Deterrence and Conventional Military Forces

The Role of Nuclear Weapons
in a Conventional Force-Dominant Deterrent

by Gary L. Guertner

The National Military Strategy 1992 states that the purpose of nuclear forces is "to deter the use of weapons of mass destruction and to serve as a hedge against the emergence of an overwhelming conventional threat." [6]

The dilemma confronting the United States is still the same classic problem that confronted strategists throughout the cold war. Nuclear weapons fulfill their declared deterrence function only if they are never used. Yet, if everyone knows that they will never be used, they lack the credibility to deter. The most credible means to resolve this dilemma is through a combination of declaratory policies and military capability that emphasizes the warfighting capabilities of conventional forces with strategic reach. [7]

There is, however, a potential paradox of success if aggressive Third World leaders believe that only weapons of mass destruction can offset U.S. advantages in conventional military power. Under such circumstances, theater nuclear weapons can have important signaling functions that communicate new risks and introduce greater costs for nuclear aggression that inflicts high casualties on U.S. forces or on allied countervalue targets.

Nuclear signaling can take the form of presidential or DOD declarations that U.S. ships deploying to a hostile theater of operations have been refitted with nuclear weapons carried by dual-capable aircraft (DCA) and Tomahawk Land Attack Missiles(TLAM). [8] Deployment options alone can playa critical role in the strategic calculus of aggressors who possess uncommitted nuclear capabilities.

The role of strategic nuclear forces is also directly related to the problems of reorienting the National Military Strategy from a global to a regional focus. The first problem is determining the force structure after the combined reductions of the START Treaty, unilateral initiatives, and reciprocal arrangements with the Russian Republic. The results will be dramatic cuts in U.S. strategic forces from some 12,000 strategic warheads to approximately 4,000 or less. [9]

These cuts are prudent responses to the collapse of the Soviet Union, and give us a long-sought opportunity to pull back from the nuclear brink where we so often found ourselves during the cold war. Moreover, these reductions fulfill our obligations under the Non Proliferation Treaty (NPT). They should be accompanied by strong U.S. endorsements of the treaty and support for the strengthening of the nonproliferation regime as we move toward a critical NPT review conference in 1995.

The credibility of U.S. support for nonproliferation will also be affected by the declaratory policies and targeting strategy for a smaller strategic nuclear force structure. The most comprehensive review of the problem to date suggests that we could be moving in the right direction provided that the strategic role of conventional forces dominates future planning. A report by the Joint Strategic Target Planning Staff Advisory Group, chaired by former Secretary of the Air Force Thomas C. Reed, recommends major changes in the Single Integrated Operational Plan (SIOP).

The cold war SIOP contained carefully calibrated strike options against the former Soviet Union. In its place, the panel recommends an Integrated Strike Employment Plan (ISEP) with a "near real time" flexibility to cover a wider range of targets with a smaller force structure. The proposal identifies five categories of plans: [10]

  • Plan Alpha is a conventional force option against selective strategic targets of "every reasonable adversary."

  • Plan Echo is a nuclear option for theater contingencies or "Nuclear Expeditionary Forces."

  • Plan Lima is a set of limited SIOP-like nuclear options against Russian force projection assets.

  • Plan Mike is a more robust version of Plan Lima with graduated attack options in the 10s, 100s, and 1000s.

  • Plan Romeo is a strategic nuclear reserve force (SRF) to deter escalation, support war termination, and preclude other nuclear powers not directly involved in an ongoing crisis from coercing the United States.

    In their current form, these recommendations are excessive and favor a nuclear force structure that is not well suited for credible deterrence in the new world order. If they were misinterpreted as official policy, the United States could be accused of a double standard in declaring the value of nuclear weapons at the same time that it was asking others to foreswear them.

    In the case of the former Soviet Union, U.S. targeting policy should be muted. Prudence dictates that advantage be taken of every opportunity for mutual reductions of force levels and confidence-building measures such as lower alert rates, improved command and control structures, and cooperative steps to improve the safety of nuclear storage, transportation, and destruction procedures. [11]

    Russia will remain a nuclear power with a potential to threaten the United States and its allies. On the other hand, it is no longer the center of a hostile global movement or the leader of a powerful military alliance threatening Europe with overwhelming force deep in its own territory. Russian behavior is leveraged more by its need for Western aid and technology than by U.S. military capabilities. It is difficult to conceive credible scenarios in which even the most reactionary great Russian nationalist could find in nuclear weapons the tools that could be used against the West in preplanned ways to coerce concessions or that might tempt revisionist leaders to adopt reckless and inflexible positions.

