The Department of Defense has begun to ratchet up spending to recapitalize the U.S. strategic nuclear triad and its supporting infrastructure, as several programs move from research and development into the procurement phase.  The projected Pentagon expenditures are at least $167 billion from 2021-2025. This amount does not include the large nuclear warhead sustainment and modernization costs funded by the Department of Energy, projected to cost $81 billion over the next five years.

Nuclear forces require modernization, but that will entail opportunity costs. In a budget environment that offers little prospect of greater defense spending, especially in the COVID19 era, more money for nuclear forces will mean less funding for conventional capabilities. That has potentially negative consequences for the security of the United States and its allies. While nuclear forces provide day-to-day deterrence, the Pentagon leadership spends most of its time thinking about how to employ conventional forces to manage security challenges around the world. The renewed focus on great power competition further elevates the importance of conventional forces. It is important to get the balance between nuclear and conventional forces right, particularly as the most likely path to use of nuclear arms would be an escalation of a conventional conflict. Having robust conventional forces to prevail in or deter a conventional conflict in the first place could avert a nuclear crisis or worse.

NUCLEAR WEAPONS AND BUDGETS

For the foreseeable future, the United States will continue to rely on nuclear deterrence for its security and that of its allies (whether we should be comfortable with that prospect is another question). Many U.S. nuclear weapons systems are aging, and replacing them will cost money, lots of money. The Pentagon’s five-year plan for its nuclear weapons programs proposes $29 billion in fiscal year 2021, rising to $38 billion in fiscal year 2025, as programs move from research and development to procurement. The plan envisages a total of $167 billion over five years. And that total may be understated; weapons costs increase not just as they move to the procurement phase, but as cost overruns and other issues drive the costs up compared to earlier projections……….

Some look at these figures and the overall defense budget (the Pentagon wants a total of $740 billion for fiscal year 2021) and calculate that the cost of building and operating U.S. nuclear forces will amount to “only” 6-7 percent of the defense budget. That may be true, but how relevant is that figure?

By one estimate, the cost of building and operating the F-35 fighter program for the U.S. Air Force, U.S. Navy and U.S. Marines over the program’s lifetime will be $1 trillion. Amortized over 50 years, that amounts to $20 billion per year or “only” 2.7 percent of the Defense Department’s fiscal year 2021 budget request. The problem is that these percentages and lots of other “small” percentages add up. When one includes all of the programs, plus personnel and readiness costs as well as everything else that the Pentagon wants, the percentages will total to more than 100 percent of the figure that Congress is prepared to appropriate for defense.

OPPORTUNITY COSTS

The defense budget is unlikely to grow. Opportunity costs represent the things the Pentagon has to give up or forgo in order to fund its nuclear weapons programs. The military services gave an indication of these costs with their “unfunded priorities lists,” which this year total $18 billion. These show what the services would like to buy if they had additional funds, and that includes a lot of conventional weapons…………

These are the opportunity costs of more nuclear weapons: fewer dollars for aircraft, ships, attack submarines and ground combat equipment for conventional deterrence and defense…………..

If the United States and its allies have sufficiently robust conventional forces, they can prevail in a regional conflict at the conventional level and push any decision about first use of nuclear weapons onto the other side (Russia, or perhaps China or North Korea depending on the scenario).The other side would have to weigh carefully the likelihood that its first use of nuclear weapons would trigger a nuclear response, opening the decidedly grim prospect of further nuclear escalation and of things spinning out of control. The other side’s leader might calculate that he/she could control the escalation, but that gamble would come with no guarantee.  It would appear a poor bet given the enormous consequences if things go wrong. Happily, the test has never been run.

This is why the opportunity costs of nuclear weapons programs matter. If those programs strip too much funding from conventional forces, they weaken the ability of the United States and its allies to prevail in a conventional conflict—or to deter that conflict in the first place—and increase the possibility that the United States might have to employ nuclear weapons to avert defeat………

The United States and NATO still retain the option of first use of nuclear weapons. If the U.S. president and NATO leaders were to consider resorting to that option, they then would be the ones to have to consider the dicey bet that the other side would not respond with nuclear arms or that, if it did, nuclear escalation somehow could be controlled.

Assuring NATO allies that the United States was prepared to risk Chicago for Bonn consumed a huge amount of time and fair amount of resources during the Cold War…….

In modernizing, maintaining and operating a safe, secure and effective nuclear deterrent, the United States should avoid underfunding conventional forces in ways that increase the prospect of conventional defeat and/or that might tempt an adversary to launch a conventional attack. If Washington gets the balance wildly out of sync, it increases the possibility that the president might face the decision of whether to use nuclear weapons first—knowing that first use would open a Pandora’s box of incalculable and potentially catastrophic consequences.

GETTING THE BALANCE RIGHT IN THE COVID19 ERA

This means that the Department of Defense and Congress should take a hard look at

the balance. The Pentagon presumably has weighed the trade-offs, though it is not a unitary actor.  “Nuclear weapons are our top priority” has been the view of the leadership…….. The response to the virus and dealing with the economic disruption it has caused have generated a multi-trillion-dollar budget deficit in 2020 and likely will push up deficits in at least 2021. It would be wise now to consider the impact of COVID19. Having added trillions of dollars to the federal deficit, and facing an array of pressing health and social needs, will Congress be prepared to continue to devote some 50 percent of discretionary funding to the Department of Defense’s requirements? Quite possibly not. ………. https://www.brookings.edu/blog/order-from-chaos/2020/05/18/how-covid-19-might-affect-us-nuclear-weapons-and-planning/
