President Obama hosted an international conference a couple of weeks ago on measures to tighten controls on the spread of nuclear weapons and possible theft of nuclear materials by terrorist groups.
This harks back to an early theme of his Presidency whereby he set the goal of a sharp reduction of the world’s inventories of these weapons.
Yet, a few months back Obama announced a $1 trillion program to upgrade the American nuclear arsenal. What’s going on ?
This vast expenditure for no apparent strategic purpose has generated little debate whether within the Obama administration, political circles or the public. This fits a by now recognizable pattern: critical decisions are taken on matters heavy with consequence without explanation of why that course of action is chosen and it then goes unremarked by the politicos and media.
That double failing is making a mockery of our supposedly democratic governance. Furthermore, it allows to slip under the radar costly — potentially dangerous — initiatives that cannot hold up under scrutiny.
We have 70 years of history with nuclear weapons. The accumulated experience includes decades of Cold War dealings with the Soviet Union, nuclear arms spread to nine other countries, the refinement of our thinking about all aspects of their strategic role, and rigorous exercises on the logic of deterrence, of coercion, and compulsion. No subject has been received as concentrated critical examination.
The understanding and wisdom acquired, though, seems to have largely eluded those who have chosen to head down the path of elaborating our nuclear capabilities and doctrines for their use. Why? We haven’t been told. However, we have learned from leaks what are the features of this massive new nuclear program. (For details see “As U.S. Modernizes Nuclear Weapons, ‘Smaller’ Leaves Some Uneasy“ WILLIAM J. BROAD and DAVID E. SANGER The New York Times JAN. 11, 2016)
One, it aims to design and to build a class of small (in size and yield) bombs in the 5-10 kiloton range. Incorporating highly sophisticated engineering, it theoretically would be possible to adjust the “yield’ depending on the target and the purpose.
Two, these nuclear munitions could be packaged as precision-guided weapons deliverable from either stationery missile platforms or aircraft that would launch them as they currently do warheads with conventional explosives.
Three, these refined capabilities would enable them to be used against hardened targets such as underground nuclear facilities, against an enemy’s military installations or against other high value targets.
Four, by implication these are “first-strike” weapons; that is to say, their value is not to deter another nuclear armed state by threatening devastating retaliation, but rather to accomplish a mission either related to a conventional conflict or to eliminate an objective judged to pose a potential threat.
Thus, this “new age” nuclear force represents a radical departure from what has become the ‘no first use” principle of nuclear strategy — in practice if not in treaty.
To place this radical development in perspective, it is essential to remind ourselves of a few basic truths distilled from our collective experience of the nuclear era.
1. When we speak of an encounter between two nuclear armed states, the weapons’ primary utility is to deter the other. The risk and consequences of nuclear war are so great as to outweigh any possible advantage in trying to actually use them as part of a military strategy.
This holds for all binary pairs of nuclear states: India-Pakistan, Israel-Iran (conjectured). The resulting condition of Mutual Assured Destruction (MAD) is stable when the following conditions are met: both sides have the capacity to withstand a first strike while retaining the means to deliver a nuclear riposte; and when there is the will to do so. No one has ever thought of testing the credibility of the latter.
The exact modalities of the countries’ nuclear arsenals have no bearing on this fundamental logic. It manifestly has been absorbed by everyone who has been in a position to order a nuclear strike. No civilian leader (or military commanders with a few exceptions) with the authority to launch a nuclear attack ever believed that the result would be other than a massive exchange – mutual suicide for those with large arsenals. This did not encourage risk-taking at lower levels of conflict. Just the opposite – for fear of escalation.
2. That raises the question of whether Washington has an interest in keeping open the option of making first use of nuclear weapons against Iran or North Korea. It is not at all obvious that these doctrinal nuances have any practical meaning other than as post hoc rationales for decisions taken for different reasons. Preemptive nuclear strikes are highly risky since one never knows with certainty that they will disarm an enemy and prevent them from responding in other highly disagreeable ways. Think of 20,000 North Korean artillery pieces trained on Seoul. Think of Iran’s several opportunities to wreak havoc in the Gulf.
3. First-use — even as doctrine — also sets dangerous precedents. It weakens the nuclear taboo entrenched since 1945, and it thereby heightens anxiety in a manner that increases the risk of accidental or miscalculated use.
4. The smaller the caliber of nuclear arm, the greater the temptation to devise military doctrines for their use — despite the experience of the past 70 years and the logic outlined here. So-called Tactical Nuclear Weapons (TNWs) are inherently dangerous.
TNWs have a long history — both as to their inclusion in arsenals and in strategic thinking. This history, though, is now being ignored, whether neglect is due to
inattention or to intentional dissimulation. The net effect is the same.
There was a military reason why the United States was attracted to TNWs. In the context of Mutual Assured Destruction — or mutual dissuasion — wherein the resort to nuclear weapons leads inexorably to massive exchanges amounting to total destruction on both sides, the one with superior conventional forces possesses a theoretical advantage. That is to say, it could overwhelm the weaker party, present it with a fait accompli, and expect that there would be no nuclear riposte since that would mean mutual destruction. In theory.
The seeming answer: TNWs which, it was hoped, could be used to counter a massive conventional attack without triggering an all-out nuclear war. The risk of that happening, in turn, deters the would-be conventionally superior attacker – as does the fear of uncontrolled escalation.
