- Abstract:
- Despite the overarching strategic priorities laid out by the Biden administration and initial indicators provided by the Department of Defense (DoD), it is unclear how the next National Defense Strategy (NDS) will prioritize threats and the primary role of the U.S. military. Will the DoD clearly preference China (and to a lesser extent Russia)? Or will it hedge and try to more equally meet the expanded list of threats detailed in the Interim National Security Strategic Guidance? Is the Pentagon’s priority to compete below the threshold of armed conflict, or is it to prepare to defeat a great-power adversary in a large-scale war to strengthen deterrence? Answering these questions is critical to developing a clear strategy that emphasizes the right priorities, activities, and resources. To consider the next defense strategy and the tradeoffs associated with different options, we developed three possible strategies—high-end deterrence, day-to-day competition, and full-spectrum competition—that alter the factors highlighted above and reflect the Biden administration’s stated priorities. Our analysis of the Fiscal Year (FY) 2022 budget indicates that the DoD is trying to do more than constrained budgets can support over the next few years and is moving toward what we term as a strategy of “full-spectrum competition.” It appears as if the Biden administration is pursuing a strategy that seeks to strike a balance between competing in the near term while still enhancing preparedness for great-power conflict, as well as hedging against a range of threats and mitigating risk over time. The forces and posture that are necessary for this competition are quite different from those that are needed to defend against a conventional fait accompli attack by China on Taiwan or Russia on the Baltics. It is unlikely that the United States can build a force that can achieve both of these objectives with the current topline. Our testing of the budget-constrained force associated with the full-spectrum competition strategy finds that it could not successfully fulfill its two primary aims: defeating sub-conventional aggression and Russian and Chinese gray zone tactics, and building a force capable of defeating a great-power adversary attack on its neighbor. Moreover, this strategy risks significant overstretch, the potential for long-term technological overmatch, and inadvertent escalation. The other two strategies focus on China, but day-to-day competition emphasizes the daily military contest with Beijing and the threat of sub-conventional conflict, while high-end deterrence focuses on defeating conventional aggression and achieving a long-term military technological advantage. The day-to-day competition strategy would lose a high-end conflict in East Asia and Europe; it also would fail to halt or overturn sub-conventional land grabs. The competition strategy bets that a large and visible force that actively contests daily military provocations will deter both sub-conventional and conventional aggression, even if the force is not capable of stopping either type of attack. The risk that this assumption fails grows over time because this strategy forgoes investments in advanced technologies, while China and Russia are rapidly seeking to wrest the military technological advantage from the United States. There are also significant escalatory risks associated with an approach that regularly and assertively contests Chinese and Russian forces. We conclude that it is unlikely that competition can be won by the military, even one optimized to face this challenge. More optimistically, our analysis suggests that it is possible to build a force capable of winning one big conflict and overturning sub-conventional aggression with this topline—but only if the department is willing to accept some near-term risk in competition, against other threats, and in other regions. The high-end deterrence strategy mitigates the temporal risk by making near-term improvements in combat capabilities, including expanding stockpiles of preferred long-range munitions, investments to improve the resiliency of U.S. posture in the Indo-Pacific and Europe, and additional investments in cyber and electronic warfare capabilities. It also relies on frontline allies and partners to be responsible for the daily competition. We assert that the high-end deterrence strategy is the best path forward, but it requires a better delineation and ranking of threats and responsibilities for the joint force and strategic discipline over the long run. Congress must also support this strategy and allow the Defense Department to make the hard choices, such as cutting capacity and retiring weapons systems, that are required to rebalance the force for this mission and to sustain its military technological advantage over the long run. Senior Pentagon leaders will need to partner with Congress to help them understand how specific changes are connected to higher order objectives. It is important to note that the FY22 budget is largely an inherited one and the Biden administration is making some significant investments that align with a high-end deterrence strategy. Nevertheless, the 2022 NDS and the FY23 budget will need to accept more risk and further prioritize to prepare the force for the most challenging and consequential threats. If the Biden administration does not make these hard choices or Congress refuses to support this strategy, the chasm between U.S. strategic and military objectives and the costs of achieving them will only grow significantly. Trying to do too much is a risky business that could result in the United States losing its military technological edge and, ultimately, a war against a great power.
