Frente a la creciente amenaza de una confrontaci\u00f3n con armas nucleares entre las potencias globales, las autoridades de EE.UU. dan nuevo impulso al programa \u201cGolden Dome\u201d (GD). Si bien su nombre se asemeja al reconocido sistema de Def Ae cercana \u201cIron Dome\u201d israel\u00ed, GD consiste en una compleja arquitectura de Def Ae y espacial en capas, que integra sensores satelitales, a\u00e9reos y terrestres, destinada a garantizar la seguridad absoluta de toda la superficie de ese pa\u00eds, frente a cualquier ataque de misiles y plataformas a\u00e9reas con cargas nucleares. El autor del presente art\u00edculo concluye, que toda acci\u00f3n que anule o neutralice las capacidades de ataque con armamento nuclear del oponente, se contrapone con la intenci\u00f3n de lograr la desnuclearizaci\u00f3n de alguno de los pa\u00edses involucrados. Por el contrario, incentivar\u00eda la carrera armament\u00edstica de los programas nucleares.<\/p>\n
US Defense Secretary Pete Hegseth\u00a0will soon report back<\/a>\u00a0to the White House with options for what the second Trump administration has dubbed a \u201cGolden Dome<\/a>\u201d approach to homeland missile defense. The administration seeks an expansive system for defending the United States from missile attacks, which is a stark departure from existing policy. The Pentagon\u2019s review of options is meant to consider the implications of a massive expansion of missile defenses for strategic stability.<\/p>\n But the fundamental vision of a \u201cGolden Dome\u201d may be incompatible with any conception of stability among the major nuclear powers.<\/p>\n President Donald Trump has long spoken of the well-known Israeli Iron Dome system as something of a model for the United States. Trump\u2019s\u00a0executive order<\/a>, which kicked off the Golden Dome review effort in January, states that the United States does not seek to replicate the Iron Dome\u2014a short-range missile defense system best optimized for Israel\u2019s particular security predicament. Instead, the Trump administration seeks to broadly render the continental United States immune to missile attacks from any source by developing a layered, integrated architecture capable of detecting and targeting incoming threats across all flight profiles.<\/p>\n While seeking more and better missile defenses may seem harmless in principle and perhaps even desirable to Americans concerned about homeland security, Trump\u2019s Golden Dome is likely to provide kindling for an arms race that will inevitably clash with his stated desire for \u201cdenuclearization.\u201d The president, ultimately, cannot work toward a world with fewer nuclear weapons while brazenly expanding homeland missile defenses. He will need to choose.<\/p>\n Golden Dome\u2019s rationale.<\/strong>\u00a0The Trump administration states that growing threats posed to the United States by advanced adversary missile capabilities require an ambitious shift in US policy. According to proponents of a more comprehensive homeland missile defense architecture, the ability of Russian, Chinese, and North Korean missiles to circumvent or saturate current US defenses requires a reconceptualization of the missile defense architecture.<\/p>\n After the Cold War, the United States established limited defense against attacks from so-called \u201crogue states,\u201d notably North Korea and Iran; that approach has explicitly excluded seeking a comprehensive defense against Russia and China. Given their large nuclear arsenals, the United States has relied on deterrence to defend against an attack by these adversaries\u2014a posture adopted by both the\u00a0Biden<\/a>\u00a0and the\u00a0first Trump<\/a>\u00a0administrations. No US administration\u2014not even the Reagan administration, famous for its \u201cStar Wars\u201d missile defense dream\u2014ever framed missile defense aspirations in the expansive way suggested by Trump\u2019s Golden Dome order, which seeks to deter and defend against \u201cany foreign aerial attack on the Homeland.\u201d<\/p>\n Strategic implications.<\/strong>\u00a0For decades, the broad aspirations behind US missile defense have remained constant at the margins precisely because of the long-recognized importance of the condition of mutual vulnerability among nuclear peers. In the new multipolar nuclear environment\u2014in which China continues to expand its nuclear arsenal and nuclear saber-rattling from Russia is commonplace\u2014it seems particularly unwise to dramatically jolt the strategic balance with a massive missile defense program.