Nuclear Weapons

Say WHAT? — A case of low-yield nuclear thinking

By Thomas Gaulkin, February 14, 2019

Can a small nuclear weapon really make the world safer?

The 2018 Nuclear Posture Review reaffirmed the Trump administration’s commitment to the broad (and costly) modernization of the nuclear weapons complex. But it also introduced two new weapons, one of which, the W76-2, is rolling off the assembly line in Texas right now.

That so-called “low-yield” nuclear warhead may soon be carried on some or all of the 14 active US Navy nuclear ballistic submarines that form one leg of the nuclear deterrence triad (the two other legs being US Air Force bombers and ground-launched intercontinental ballistic missiles). Former Secretary of Defense Mattis told Congress last year, “I don’t think there is any such thing as a ‘tactical nuclear weapon.’ Any nuclear weapon used any time is a strategic game-changer.” And a long list of experts, including the chairman of the House Armed Services Committee, say these kinds of “small” warheads increase the likelihood that nuclear weapons will be used—and full-scale nuclear war will follow.

So why is the United States building them?

In this installment of “Say WHAT?”—the Bulletin video series that casts a clear eye on fuzzy policy—we ask nuclear weapons expert Sébastien Philippe what he thinks about the latest nuclear craze. Watch above and subscribe on YouTube.

  • The move to much smaller yields is indeed worrisome, but some of the things said about it don't exactly cast a clear eye on the problem. Yes, smaller yields probably increase the chance of use, although we have no idea by how much. What if instead the move had been to increase yields by a large factor? Critics would be saying that the administration was increasing the horror of nuclear war. That would also be true, although by the same logic it would be reducing the chance of nuclear war. Should we conclude that we now have warheads with exactly the right yields? Hardly likely, nor does the concept even have any meaning. The truth is that we have no idea whether any of the theorizing about the possible use of nuclear weapons makes any sense. The real problem about the current move is not the lowered yield level, but what lies behind it. The suspicion, justified by the administration's swagger, is that what is really behind the reduction is a willingness to brandish nuclear weapons to subdue others. However justified by some strategic theory, this is toying with disaster. The significance of a yield reduction would be quite different if, out of concern for the destructiveness of nuclear war, the administration sharply reduced the yields of all our warheads. Or, better still, if it worked toward achieving universal agreement to eliminate the weapons altogether. That is the end, however unrealistic it may look today, toward which criticism would most usefully be directed. It is the only way out of our nuclear predicament.

  • You ask "Can a small nuclear weapon really make the world safer";

    This question is passable among lay people. This question is inexcusable on a specialist site like "Bulletin of Atomic Scientists"! Thus proving that America loses critical thinking skills by the minute. The empire is doomed if there is only group think and blind acceptance of press releases from on high.

    As to the question, ask yourselves: you have all lived through "cold-war detente" as Rand consultants have coined the phrase. What improved?

    Russia still has nuclear weapons, US still has nuclear weapons. Is the world safer? While Russian weapons remain pointed at the US, the US has invaded Iraq twice, attacked Panama, Somalia, Balkans, Remains permanently in Afghanistan, continues a raging passive-aggressive in-your-face stance vs Russia, has destroyed Syria, Yemen, ready to breach Venezuela, uses N. Korea as captive side-show, continues to proliferate via Nato, and belligerence is higher not less than the cold war.

    How did detente keep the peace? So the answer to this is low yield?

  • If one believes we would use a low yield device against Russia they are deluded. These devices are being created and directed toward two current targets, North Korea and more to the point Iran. These devices could be deployed with little collateral damage to neighboring countries. These devices would be used against Iran to destroy their perceived program and their weapons research facilities. This deployment against Iran would send a strong message to North Korea without the fear of escalation with China.

    the lower yield devices will reduce size of warhead and enable it to be deployed in hypersonic missiles and drones which can orbit a given theater for extended periods. This gives an implied threat to all countries not in step with American policy.

  • The world as gone mad, it's just a matter of time before someone presses the big red button, then it's back to Me cave man.
