DISARM AND MODERNIZE

In the early decades of the Cold War, NATO made arrangements to bury what were known as atomic demolition munitions (in essence, nuclear mines) at key points in West Germany, to be detonated if Warsaw Pact forces ever invaded. Although this plan, if enacted, might have slowed the enemy advance, it also almost certainly would have turned vast West German territories into radioactive wastelands littered with corpses and smoldering buildings—the stuff of hellish alternative-
history scenarios. The West viewed such tactical nukes—NATO fielded 7,000 to 8,000 of these shorter-
range, smaller-yield weapons for most of the Cold War—as tripwires in anticipation of the Soviet Union’s own Strangelovian plans for its thousands of tactical weapons. That is to say, the forward positioning of these nukes was a signal: If the Soviet Union invaded Europe, confrontation would escalate quickly to the nuclear realm, and the United States would intervene.

China, for one, has long professed a goal of minimum nuclear deterrence—that is, an arsenal that is just large enough to inflict unacceptable damage on any country that attacked China first—and is estimated to have about 250 warheads for delivery by land-based missiles, bombers, and an emerging submarine fleet. But China is also engaged in continuing, low-level disputes with its neighbors—the Philippines, Vietnam, and other countries—over control of the Spratly and Paracel island groups in the South China Sea, where Beijing reportedly has been building man-made islands from reefs and shoals to host military facilities. In the latter stages of an aggressive, two-decade program of upgrading its land-, sea-, and air-based nuclear delivery systems, China is the only member of the five NPT-declared nuclear weapons states increasing its arsenal, albeit slowly.


In South Asia, meanwhile, what may be the world’s most threatening nuclear face-off—exacerbated by long-simmering distrust and military competition between Pakistan and India, a continuing border dispute over the Kashmir region, and allegations of Pakistani support for terrorist attacks in India—seems to be spawning a modernization race. Both India and Pakistan are upgrading their weapons complexes to produce increased amounts of bomb-grade uranium and plutonium, which would provide the countries with the ability to build more warheads.

Pakistan’s expansion is notably rapid. Today, the country has an estimated 120 weapons, an increase from around 90 in 2007. At its current pace, Pakistan could have 200 nukes in its arsenal within a decade. Beefing up its tactical weapons, the country is developing a new medium-
range ballistic missile, new air- and ground-launched cruise missiles, and a short-range nuclear missile, the Nasr (officially known as Hatf IX, meaning “vengeance”—a theatrical choice that reflects the nuclear politics of the region). The Pakistani military claims that the Nasr, a mobile system with a range of 60 kilometers (37 miles), is highly accurate and able to carry nuclear warheads. It is designed for “shoot-and-scoot” warfare—that is, firing at a target and then immediately moving to avoid enemy counterfire—and apparently is meant for use in the event of an invasion by India’s conventional forces, widely seen as superior to Pakistan’s.

An analysis of the potential use of tactical nukes in South Asia—relying on the outlines of the 1965 India-Pakistan war as a guide to invasion routes—suggests that Pakistan’s detonation of just one
 30-kiloton battlefield weapon would not only affect invading Indian forces, but also cause the loss of at least tens of thousands and probably hundreds of thousands of Pakistani civilian lives, according to Jaganath Sankaran, an associate at the Managing the Atom project at Harvard University’s Belfer Center for Science and International Affairs. In turn, India is developing longer-range ballistic missiles, including the Agni-V—agni is the Sanskrit word for “fire”—with a range of 5,000 kilometers (3,107 miles), making it capable of reaching any target in China, its primary regional rival. In addition, India has launched its first ballistic missile submarine, the Arihant, meaning “slayer of enemies” in Sanskrit, which is expected to be followed by several others that will eventually have the capability to launch ballistic missiles. This is significant: Pakistan has long warned that it would consider an Indian submarine armed with nuclear missiles to be destabilizing.
