<!--EZCODE ITALIC START--><em>From the March/April issue ("Foreign Affairs" is published by the Council on Foreign Relations)</em><!--EZCODE ITALIC END--><br><br>...<br><br>This debate may now seem like ancient history, but it is actually more relevant than ever -- because the age of MAD is nearing an end. Today, for the first time in almost 50 years, the United States stands on the verge of attaining nuclear primacy. <!--EZCODE BOLD START--><strong>It will probably soon be possible for the United States to destroy the long-range nuclear arsenals of Russia or China with a first strike</strong><!--EZCODE BOLD END-->. This dramatic shift in the nuclear balance of power stems from a series of improvements in the United States' nuclear systems, the precipitous decline of Russia's arsenal, and the glacial pace of modernization of China's nuclear forces. Unless Washington's policies change or Moscow and Beijing take steps to increase the size and readiness of their forces, Russia and China -- and the rest of the world -- will live in the shadow of U.S. nuclear primacy for many years to come.<br><br>One's views on the implications of this change will depend on one's theoretical perspective. Hawks, who believe that the United States is a benevolent force in the world, will welcome the new nuclear era because they trust that U.S. dominance in both conventional and nuclear weapons will help deter aggression by other countries. For example, as U.S. nuclear primacy grows, China's leaders may act more cautiously on issues such as Taiwan, realizing that their vulnerable nuclear forces will not deter U.S. intervention -- and that Chinese nuclear threats could invite a U.S. strike on Beijing's arsenal. But doves, who oppose using nuclear threats to coerce other states and fear an emboldened and unconstrained United States, will worry. Nuclear primacy might lure Washington into more aggressive behavior, they argue, especially when combined with U.S. dominance in so many other dimensions of national power. Finally, a third group -- owls, who worry about the possibility of inadvertent conflict -- will fret that U.S. nuclear primacy could prompt other nuclear powers to adopt strategic postures, such as by giving control of nuclear weapons to lower-level commanders, that would make an unauthorized nuclear strike more likely -- thereby creating what strategic theorists call "crisis instability."<br><br>...<br><br>To determine how much the nuclear balance has changed since the Cold War, we ran a computer model of a hypothetical U.S. attack on Russia's nuclear arsenal using the standard unclassified formulas that defense analysts have used for decades. We assigned U.S. nuclear warheads to Russian targets on the basis of two criteria: the most accurate weapons were aimed at the hardest targets, and the fastest-arriving weapons at the Russian forces that can react most quickly. Because Russia is essentially blind to a submarine attack from the Pacific and would have great difficulty detecting the approach of low-flying stealthy nuclear-armed cruise missiles, we targeted each Russian weapon system with at least one submarine-based warhead or cruise missile. An attack organized in this manner would give Russian leaders virtually no warning.<br><br>This simple plan is presumably less effective than Washington's actual strategy, which the U.S. government has spent decades perfecting. The real U.S. war plan may call for first targeting Russia's command and control, sabotaging Russia's radar stations, or taking other preemptive measures -- all of which would make the actual U.S. force far more lethal than our model assumes.<br><br><!--EZCODE BOLD START--><strong>According to our model, such a simplified surprise attack would have a good chance of destroying every Russian bomber base, submarine, and ICBM.</strong><!--EZCODE BOLD END--> This finding is not based on best-case assumptions or an unrealistic scenario in which U.S. missiles perform perfectly and the warheads hit their targets without fail. Rather, we used standard assumptions to estimate the likely inaccuracy and unreliability of U.S. weapons systems. Moreover, our model indicates that all of Russia's strategic nuclear arsenal would still be destroyed even if U.S. weapons were 20 percent less accurate than we assumed, or if U.S. weapons were only 70 percent reliable, or if Russian ICBM silos were 50 percent "harder" (more reinforced, and hence more resistant to attack) than we expected. (Of course, the unclassified estimates we used may understate the capabilities of U.S. forces, making an attack even more likely to succeed.)<br><br><!--EZCODE LINK START--><a href="http://www.foreignaffairs.org/20060301faessay85204/keir-a-lieber-daryl-g-press/the-rise-of-u-s-nuclear-primacy.html">www.foreignaffairs.org</a><!--EZCODE LINK END--> <p></p><i></i>
