Seventy-five years ago this month, the United States used the most powerful weapons developed until that time to attack the cities of Hiroshima and Nagasaki. Because the atomic bombings caused such extraordinary damage amid an already-disrupted wartime Japan, the number of people who died as a direct result of the attack can’t be pinpointed. Initial US military estimates placed the immediate death toll at 70,000 in Hiroshima and 40,000 in Nagasaki. Later independent estimates suggest that 140,000 people died in Hiroshima and 70,000 were killed in Nagasaki.

President Donald Trump’s chief arms control envoy last week acknowledged the possibility that the 2010 New Strategic Arms Reduction Treaty (New START) could be extended, but he added, “only under select circumstances.”  He then put down conditions that, if adhered to, will ensure the Trump administration does not extend the treaty.

New START and Extension

New START limits the United States and Russia each to no more than 700 deployed strategic missiles and bombers and no more than 1,550 deployed strategic warheads.  It expires by its terms on February 5, 2021 but can be extended for up to five years.  The Trump administration has adamantly refused to do that.

From the perspective of U.S. national security interests, extending New START is a no-brainer.  As confirmed by the State Department’s annual report, Russia is complying with the treaty’s limits.  Extension would keep Russian strategic forces constrained until 2026.  It would also ensure the continued flow of information about those forces produced by the treaty’s data exchanges, notifications, on-site inspections and other verification measures.

And extension would not force a single change in U.S. plans to modernize its strategic forces, as those plans were designed to fit within New START’s limits.

Russian officials, including Vladimir Putin, have raised New START extension since the first days of the Trump administration.  In 2017, Trump administration officials deferred on the issue, saying they would consider extension after (1) completion of a nuclear posture review and (2) seeing whether Russia met the treaty’s limits, which took full effect in February 2018.

Russia fully met the limits in February 2018.  At about the same time, the administration issued its nuclear posture review.  Yet, more than two years later, New START extension remains an open question.

On June 24, Amb. Marshall Billingslea, the president arms control envoy, briefed the press on his meeting with his Russian counterpart two days before in Vienna.  Asked about extending New START, Amb. Billingslea—never a fan of the treaty or, it seems, any arms control treaty—left the option open.  However, he described three conditions that will block extension.

China

Amb. Billingslea’s first condition focused on China, which he claimed had “an obligation to negotiate with [the United States] and Russia.”  Beijing certainly does not see it that way—saying no, no and again no—citing the huge disparity between the size of the Chinese nuclear arsenal and those of the United States and Russia.  China has less than one-tenth the number of nuclear warheads of each of the two nuclear superpowers.

To be sure, including China in the nuclear arms control process is desirable.  But Beijing will not join a negotiation aimed at a trilateral agreement.  What would such an agreement look like?  Neither Washington nor Moscow would agree to reduce to China’s level (about 300 nuclear warheads).  Nothing suggests either would agree to legitimize a Chinese build-up to match their levels (about 4,000 each).  Beijing presumably would not be interested in unequal limits.

This perhaps explains why, well more than one year after it began calling for China’s inclusion, the Trump administration appears to have no proposal or outline or even principles for a trilateral agreement.

For its part, Moscow would welcome China limiting its nuclear arms.  The Russians, however, choose not press the question, raising instead Britain and France.  Amb. Billingslea pooh-poohed the notion, but France has as many nuclear weapons as China, and Britain has two-thirds the Chinese number.  The logic for bringing in one but not the other two is unclear.  The question raises yet another hinderance to including China.

A more nuanced approach might prove more successful.  It would entail a new U.S.-Russian agreement providing for reductions beyond those mandated by New START.  Washington and Moscow could then ask the Chinese (and British and French) to provide transparency on their nuclear weapons numbers and agree not to increase their total weapons or exceed a specified number.  Much like his president, however, the arms control envoy does not appear to be into nuance.

Non-Strategic Nuclear Weapons

Amb. Billingslea’s second condition dealt with including in a new negotiation nuclear arms not constrained by New START, especially Russia’s large number of non-strategic nuclear weapons.  Again, this is laudable goal, but getting there will require much time and unpalatable decisions that the Trump administration will not want to face.

Russian officials have regularly tied their readiness to discuss non-strategic nuclear arms to issues of concern to them, particularly missile defense.  The Trump administration,  however, has made clear that it has zero interest in negotiating missile defense.

Even if Moscow severed that linkage, negotiating limits on non-strategic nuclear weapons would take time.  New START limits deployed strategic warheads by virtue of their association with deployed strategic missiles and bombers.  The only warheads directly counted are those on deployed intercontinental ballistic missiles and submarine-launched ballistic missiles.

By contrast, most if not all non-strategic warheads are not mounted on their delivery systems.  Monitoring any agreed limits would require new procedures, including for conducting on-site inspections within storage facilities.  This does not pose an insoluble challenge, but it represents new territory for both Washington and Moscow.  Working out limits, counting rules and verification measures will prove neither quick nor easy.

