deterrence

The Ukrainian crisis created by Russia’s aggressive adventurism has sparked much soul-searching among NATO’s commanders, western lawmakers and policymakers and the western defense world’s thinkerati. Should we bolster missile defenses in central Europe? What about the permanent US military presence in Europe? Has it gotten too small? Do we need to bolster America’s nuclear forces,… Keep reading →

CAPITOL HILL: On the day that China’s president took personal charge of his country’s new cyber body, pledging to make the People’s Republic of China a “cyber power,” the outgoing head of America’s Cyber Command laid out a clear red line that, if crossed, could lead to war. “If it destroys government or other networks,… Keep reading →

First thermonuclear bomb test

Bob Butterworth knows nuclear weapons. He know cyber weapons. He knows space. He knows intelligence. And Butterworth cares enough to take public risks, to speak plainly in hopes others will do the same and thus help the country find the best answers to tough problems. While the American public has little idea it’s happening, a… Keep reading →


Before his latest State of the Union speech, President Obama was widely reported to be ready to propose a significant reduction in nuclear weapons. Then North Korea conducted a nuclear test the day before the address. (The photo above shows Kim Jong-Un smiling after his country’s recent successful ballistic missile test.) In his speech, President Obama only committed the US government to work with Russia to “seek further reductions,” though the New York Times said before the speech that the administration aimed to cut as many as 700 of our 1,700 deployed nuclear weapons. One of America’s most highly regarded nuclear strategists argues below that nuclear deterrence works. James A. Blackwell, an Air Force official, posits that those who argue they are Cold War weapons of such tremendous power as to be unusable are demonstrably wrong. The Editor.

There is an unsettling paradox in much of the recent debate over nuclear weapons in this country. Some pundits, fixated on purging “Cold War thinking” from those of us with real-world responsibilities for nuclear deterrence, are themselves suffering from thoughts frozen in time. In the midst of this important debate, let me offer some examples of the new strategic concepts emerging from a new generation of deterrence thinkers.

The conventional wisdom is that a world with fewer nuclear weapons is inherently a better world. What we are discovering is that less is not less, less is different.

US policy has led in reducing nuclear weapons. At its peak in 1967, the US stockpile stood at a staggering 31,255 warheads. Just since 1991, we have disassembled more than 13,000 weapons, and in the past decade taken our stockpile – the total number of weapons — down from 10,526 in 2001 to 5,113 in 2010. Our nuclear weapons and delivery platforms now number an order of magnitude less than during the Cold War, and this policy continues — creating new conditions in the global nuclear balance.

In this new nuclear environment, potential adversaries are reaching conclusions we did not expect, and our allies and partners are more nervous about it than we want them to be. This new world of several contending nuclear powers behaves differently than the bi-polar world that preceded it.

Deterrence is no longer (if it ever really was) a rational actor systems model; it works as a mental model. It’s more like the “hot hand” rule in basketball – players do not keep mental statistics on who has the highest percentage shot for a particular game situation; instead they carry a moving mental image of who at that moment is on a streak and feed the ball to that player instinctively. The same kind of thing happens in crisis and conflict. Behavioral scientists call this “fast, frugal heuristics,” and are beginning to explore the empirical dimensions of this 21st century deterrence dynamic.

There are some surprising findings and insights.

First, just because no one has detonated a nuclear weapon in war since 1945, does not mean they are sitting idly by, with little purpose. Nuclear weapons are in fact “used” every day — not to win a war, but to deter any adversary from thinking they could get away with starting one. As budget pressures rise, many call for not spending more on weapons we cannot use in the kinds of conflicts most likely to occur – presumably counter-terrorism or conventional warfare. But a nuclear war is the conflict we need to make sure remains the least likely to happen.

Second, there is much new research on 21st century deterrence of rogue actors and terrorists. We now know that, during the 1991 Persian Gulf War, Saddam Hussein was persuaded that if he were to order use of chemical weapons against US troops, the US would have responded with tactical nuclear weapons.

Hussein had extensive discussions with his generals – lectures really – and injected that assumption into all their war planning. Such thinking likely resides within the decision-making processes of other states that face a similar calculus. There is merit in reinforcing such fears among others who would harm their neighbors. It turns out that terrorists, even suicide bombers, harbor visceral fears of nuclear weapons, fears that can be exploited to deter them from acting should they ever get one.

