Even a casual student of American politics must wonder what evangelicals are doing at the vanguard of a new movement toward the elimination of nuclear weapons. After all, the anti-Communism of a previous generation of evangelicals frequently left them opposed to more liberal, mainline brethren in their support for a robust Cold War deterrent.
And yet the Two Futures Project (2FP), a confessional Christian effort for the abolition of nuclear weapons, debuted publicly this year with endorsements from evangelical leaders across the political and theological spectrum.
Fueled primarily by a rising generation of Christians who are unencumbered by Cold War divisions, we have just launched a coast-to-coast speaking tour that will take our message to thousands of Christians at some of the most prominent churches and venues in the country.
A Singular Moral Imperative
The reason that most 2FP supporters get on board is not because they see nuclear disarmament as a stand-alone moral imperative.
Rather, the singular moral imperative concerning nuclear weapons is their non-use. Leaving aside the obscurantist and obsolete nuances of counter-force targeting, nuclear weapons are built to kill lots of people indiscriminately–an action defined as categorically immoral by the Christian Just War framework.
And, in the post-Cold War, post-9/11 era, the elimination of nuclear weapons has become the only policy capable of permanently preventing nuclear conflict.
It wasn’t always this way. During the Cold War, advocates of a robust deterrent and advocates of disarmament could both make a good-faith claim to the moral high ground, because each saw their favored policies as the best way to maintain the nuclear peace.
Today, however, everything has changed. The old ambiguities are gone. We now face only two eventual outcomes: a world without the Bomb or a world devastated by its use.
That’s why Evangelicals are supporting the disarmament agenda.
Tomorrow Needs Us Today
Our present situation owes its moral clarity to the fact that the long-term security benefits of nuclear nonproliferation–preventing the spread of nuclear weapons–are linked by treaty obligation to good faith progress on nuclear disarmament.
If the existing nuclear powers insist on an indefinite two-tier system of nuclear haves and have-nots–preaching plutonium temperance from the atomic barstool–proliferation crises like North Korea and Iran will continue to arise with increasing frequency and severity. Other nations, unwilling to be permanent second-class world citizens, will build the Bomb.
The increased danger of regional nuclear conflict will be bad enough. But worse, as bomb-quality nuclear material spreads, the question of a terrorist group acquiring the Bomb will change from “whether” to “when.” The laws of nuclear deterrence do not apply to a group that cannot be bombed back.
That’s why the weapons that the nuclear powers rely upon for their deterrent value will, eventually, create the very situation in which deterrence is undone.
The alternative–a world free of nuclear weapons–is neither easily nor immediately attainable. But even if we can’t chart a course all the way to zero, working in the right direction will make the world safer in the process. For example, international consensus on the desirability of a nuclear weapons-free world permits a stronger response to the unacceptable threat of a nuclear Iran.
I’ve found that evangelicals readily respond to the vision of a nuclear-free world–and the concrete steps needed to get there–laid out by former Cold Warriors like George Shultz, Sam Nunn, and others, as well as the nonpartisan supermajority of security elite who agree with them. The policies these experts lay out have formed the backbone of the Obama administration’s nuclear vision–a nonpartisan security agenda that should unite Americans across political lines.
Two Futures, One Choice
Often, the language of morality is set in opposition to the language of possibility. Moral imperatives, and religious crazies like me who atavistically believe that a living God put them in place and still cares a great deal about them, establish the horizon against which the “realists” get real work done.
But in the post-Cold War, post-9/11 era, there is a straight line between the theological prohibition against using the Bomb and the only prudential way to achieve this goal.
In other words, a world without nuclear weapons is something we must do for our security. It’s something we can envision, technologically. And it’s something we ought to do in accord with our deepest moral commitments to prevent the loss of innocent life.
Must, can, and ought: a powerful nuclear triad, indeed.