Verification

Amb. Billingslea earlier suggested some dissatisfaction with New START’s verification measures, though he did not articulate any particular flaw, and, as noted, the State Department’s annual compliance report says Russia is meeting the treaty’s terms.  Last week, he made verification measures for his desired U.S.-Russia-China agreement the third condition for New START extension. 

Verification measures are critical.  Treaty parties have to have confidence that all sides are observing the agreement’s limits or, at a minimum, that any militarily significant violation would be detected in time to take countervailing measures.  Working out agreement on those measures will prove a long process, even in just a bilateral negotiation, especially if it addresses issues such as stored nuclear weapons.  That is not just because of Russian reluctance to accept intrusive verification measures such as on-site inspection; the U.S. military also wants verification measures that do not greatly impact its normal operations.

Russian officials have reiterated their readiness to extend New START now.  Amb. Billingslea’s conditions will thwart extension for the foreseeable future.  That’s unfortunate.  By not extending New START, the Trump administration forgoes a simple action that would strengthen U.S. national security and make Americans safer.

Ending the moratorium would not advance U.S. security interests.  The United States has conducted about as many nuclear weapons tests as the rest of the world combined (and 30 percent more than the number conducted by the Soviet Union/Russia).  U.S. weapons scientists learned more from testing.  When I served as a diplomat at the American Embassy in Moscow in 1988, I accompanied a U.S. team to the Soviet nuclear test site at Semipalatinsk (in what is now Kazakhstan).  Our Soviet hosts showed us a vertical shaft for an upcoming underground test; it was about three feet in diameter.  A U.S. team member from the test site in Nevada, which the Soviets would visit the following month, commented that U.S.-drilled vertical shafts for nuclear tests typically were nine to eleven feet in diameter.  That maximized the area above the weapon for instruments that would gather a burst of data in the nanosecond before they vaporized.

The testing moratorium and the CTBT, if ratified and entered into force, would seem to lock in an area of U.S. advantage regarding nuclear weapons and nuclear effects.  Why would we want others to test and erode that advantage?

Up until the idea of gaining leverage with Beijing and Moscow arose, the primary possible reason for a return to testing was if it became necessary to confirm the reliability of a weapons type in the stockpile.  However, the National Nuclear Security Administration has overseen for 25 years the Stockpile Stewardship Program, intended to confirm that U.S. nuclear weapons are safe, secure and reliable without having to test them in a manner that produces a nuclear yield. To do so, the program uses supercomputers, modeling and tools such as the Dual Axis Radiographic Hydrodynamic Test Facility (think of the world’s most powerful X-ray device).

Each year, the commander of Strategic Command and the directors of the national nuclear laboratories at Los Alamos, Sandia and Lawrence Livermore certify the safety and reliability of the nuclear stockpile.  When I visited Los Alamos several years ago, the director told me that, as long as the Stockpile Stewardship Program was funded, he was confident that nuclear testing was not needed.  He added that, as a result of the program, weapons scientists had learned things about how nuclear weapons work that they did not and could not learn from testing nuclear weapons underground.

The smart thing for U.S. national interests is to continue the moratorium, ratify the CTBT, and press others to ratify so that the treaty can be brought into force.  The Senate failed to give consent to ratification in 1999, due to concerns about how to maintain the stockpile’s reliability without nuclear testing and about monitoring the treaty.  The Stockpile Stewardship Program, just in its beginning stage then, can now answer the first concern and has been doing so.

As for monitoring a test ban, U.S. national technical means have improved over the past two decades, and the Comprehensive Test Ban Treaty Organization has established the International Monitoring System with some 300 stations around the world.  It can detect underground nuclear explosions down to below one kiloton (the weapon that destroyed Hiroshima had a yield of 15 kilotons) as well as detecting tests in the atmosphere or ocean, both of which are banned by the 1963 Limited Test Ban Treaty.  Once in force, the CTBT also provides for an inspection mechanism.

As former Secretary of State George Shultz said in 2013, senators might have been correct not to consent to ratification in 1999, but given the Stockpile Stewardship Program’s development and enhanced monitoring systems, they would be right to vote for ratification now.

Conducting a nuclear test to bring China and Russia to the negotiating table will not work.  It will instead open the door for others to resume testing and close a nuclear weapons knowledge gap that favors the United States.  That will not make us safer or more secure.  It is an unwise idea that hopefully will continue to meet resistance within the U.S. government.

On May 15, the U.S. Ambassador in Warsaw, Georgette Mosbacher, suggested relocating U.S. nuclear weapons based in Germany to Poland. One hopes this was just a mistake by a political appointee unfamiliar with NATO nuclear weapons issues, not a reflection of official U.S. government thinking. Moving nuclear weapons to Poland would prove very problematic.