<\/p>\n Nuclear deterrence between countries with roughly comparable capabilities is most stable under two conditions: First, each must possess nuclear arsenals that are survivable enough to maintain an assured ability to inflict unacceptable damage even after a nuclear attack. Second, their adversaries must understand that such a condition prevails\u2014and that attempting to escape this condition of mutual vulnerability will be futile.<\/p>\n The Trump administration\u2019s Golden Dome plans would\u2014intentionally or not\u2014negate these two principles, which generations of US nuclear strategists have broadly acknowledged as conducive to stability. By projecting the vision of a comprehensive homeland missile defense, the administration stirs longstanding fears in Russia and China that the United States does not seek stability but instead seeks to escape vulnerability altogether through expansive investments in missile defense technologies.<\/p>\n While\u00a0Moscow<\/a>\u00a0and\u00a0Beijing<\/a>\u00a0have taken steps to change the composition of their arsenals, the case that the United States\u00a0needs to keep pace<\/a>\u2014either with more nuclear weapons or new missile defenses\u2014should not be uncritically accepted. If the history of the nuclear age tells us anything, it is that adversaries will seek ways of bypassing or counteracting whatever new capabilities the United States deploys. With Russia and China, an arms race will likely include acquisition of more capable missiles that can bypass advanced US missile defenses. An arms race will also almost certainly mean more missiles and more decoys to overwhelm the new US missile defenses. And if all this fails, Russia and China could still deploy new delivery systems, such as underwater autonomous nuclear torpedoes of the kind Russia\u00a0is already building<\/a>.<\/p>\n Seeing a mirage.<\/strong>\u00a0The Golden Dome initiative arrives less than a year before the expiration of New START, the last remaining major bilateral nuclear arms control agreement between Washington and Moscow. Since 2010, this treaty has limited the Russian and US nuclear arsenals, discouraging arms racing. As New START comes to an end, the consequences of jolting strategic stability with an ambitious new missile defense initiative are likely to be extremely serious.<\/p>\n Upon entering office, President Trump quickly expressed an optimistic preference for trilateral nuclear arms reduction and cost-cutting in defense spending. Trump\u2019s inclination for what he has called \u201cdenuclearization\u201d has been reiterated several times since January. He recently\u00a0referred<\/a>\u00a0to nuclear weapons as \u201cbig monsters\u201d and\u00a0asserted<\/a>\u00a0that \u201c[i]t would be great if we could all denuclearize.\u201d Referring to Russia and China,\u00a0Trump said<\/a>, \u201cthere\u2019s no reason for us to be spending almost $1 trillion on military, there\u2019s no reason for you to be spending $400 billion.\u201d Whether these statements will come to arms control or reductions in military spending remains to be seen, but if seen through, Golden Dome will make anything resembling success in this area a mirage.<\/p>\n Trump\u2019s Golden Dome is fundamentally incongruent with the president\u2019s inclination for denuclearization. Not only will massive new missile defense investments\u2014absent a theory of strategic stability accompanying them\u2014largely eclipse\u00a0cost reduction initiatives<\/a>\u00a0elsewhere, but the arms race it risks setting off further clashes with Trump\u2019s desire for a world free of nuclear weapons.<\/p>\n A comprehensive homeland missile defense would risk upsetting strategic nuclear stability. It would also encourage arms racing and mark the onset of a vicious, self-reinforcing action-reaction cycle. To mitigate the worst possible consequences of a new arms race between the United States, Russia, and now China, US lawmakers should be ready to question and exercise oversight over the new administration\u2019s missile defense aspirations as they crystallize in the following weeks and months. Failure to keep the Trump administration\u2019s missile defense plans in check risks taking the United States down an expensive road that goes nowhere but increases the risk of nuclear war.<\/p>\n
