For more than 60 years, most Americans have thought of nuclear weapons as an all-or-nothing game. The only way to win is not to play at all, we believed, because any use of nukes will lead to Armageddon. That may no longer be the game our opposition is playing. As nuclear weapons proliferate to places that might not share our reluctance to use them in small numbers, however, the US military may face a “second nuclear age” of retail Armageddon for which it is utterly unprepared.

Outside the US, both established and emerging nuclear powers increasingly see nuclear weapons as weapons that can be used in a controlled, limited, and strategically useful fashion, said Barry Watts, an analyst with the Center for Strategic and Budgetary Assessments, arguably the Pentagon’s favorite thinktank. The Cold War “firebreaks” between conventional and nuclear conflict are breaking down, he wrote in a recent report. Russia has not only developed new, relatively low-yield tactical nukes but also routinely wargamed their use to stop both NATO and Chinese conventional forces should they overrun Moscow’s feeble post-Soviet military, Watts said this morning at the headquarters of the Air Force Association. Pakistan is likewise developing tactical nukes to stop India’s much larger military. Iran seeks nuclear weapons not only to offset Israel’s but to deter and, in the last resort, fend off an American attempt to perform “regime change” in Tehran the way we did in Baghdad. The US Air Force and Navy concept of “AirSea Battle” in the Western Pacific could entail strikes on the Chinese mainland that might provoke a nuclear response.

It’s precisely because US conventional power is so overwhelming that the temptation to turn to nuclear weapons to redress the balance is so irresistible.
