For Better or For Worse: The Future of C3I Entanglement

The future risks of inadvertent escalation due to entangled conventional and nuclear systems will depend on broader geopolitical developments, advances in non-nuclear weapons, changes in states’ military doctrines, and whether states can implement risk mitigation measures.

Nuclear Policy

The Nuclear Policy Program aims to reduce the risk of nuclear war. Our experts diagnose acute risks stemming from technical and geopolitical developments, generate pragmatic solutions, and use our global network to advance risk-reduction policies. Our work covers deterrence, disarmament, arms control, nonproliferation, and nuclear energy.

In a conventional conflict between the United States and China or Russia, each belligerent might attack the other’s command, control, communication, and intelligence (C3I) capabilities to gain a warfighting advantage. However, because a number of C3I assets are dual-use, such attacks would degrade the target’s nuclear command-and-control system, creating serious risks of inadvertent escalation. Looking forward, at least four factors will influence the severity of the risks created by such entanglement.

First, geopolitical developments will have indirect effects, including altering (for better or worse) the likelihood of war. Second, improvements in nonnuclear weapons, such as the development of long-range hypersonic gliders, could increase the threat posed to nuclear C3I capabilities. Moreover, because early-warning assets involved in nuclear operations might be able to track such weapons, they could become more likely to be subject to attack. Third, states’ conventional or nuclear doctrines could change, including by increasing or reducing the role accorded to attacks on C3I assets. Finally, unilateral or cooperative risk-mitigation measures could be implemented. Unilateral measures are the most promising under current political circumstances and could be as simple as raising awareness of the risks associated with entanglement within defense and military establishments.

    Demystifying the Nuclear Threshold

    The nuclear weapons threshold is increasingly important for proliferation strategy and policy. Policymakers should better understand the implications of the threshold phenomenon in the current international security environment and plausible strategies to deal with the growing challenge that it presents.

    Nuclear Weapons and the Future of American Power

    It seems likely that, no matter what, the power of the U.S. nuclear arsenal will face erosion, not least in the credibility of its commitments to defend allies and the political durability of those alliances.

    President Lee Jae Myung: A Year in Power

    President Lee marked his first year in office after one of the most tumultuous periods in South Korean politics. Though Lee has enjoyed a high approval rating, a large majority in the National Assembly, and foreign policy victories, Lee and his party’s political fortunes depend on generating economic growth, learning the right lessons from the recent local elections, and managing contentious factional strife within his political base.

    Taking the Pulse: Is European Diplomacy on Iran Outdated?

    When the U.S.-Iran memorandum of understanding was announced, the UK, France, Germany, and Italy declared their readiness to help demine the Strait of Hormuz and lift nuclear sanctions on Tehran. But does Europe need new tools to recover a diplomatic role?
