anxiety that we aren’t solving the problem fast enough. I want to suggest something slightly different, and that is the notion of a ‘threshold’. Sadly, it will make him even more anxious – but hey, why should I be here by myself?
I took his post to suggest that the odds of a Nuclear Bad Thing happening increase in parallel with the dispersion of nuclear capability. Actually, it’s worse than that. There’s a threshold – probably a low one – past which it really doesn’t matter much.
I’ll use the example of drinking water.
Water that is 10-6 parts sewage is drinking water. Water that is 10 -5 parts sewage is sewage (note that these are rhetorical rather than exact concentrations, etc.).
It doesn’t matter once the concentration goes up past some threshold level level.
Similarly, as we look at gun ownership in the U.S., one of my arguments with the supporters of strict limitations on gun ownership is that once we have, say, five or six million guns in the U.S., it doesn’t matter how many more we have (we currently have something like 300 million), we won’t see a meaningful change in the violence people commit with guns.
Similarly, once the possession of nuclear technology went past the core five countries, it doesn’t much matter how many more have it, it is going to be essentially impossible to control with the level of absolute certainty that is required.
So we have to find ways to adapt.
First, we have to adapt strategically.
One of the key things that frightens me is that the keystone to preserving a virtually fallout-free 20th Century – Mutually Assured Destruction – doesn’t map well to people who believe that blowing themselves up in a paroxysm of fury and hate is actually a good thing to do.
Next, we have to adapt tactically.
We have to harden our cities, and we have to start now. The good news is that it already looks as though we already have.
And, to some extent, we need to harden our hearts.
Joe and others have posted frequently about the madness that is at the heart of the Islamist movement. It is madness that must be turned and blunted – or must be stopped. I’m not yet at the point of arguing that we must stop it. I believe it can be turned, and that other voices can be found. But we must move to weaken the forces of hate and strengthen the forces that oppose them – all over the world.
That’s a burden, and we have to carry it – alone if needful, although I think that it doesn’t have to be.
Because the alternative will be even worse.
