The Atlantic -- which last year ran a convincing piece explaining why we have no military option against Iranian nuclear facilities -- is running a piece arguing that if we can't attack them directly, we must sabotage their machines, assassinate their scientists, and sink the boats carrying supplies meant for their nuclear plants. The model would be covert operations by Israel against the Iraqi nuclear project before Osirak was bombed. This wouldn't solve the problem but would buy us time, perhaps as much as a few years.
I'm all for it, although the question is, of course, if we did buy time, would the Western powers use it sensibly to find a way to derail the project permanently?
I fear not, and that we must begin to plan for a world in which Iran has nukes.