However far-fetched, this was official American/NATO strategy in Europe from 1960 until the Cold War’s end. Our strategy, our force configuration, our contingency plans in Europe were all formed by this concept.
So what is the point of constituting a high-tech nuclear force now to be centered on TNWs, precision-guided munitions and low yield warheads? There is no conventionally superior, or equal, potential adversary out there. The United States enjoys conventional superiority over all conceivable enemies.
So, the scenarios are quite different. Pentagon military planners and their obedient White House “overseers” obviously have Iran and other possible “rogue” states in mind – that is to the extent that strategic considerations of any kind lie behind the program’s development.
For the driving forces are more likely to have been a dedication to technological along with powerful bureaucratic interests. Let us assume, for the purpose of this logical exercise, that whatever strategic thinking has been done was not simply post-hoc justification.
Can the inferior nuclear state deter the superior nuclear state from launching conventional attacks? We do not have much data on this — especially since there is no case of the superior state trying to do so. Would an Iran with a rudimentary nuclear arsenal be able to deter an American or Israeli-led assault a la Iraq by threatening troop concentrations and/or fleet elements in the Persian Gulf?
We certainly can say is that it would heighten caution. An inferior nuclear state might wish to instill anxiety that its weapons could be activated accidentally at the height of a crisis – thereby deterring a superior (nuclear and/or conventional) antagonist from pressing its advantage.
A similar logic points to cultivating an image of being ‘irrational.’ Would the United States have invaded Iraq if it believed a ‘crazy’ Saddam had 3 or 4 nuclear weapons? Would it consider aggressive action against Iran if it believed the ‘mad Mullahs’ in possession of 3 or 4 nuclear weapons? Not sure. But what bearing would upgraded TNWs have on this calculus? None.
If the inferior state (e.g. North Korea) has the ability to deliver a nuclear weapon against the superior’s homeland, that cautionary element grows by several factors of magnitude. Again, in theory. Again,TNWs add nothing to deterrence.
A second question: Can the nuclear state provide a credible deterrent umbrella for an ally that is conventionally inferior to a superior armed enemy? (Western Europe facing the Red Army; Saudi Arabia facing Iran circa 2040). The NATO and South Korea experience says ‘yes.’ That is, if the stakes are highly valued by the state providing the “nuclear umbrella.” Again, the risks of escalating to nuclear exchanges have a conservative effect on everyone. Two things deter: certainty; and total uncertainty.
Here is one general thought about extended deterrence as a ‘generic’ type. Throughout the Cold War years, the United States and its strategically dependent allies wrestled with the question of credibility. Years of mental tergiversations never resolved it.
For one intrinsic reason: it is harder to convince an ally than it is to convince a potential enemy of your readiness to use the threat of retaliation to protect them. There are two aspects to this oddity. First, the enemy has to consider the psychology of only one other party; the ally has to consider the psychology of two other parties.
Then, the enemy knows the full direct costs of underestimating our credibility and, in a nuclear setting, will always be ultra conservative in its calculations. By contrast, the ally that has not experienced the hard realities of both being a possible target of a nuclear attack and the possible originator of a nuclear attack cannot fully share in this psychology.
Is this last observation a point in favor of developing a more refined first-strike capability? No. For one thing, given the disproportion of forces, there is no conceivable gain from the conjectured fine-tuning. For another, the risk of nuclear proliferation in the region is very low.
So why are we pushing ahead with a hugely expensive nuclear weapons program that serves no evident strategic purpose? One conceivable answer is that we are just “keeping up with the Joneses.” But there are no Joneses anywhere out there. Greater efficiency? Nuclear weapons are unique in that they serve their purpose when they are not used — just sitting in the garage.
Small improvements in potential performance, therefore, offer no benefit to the owner. Another, more realistic explanation is that we want to prove to ourselves that we “can” do it. That is also why we climb mountains. In this case, there is something of a technological imperative involved as well.
If advances in science and engineering hold out the prospect of our being able to do something technologically impressive, then we are tempted to demonstrate that we are up to the challenge. Much of innovation in the post-modern era is of this nature, i.e. technological feats of uncertain practical benefit.
To nuclear weapons, we should add the macho enhancement effect. That mind-set includes an element of faddism. We cultivate a desire for a product after the fact of its being manufactured. Smart Watches, for an example. Or, self-driving cars.
Post-hoc demand creation likely plays a role in maintaining impetus behind the $1 trillion nuclear arms build-up. Once the military people and defense “strategists” fix their minds on ultra-capable, precision-guided and customized nuclear missiles and bombs, they come up with ends to which they might be put.
And let’s not forget that for some the idea of being able to launch a smart, nuclear tipped missile down an imagined Iranian tunnel to where critical projects are located is thrilling. Or, just think what might have happened had we such masterful technology when Osama bin-Laden was holed up in a Toro Bora cave in December 2001.
I guess that by some abstract thinking it could have compensated for the obtuseness of General Franks in refusing to send up Special Forces (for fear of casualties) or the ineptitude of the CIA/NSA in losing track of him for a decade until a walk-in gave away his location.
The titanosaur sized price for that dubious gain hardly seems worth it when the much cheaper alternative is the promotion of qualified generals and Intelligence officials. The pity is not realizing at the outset that this greatest of all dinosaurs is actually a White Elephant.
