Moments later, hedging a bit, Dagan admitted that it was "not exactly our rational." He then proceeded to hedge even further, indicating that Mahmoud Ahmadinejad was "not exactly rational based on Western thinking."What, exactly, was Meir Dagan saying? Reduced to its bare essentials, his statement claimed only that Iran's leadership displays some form of "logical thinking." Nothing more.To be sure, there was literally nothing in his remarks to suggest that the regime in Tehran would consistently value collective survival as its highest goal.Such an omission was plainly significant. This is because the rationale of strategic deterrence must always rest upon a uniformly presumed preeminence of national self-preservation. By definition, where such a presumption is absent, there can be no traditional deterrence.
