The Stimson Center has a fun scenario, Cheater’s Risk, in which you can attempt to evade international detection in pursuit of bomb.

The odds are stacked against you (well, so they are in real life!)

I did pretty well, I must admit.

I had the UAE pursue aerodynamic enrichment, recovered the uranium from sea-water and then rendered it into a small arsenal of 1-5 nuclear weapons. (In retrospect, I had a 46 percent chance of success.) I decided to skip testing.

Imagine my pleasant surprise to receive a lecture from Ward Wilson encouraging me to abandon my illicit weapons.

From my cold dead hands, Mr. Wilson!

Seriously, who hired Ward as National Security Advisor? Was Brent Scowcroft busy this weekend?

I also managed to pilot Madagascar up through a heavy water reactor, reprocessing and weapons assembly until I decided to test the device. There was no “flash in the South Atlantic” option, but you bet those jackasses in Mozambique were surprised!

For the record, we are still claiming it was a clandestine American weapons test run out of Diego Garcia. I mean, Madagascar? And no, Mr. Blix, you cannot inspect that large box nestled in the hillside. It is my private lemur breeding facility.

One might have small differences of opinion about risk here and there, or moan that the scenarios aren’t detailed enough. For example, it looks like you have a set 98 percent chance of having your nuclear test detected, regardless of location.

But those are minor things.

I have only one serious objection, which is illustrated by my two country choices: The scenario permits no ambiguity on the issue of detection. Yet, the UAE is well positioned to acquire nuclear weapons components precisely because it is such a major transshipment point. If you discover a controlled component en route to Dubai, you can’t really be sure its ultimate destination isn’t somewhere else. Similarly, having successfully evaded detection of my heavy water reactor and reprocessing plant, how does one attribute that the surprising flash of light and resulting plutonium particles to me instead of, say, Israel? I picked a pair of countries that minimized detection by shrouding the most obvious indicators with ambiguity.

You can see an example of this with Burma right now: Has Burma been “detected”? Maybe. But there are a lot of people who think the jury is still out. I don’t have any brilliant idea about Cheater’s Risk might have handled this, but it is something to think about.

Which is, it turns out, the great value of this simulation — as a heuristic device. I am glad Barry and Alex created it.
