Very much for nuclear proliferation wonks—sporting historical data, employing a methodology, and testing a hypothesis—”Leveraging Latency: How the Weak Compel the Strong with Nuclear Technology” may also appeal to post-WWII-history buffs, simply because it is so appealingly executed. The author, a historian at an American naval school, exhibits full control of his narrative and writes in a perky, clear style that makes for sweet reading. His argument, that potential nuclear proliferators can sometimes strike advantageous bargains with large national powers but only at a certain “Goldilocks” sweet point, is most persuasive. At a time when an academic or semi-academic treatise on nuclear proliferation seems to be born every six months, Leveraging Latency shines out.