    The United States will and should, along with its British and French allies, retain nuclear options, but it is premature in the extreme to plan robust nuclear attacks against the "force projection assets" of a state that is struggling for democracy and economic reforms. [12]

    Even though the United States may be a benevolent superpower, the political impact of global nuclear targeting is more likely to stimulate rather than deter nuclear proliferation. An alternative set of declaratory policies that are consistent with nonproliferation include commitments to deep cuts in nuclear forces coupled with a defensive strategy of direct retaliation against nuclear attacks on U.S. territory. Direct retaliation is one of the few credible missions for strategic nuclear forces in the post-cold warworld. Extending deterrence should be a function of conventional forces (the option embodied in Plan Alpha above).

    Global retargeting by nuclear forces is an unfortunate concept that is more likely to put American interests at risk in the long run. Marshal Shaposhnikov, Commander-in-Chief of the Russian Armed Forces, struck a more positive image in his correct observation that retargeting frightens people. It is better, he said, to discuss "nontargeting," which lowers the level of alert to "zero flight assignments of missiles." [13]

    The Marshal's formulations are too vague to serve as the basis of national policy. Nevertheless, his point should not be dismissed. The objectives of national military strategy are more likely to be achieved through the implicit flexibility to respond to nuclear aggression from any source rather than explicit declarations of global nuclear targeting. Many regional crises may be precipitated by the proliferation of nuclear weapons and ballistic missiles. U.S. strategy will, therefore, require a delicate balance not to give incentives to that very threat. A reassuring posture, in the eyes of regional actors and global partners, will require reexamination and "denuclearization" of deterrence in a new multipolar world.

    Finally, and above all, this study's primary purpose has been to recommend the option of using modern conventional forces for strategic purposes. A reliance on offensive nuclear weapons carries enormous risks that brought us to the brink of war during several cold war crises. The American public has every right to expect that the cold war's principal legacy of danger not be deliberately extended into the new world order.

    ENDNOTES

    [1] These strategic concepts are drawn from The National Military Strategy 1992, released by the Chairman of the Joint Chiefs of Staff in January 1992. Some have been narrowed in scope for ease of analysis. For example, the NMS lists strategic deterrence and defense as one of the four foundations on which our strategy is built. This study narrows this strategic concept to conventional deterrence and theater defense.

Ironically, the administration's pledge to support growing UN peacekeeping activities is under attack by members of Congress because of a long-standing agreement that makes the United States responsible for 30 percent of the cost of every operation. Japan and Western Europeans could conceivably relieve part of the perceived inequity, but Congress should also examine these costs in the larger context of collective security and global stability.

    [7] A major thesis of this study is that conventional deterrence must occasionally give way to conflicts that demonstrate capabilities, thereby strengthening deterrence for a new phase of stability. The bombing of Hiroshima and Nagasaki had much the same effect on nuclear deterrence.
    [8] President Bush's unilateral initiatives in September 1991 eliminated ground-launched tactical nuclear weapons and withdrew them from surface ships and submarines. Some sea- based weapons are scheduled for destruction. Others are in storage from where they can be redeployed for the "signaling" purposes advocated here.

    [11] These latter steps are well underway. Congress allocated $400 million to assist Russian efforts to transport, store, and destroy nuclear weapons, and on March 26, 1992, the State Department announced the appointment of Retired Major General William F. Burns, former Director of the U.S. Arms Control and Disarmament Agency, to head the U.S. delegation on Safety, Security, and Dismantlement of Nuclear Weapons (SSD Talks). Moscow has agreed on U.S. assistance in the production of containers for fissile material from dismantled nuclear weapons, conversion of rail cars for secure transport, construction of storage facilities, training in nuclear accident response, accounting procedures, and ultimate disposition of enriched uranium and plutonium. See Department of State Press Release, March 26, 1992.
    [12] Open discussions of nuclear targeting in the press were followed by equally controversial reporting of threat scenarios that were developed in the Office of the Chairman of the Joint Chiefs of Staff. These scenarios included a hypothetical NATO counterattack if Russia invaded Lithuania. There is virtually no support in NATO or in the U.S. Congress for such a course of action. However, the scenario does raise the question of what the United States should do in the event of a Russian-initiated civil warto reunite the former Soviet Union. Russian nationalists could indeed threaten nuclear retaliation against Western intervention. History suggests, however, that Western response would be political and economic, but not military, thus making nuclear threats irrelevant. "Threat" scenarios are discussed by Barton Gellman, "Pentagon War Scenario Spotlights Russia," The Washington Post, February 20, 1992, p. A1.
