Of all Trump’s departures from tradition, none holds such potentially grave consequences as his decision to build up US nuclear weapons. After a decadeslong trend toward disarmament, Trump’s estimated $1.2 trillion upgrade would not only make current nuclear bombs more lethal but would add new long-range missiles to the US arsenal.
The rules of the game of war changed in the mid-20th century, when the US and the USSR both acquired the ability to instantly destroy the world hundreds of times over. At that point, survival and security became less a matter of technology and more one of psychology. The ostensible reason the US continues to keep nuclear weapons is to deter other nuclear states from using theirs.
The Trump administration’s plans are laid out in detail in a report, released in January, called the Nuclear Posture Review, which has come out every four years since the end of the Cold War. There, Pentagon officials argue that the US needs to build new weapons to keep up with similar efforts in Russia and China.
But again, what difference do Russia’s advances make when the US already has the ability to exterminate the human race in the most agonizing imaginable way?
And how do we know if America’s nuclear adversaries will be deterred more by the US continuing to disarm, or by starting a “new arms race,” as the New York Times described the Trump administration’s position? I posed that question to General George Lee Butler, who during the 1980s and early 1990s was commander in chief of the Strategic Air Command, and later, the United States Strategic Command -- the major US deterrence forces.
“The country, for years at the forefront of nuclear arms control and reductions, is undercutting that role,” he said of the new modernization plan, which will encompass all three legs of its so-called triad (land, sea and air) and include new families of weapons. “That not only breaks with the tradition of mitigating nuclear dangers, it sends a clear message that these weapons have utility beyond deterrence toward threats of coercion,” he said. “Such overt proclamations, coupled with the prospect of a wide-ranging display of military prowess through the streets of Washington, run counter to the very fabric of our democratic values.”
General Butler told me that in seeking deterrence, US nuclear war planners focused on what they thought was most precious to the Soviet leadership: their survival. Thus it was that at one point, the US aimed 400 nuclear weapons at Moscow alone -- each many times more powerful than those dropped on Hiroshima and Nagasaki. The goal, he said, was, in the case of a retaliatory strike, 100 percent assurance that the Soviet government would be destroyed in its entirety.
He came to realize, he said, that while deterrence was the ostensible point of such preparations, it’s a concept “ill-suited” to nuclear policy and strategy. “Nuclear deterrence assumes that you have a deep understanding of your foe’s capability and likely reactions under different circumstances,” he said.
As I listened to him, I came to understand that nuclear deterrence is a thin safety net made of guesswork and assumptions. If the goal of Trump’s modernization is deterrence, then there’s concern it will backfire. If the goal is something else -- such as actually using nuclear weapons in warfare -- then the Trump administration is proposing a moral and ethical departure that Americans would need to talk about.
Another Cold War insider turned deterrence skeptic is Daniel Ellsberg, a former Rand corporation strategist (and later leaker of the Pentagon Papers) and author of the recent book “The Doomsday Machine: Confessions of a Nuclear War Planner.” In a conversation with him last year, he said he changed his mind about the value of retaliating after a perceived nuclear attack when he recognized the potential for nuclear war to cause a global environmental catastrophe known as nuclear winter. Under those circumstances, using even a fraction of the Russian or US arsenal would amount to a suicide bombing.
Both General Butler and Ellsberg said they worried about the prospect of starting a nuclear war by mistake. There have been a number of risky incidents, the most notable being the Cuban Missile Crisis, when commanders aboard a Soviet submarine thought nuclear war had begun and almost fired a nuclear missile. General Butler said he became well-acquainted with the risk of accidental nuclear war while acting as principal nuclear adviser to the senior Bush and Clinton administrations. In exercises, the president would get about 10 minutes to decide whether to launch a retaliatory strike.
The benefits of Trump’s nuclear arms modernization are not obvious. We can’t afford to assume his administration is taking the best possible course of action to protect us. We have to keep asking questions. The stakes couldn’t be higher.Faye Flam