The U.S. Air Force maintains 20 B61 nuclear gravity bombs at Buchel Air Base in Germany (as well as B61 bombs on the territory of four other NATO members). Kept under U.S. custody, the bombs could, with proper authorization in a conflict, be made available for delivery by German Tornado fighter-bombers. This is part of NATO’s “nuclear sharing” arrangements.

The Tornados are aging, and the German Ministry of Defense is considering purchasing F-18 aircraft to continue the German Air Force’s nuclear delivery capability. That has reopened debate within Germany about the presence of U.S. nuclear arms there, with Social Democratic Party (SPD) parliamentary leader Rolf Mützenich calling for their removal.

On May 14, U.S. Ambassador to Germany Richard Grenell wrote an op-ed expressing concern about not “eroding the solidarity that undergirds NATO’s nuclear deterrent” and calling for the SPD to affirm Germany’s commitment to nuclear sharing. The next day, Ambassador Mosbacher entered the fray, with a tweet suggesting that U.S. nuclear weapons could be relocated to and housed in Poland.

If Germany wants to diminish nuclear capability and weaken NATO, perhaps Poland - which pays its fair share, understands the risks, and is on NATO's eastern flank - could house the capabilities here: https://t.co/VIzpHIgoUN

This is a truly bad idea.

First, moving U.S. nuclear weapons to Poland would be expensive. Relocation would require constructing special infrastructure, such as WS3 underground storage vaults, and other equipment to ensure their security. The vaults normally are located within specially hardened aircraft shelters. While not a budget-buster, U.S. and NATO militaries have far more pressing needs to shore up the alliance’s deterrence and defense posture.

Second, deploying the B61 bombs in Poland would make them more vulnerable to Russian preemptive attack in a crisis or conflict. Russia has deployed Iskandr-M ballistic missiles in Kaliningrad. With a range of up to 500 kilometers, these missiles could strike targets in almost all of Poland within a matter of minutes and with very little warning.

Buchel, by contrast, would have longer warning time of an attack, and aircraft flying from there at least begin their flights out of range of Russian air defenses. The two major Polish air bases — which host Polish F-16s that are not, in any case, nuclear capable — are located within range of Russian S400 anti-aircraft missiles deployed in Kaliningrad and their radars.

Third, placing nuclear weapons in Poland would be hugely provocative to Russia. This is not an argument against provoking Russia in general — given its provocative behavior, including a military build-up, bellicose rhetoric, and use of military force against Ukraine. (Indeed, I called in 2014 for Washington to provide lethal military assistance to Ukraine and for U.S. and NATO forces to deploy to the Baltic states, steps that Moscow deemed “provocative.”)

But there is provocative and there is provocative. Putting U.S. nuclear arms so close to Russia would be the latter. Recall the 1962 Cuban Missile Crisis, when the Soviet Union placed nuclear weapons 90 miles from American shores. President John F. Kennedy imposed a naval blockade, which allowed time to work out a settlement with Moscow. In doing so, however, he set aside the recommendation of many of his advisers for air strikes and a full-scale invasion of Cuba.

Fourth, a U.S. proposal to relocate its nuclear weapons to Poland would prove very divisive within NATO. The members of the alliance stated in 1997 that “they have no intention, no plan, and no reason to deploy nuclear weapons on the territory of new [NATO] members.” They incorporated that into the “Founding Act” that established relations between NATO and Russia.

The security circumstances in Europe have changed dramatically and, unfortunately, for the worse over the past 23 years. Despite that, many NATO members still support the “three no’s” regarding nuclear weapons that the alliance adopted in 1997. A U.S. proposal to move the bombs to Poland would divide allies, cause some to question U.S. judgment, and prompt a broader nuclear debate within the alliance at a time when NATO should strive to show a firm and united stance toward Russia.

Relocating U.S. nuclear weapons to Poland would be expensive, militarily unwise because it would make the weapons more vulnerable to preemptive attack, unduly provocative, and divisive within NATO. This was a tweet best not sent. The one thing it does do, however, is give Mr. Mützenich a new talking point for removing the bombs from Germany; citing Ambassador Mosbacher, he can claim: “We can send them to Poland.”

In my line of work, you have to have a long memory. Periods of success in negotiations are followed by droughts, because of politics, military upheaval, arms buildups—yes, sometimes the weapons have to be built before they can be reduced—or a sense of complacency: “We have arms control treaties in place; let’s just focus on implementing them.” In those cases, new thinking and new negotiations may slow or even stop. Yet, the national security interest of the United States continues to drive the necessity for nuclear arms control.

Former Russian President Dmitry Medvedev, who signed the New Strategic Arms Reduction Treaty (New START) with Barack Obama on April 8, 2010, called last week for the United States to agree to extend the treaty. On Friday, a Department of State spokesperson told the Russian news agency TASS in response:  “The President has directed us to think more broadly than New START…  We stand ready to engage with both Russia and China on arms control negotiations that meet our criteria.”

Unfortunately, nothing suggests President Trump will achieve anything on nuclear arms control.
