A to a greater extent than competitive international environment, in addition to inwards detail Russia’s assertive policies, has sparked renewed involvement inwards the concept of nuclear deterrence inwards Western defence strategies. For NATO, this rediscovery has manifested itself (among other things) inwards a thorough analysis of Russia’s nuclear policy in addition to posture, renewed attending to NATO’s ain nuclear arrangements, in addition to a stronger emphasis on nuclear deterrence in addition to nuclear arms command inwards populace statements. But there’s more. Major changes inwards the global nuclear landscape, including inwards nuclear governance, may before long position renewed pressure level on this of import role of NATO’s deterrence strategy. Allies ask to await non exclusively at the challenges posed past times Russia’s nuclear modernization, but also ponder the implications of other—potentially much to a greater extent than far-reaching—changes. Three areas stand upward out.
First: nuclear use. In the autumn of 2017, North Korea’s unusual government minister warned that his province could detonate a nuclear device over the Pacific. Such an incident—even if it were exclusively intended for political “signaling” purposes in addition to would non drive major casualties—would endure a game changer of tremendous significance, deepening the rifts that characterize the electrical flow nuclear debate. For some, it would reinforce the conviction that nuclear deterrence remains essential for prevailing inwards a nuclear world. Others would run into nuclear exercise equally a sign that nuclear weapons accept failed equally a agency of inducing restraint inwards international relations. In short, the opened upward societies of Western nuclear-weapon states in addition to their allies could endure heading for an acrimonious debate.
Second: a major non-nuclear assault against the nuclear military machine infrastructure of a nuclear-weapon state. Influenza A virus subtype H5N1 cyberattack, for example, that would atomic number 82 to a temporary loss of command over nuclear weapons could foster the perception amid the broader populace that nuclear weapons are no longer a safety provider but a safety liability. Although the 2018 U.S. Nuclear Posture Review does non explicitly refer to cyberattacks, its emphasis on the ask to deter “significant non-nuclear strategic attacks” on, inter alia, nuclear forces in addition to their command in addition to command capabilities, indicates an awareness of this emerging challenge.
Third: a major alter inwards the legal framework for nuclear governance. Influenza A virus subtype H5N1 Treaty on the Prohibition of Nuclear Weapons, which seeks to stigmatize nuclear weapons equally illegal, is similar a shot good nether way. But because nuclear-weapon states (and their allies) cannot endure leap past times a treaty that they persistently object to, it volition non atomic number 82 to global nuclear abolition. However, it could deepen the rift betwixt nuclear in addition to closed to non-nuclear-weapon states, equally good equally complicate NATO’s relations alongside closed to partner countries. Moreover, designating nuclear weapons equally illegal could also push clit the carpet from nether the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which remains the exclusively near-universal framework for the rule of nuclear possession in addition to non-possession.
These game changers would non exclusively deport upon NATO’s safety environment, but could also challenge its political cohesion. Three pointers could tending frame the futurity intra-alliance discourse on nuclear deterrence.
First, maintaining a cogent nuclear deterrence narrative. Given the deterioration of the international safety environment, the continued ask for nuclear deterrence must conk on to endure stated clearly in addition to unapologetically—by NATO’s leadership but also past times national governments. Attempts to delegitimize nuclear deterrence volition non succeed equally long equally allies remain united in addition to ship the same message. NATO allies should also conk on to emphasize the ask for a supporting a nuclear infrastructure that is both prophylactic in addition to secure.
Second, retaining a strong commitment to non-proliferation in addition to arms control. NATO should non cede the moral high Earth to initiatives that delegitimize Western defence policies spell non seriously affecting “managed democracies” such equally Russia. While allies ask to rest united inwards their criticism of the treaty to ban nuclear weapons, their draw solid commitment to non-proliferation remains indispensable. Gradually reducing the salience of nuclear weapons, equally foreseen inwards the NPT, would demonstrate that allies remain committed to putting inwards house the atmospheric condition for a nuclear-free world.
Third, reaffirming extended deterrence. The United States’ nuclear umbrella for its allies remains a major pillar of the global safety order in addition to an of import non-proliferation tool. Above all, it is a brilliant manifestation of Europe in addition to North America considering themselves equally ane unmarried safety space. Consolidating extended deterrence must thus remain a NATO priority. This includes maintaining the appropriate military machine arrangements inside NATO (such equally dual-capable aircraft in addition to other agency of ensuring the broadest participation of non-nuclear allies inwards the nuclear deterrence mission), but also the persistent 24-hour interval of the month amid allies on nuclear strategy in addition to arms control.
Given the paradox of a Earth inwards which nuclear deterrence volition endure both to a greater extent than necessary in addition to to a greater extent than contested, NATO allies must walk a fine draw of stressing the ongoing importance in addition to legitimacy of nuclear deterrence without trivializing its technical risks in addition to moral dilemmas.