Islamic terrorists adhere to the Koran’s proscriptions against poisoning the earth with radiological effects and creating mass casualties among the innocent. Cyber and psychological campaigns can broadcast messages across terrorists’ own social networks to convey this narrative challenge to terrorists’ intent. Terrorist cells also fear failure, so technical sabotage, misinformation and deception can magnify doubt about the prospects for a successful detonation.

Third, US nuclear weapons serve as a powerful instrument of nonproliferation. Post-Cold War experience reveals that others, from Saddam’s Iraq, to North Korea, Libya, Iran and others, pursue nuclear weapons as the centerpiece of an asymmetric counter to the United States’ conventional military superiority. As every other nuclear power except the U.S. modernizes their nuclear weapons, and as the number of nuclear armed states continues to grow, our allies and partners who rely on our extended deterrent are increasingly motivated to consider obtaining their own nuclear arsenal. We must actively pursue a flexible strategy that allays such concerns among allies.

Some assert that a reliable nuclear deterrent does not require the ability to retaliate immediately, only the assurance that U.S. nuclear forces would survive any attack.

Aside from the fact that none of America’s nuclear triad is on “hair-trigger” alert, the reality of fewer nuclear weapons is that we cannot rely solely on a super-survivable second strike nuclear force that deters only by threatening retaliation. Such a posture could readily be perceived as threatening our intent to strike first. We must have a resilient nuclear arsenal that deters a nuclear strike in the first place.

No president would want to ask the American people to ride out a first strike and then trust him to order a retaliatory strike on behalf of the remaining fraction of our population. What the president needs is a nuclear force that would lead no nuclear armed state, faction or terrorist to conclude that it has less to lose by striking us first, even with just one or a few nuclear weapons. We must not give anyone cause to contemplate such a move.

This is a very different form of deterrence than the Cold War. No longer can we rely on the mathematics and purely rational models of nuclear exchange developed in the 20th century. We must understand human perception and decision-making. For 21st century deterrence, the value of first-strike stability is now at least equally important as maintaining an assured retaliation capability. Those of us in the new generation of strategic thinkers have liberated our minds from Cold War thinking to make sure that today, nuclear weapons are never used.

James Blackwell is special advisor to the Air Force’s assistant Chief of Staff for strategic deterrence and nuclear integration.

Since President Obama has declared Syrian use of chemical weapons a “red line” that line should mean something when it has been crossed. And the president better have a clear view of what his options are to change the situation when the “red line” is crossed.

But do we? Keep reading →


WASHINGTON: Cyberspace is an inherently unstable realm where traditional strategic concepts of deterrence and defense break down – and it’s the United States that has the most to lose from that instability, warns a forthcoming report from the Cyber Conflict Studies Association.

“The Cyber Conflict Studies Association’s two-year study has lead to the sobering conclusion that the current strategic cyber environment is fundamentally unstable,” said the report, previewed for the press today at the Atlantic Council in Washington, DC. (Click here to download). Cyberspace is “marked by an inability to establish credible deterrence.” It is so much easier to attack than to defend, and so difficult to figure out who attacked you, that attackers cannot be reliably deterred either by strengthening your defenses or by threatening retaliation.

Washington: When you oversee the U.S. nuclear weapons enterprise, there are a lot of things that can keep you up at night.

But figuring out how to sustain the industrial base that supports the U.S. nuclear arsenal, particularly as the Pentagon prepares to shrink that arsenal by thousands of weapons, is what has Strategic Command chief Gen. Robert Kehler tossing and turning. Keep reading →

Over the next 25 years or so, the United States plans to recapitalize its triad of submarines, bombers, and missiles that deliver strategic nuclear weapons, building new versions of these weapons to extend a 50-year-old force structure for another half century. Yet today’s strategic environment is not that of the 1960s, and tomorrow’s may differ even further, if only because of regional nuclear powers and non-state adversaries. Are the challenges of that environment best met by replicating, presumably with fewer weapons, a force structure intended to survive, at least in part, a massive Soviet attack? And is the thinking that produced the earlier plans the best way to approach future challenges?

A Hope, Not A Plan
The central concept underlying the current force structure, of course, is deterrence, an aspiration embraced in the nuclear era as a default option imposed on military planners by weapon technologies. Unable to prevent a comparably-armed enemy from destroying the United States, Americans could only hope to avoid being disarmed. What the surviving weapons would be used for is the subject of presidential guidance and has long been debated, but the ability to retaliate, whatever the targets, was thought to provide the best achievable response to mortal threats.
