- Abstract:
- Over the last decade, the most significant change in the international strategic environment has been the reemergence of a great power rivalry between the U.S. and its European and Asian allies on one hand and Russia and China on the other. This trend began in the second term of President Obama, with the Russian invasion of Crimea in early 2014 and the Chinese construction of a network of military bases in the South China Sea beginning around 2013. Since then, the trend has sharpened. The Russian invasion of Ukraine in February 2022 has locked the U.S. and its North Atlantic Treaty Organization (NATO) allies against Russia in a long-term struggle for the survival of Ukraine and future of European security. In Asia, tensions between Beijing and Washington have become worse, as both the Trump and Biden admіnistrations pursued economic measures against China, and as China appears to be building military options to unify Taiwan and the mainland by force. The reemergence of great power rivalry has important nuclear dimensions, increasing concerns about “strategic stability” – the nuclear balance among the great powers – and the risk of nuclear conflict. The Ukraine war has lowered the nuclear threshold. Russia has deployed tactical nuclear weapons in Belarus and threatened to use tactical nuclear weapons to discourage NATO intervention or assistance to Ukraine. The New Strategic Arms Reduction Treaty (New START) - the last remaining arms control treaty limiting U.S. and Russian nuclear arsenals - expires in February 2026, and Russia has refused U.S. offers to negotiate a new treaty as long as the U.S. is assisting Ukraine. In the meantime, Russia continues to develop an array of exotic nuclear delivery systеms intended to overcome U.S. missile defenses, including hypersonic reentry vehicles, nuclear-armed submarine drones, and nuclear anti-satellite weapons. China is pursuing an unprecedented nuclear build-up, including new strategic bombers, more advanced nuclear-armed submarines, and three new missile bases with more than 300 silos for solid fuel ICBMs with multiple reentry vehicles. According to U.S. Department of Defense estimates, China has more than 500 operational nuclear warheads as of May 2023 and will “probably have over 1,000 operational nuclear warheads by 2030” (U.S. Department of Defense 2023a). Like Russia, China is also pursuing hypersonic reentry vehicles, anti-satellite weapons, and strategic cyber operations. Some analysts fear that China’s nuclear build-up will make it more confident that it can deter U.S. intervention in the face of a Chinese invasion of Taiwan or increase the risk that a U.S.-China confrontation over Taiwan will escalate to nuclear use. To address the reemergence of great power threats, the U.S. has introduced the concepts of “tailored deterrence” and “integrated deterrence” into its nuclear doctrine. According to the Trump admіnistration Nuclear Posture Review, released in February 2018, The United States will apply a tailored and flexible approach to effectively deter across a spectrum of adversaries, threats, and contexts. Tailored deterrence strategies communicate to different potential adversaries that their aggression would carry unacceptable risks and intolerable costs according to their particular calculations of risk and cost (Office of the Secretary of Defense 2018). The tailored deterrence concept was also adopted by the Biden admіnistration in its October 2022 Nuclear Posture Review, saying, Central to U.S. deterrence strategy is the credibility of our nuclear forces to hold at risk what adversary leadership values most. Effectively deterring – and restoring deterrence if necessary – requires tailored strategies for potential adversaries that reflect our best understanding of their decision-making and perceptions (Office of the Secretary of Defense 2022). Building on the concept of tailored deterrence, the Biden admіnistration Nuclear Posture Review (NPR) also introduced the concept of “integrated deterrence,” which is based on the idea that traditional nuclear deterrence can be reinforced by non-nuclear capabilities. According to the NPR, The role of nuclear weapons is well established and embedded in strategic deterrence policy and plans. Non-nuclear capabilities may be able to complement nuclear forces in strategic deterrence plans and operations in ways that are suited to their attributes and consistent with policy on how they are to be employed. A pragmatic approach to integrated deterrence will seek to determine how the Joint Force can combine nuclear and non-nuclear capabilities in complementary ways that leverage the unique attributes of a multi-domain set of forces to enable a range of deterrence options backstopped by a credible nuclear deterrent (Ibid.).
