On this day 75 years ago, the world entered the nuclear age. The first ever nuclear detonation – known as the Trinity test – took place in New Mexico on July 16th, 1945. Since then, ten countries built more than 134,000 nuclear weapons. More than 13,400 remain today.

In the decades that followed, nuclear testing contaminated lands, oceans, and people, and triggered a nuclear arms race that continues to this day. The Federation of American Scientists is honored to join our colleagues at the Union of Concerned Scientists and Tularosa Basin Downwinders Consortium in a joint statement with five other U.S. organizations on the humanitarian consequences of nuclear testing, endured by victims in the United States and its Pacific territories, from French nuclear testing in French Polynesia and Algeria, Russian nuclear testing in Kazakhstan, British nuclear testing in Australia, and others.

In addition to these harms, the Trinity test marked the beginning of the global nuclear arms race with its endless cycles of nuclear modernization and competition, which continue to this day. Unlike any other invention, nuclear weapons have the capability to destroy human civilization and much or life on Planet Earth.

The Federation of American Scientists has tracked the rise and fall of global nuclear arsenals for many years. Despite reductions since the Cold War, there are still more than 13,000 nuclear weapons in the world. And we are disappointed to note the emergence of five disturbing trends regarding the current and future state of nuclear weapons:

1. Every nuclear-armed country is currently in the midst of modernizing their nuclear arsenals. Some countries are actually increasing their stockpiles, while others are swapping out their older weapons with newer, more effective ones that will endure almost until the end of the 21st century.
2. Not only are nuclear arsenals either increasing or improving, but it appears that many states are reinvigorating or even expanding the role of nuclear weapons – specifically tactical nuclear weapons – in their military doctrines. State representatives have often claimed that these deployments are actually intended to prevent conflict; however, regardless of how much stake one puts into that sort of statement, it is a fact that many states are now increasingly posturing themselves for nuclear warfighting. This development will make it more difficult to reduce the role of nuclear weapons and pursue significant reductions – and certainly disarmament – in the future.
3. In recent years, we have also seen the decline – and general disinterest – in arms control writ large. Today, bilateral and multilateral arms control agreements have fallen away or are under severe stress, multilateral efforts to engage in good faith arms reductions appear to have completely stagnated, and states often seem more interested in blaming and shaming their prospective arms control partners than actually pursuing measures that would offer a modicum of transparency and predictability in an otherwise unpredictable world.
4. Rather than pursue arms control, it seems that states are more content with pursuing arms competition and even arms races. This is a result of renewed military competition and is fueled by the tremendous influence that weapons contractors and lobbyists have on government decisions; indeed, sometimes nuclear decisions seem to be driven as much – if not more – by corporate interests than by national security concerns.
5. Nuclear-armed states largely do not appear to consider nuclear disarmament to be an urgent global security, humanitarian, or environmental imperative. Instead, most states seem to consider disarmament as a type of chore mandated by the Non-Proliferation Treaty – and not one that they are seriously interested in completing in the foreseeable future. It is increasingly rare to hear any officials from nuclear weapon states express a coherent rationale for pursuing disarmament other than as a result of the obligation to do so under the Non-Proliferation Treaty. Moreover, they seem increasingly focused on shifting the disarmament responsibility onto the non-nuclear states by arguing they first must create the security conditions that will make nuclear disarmament possible.

Although the Trinity test took place 75 years ago, its destructive legacy continues to this day. And despite these harms, some politicians are even trying to return to an era of live nuclear testing. Resuming nuclear explosive testing would be taking a monumental step backward and would open the floodgates for worldwide resumption of nuclear testing and development of new nuclear weapons. Instead, on this 75th anniversary, we must look forward, try our best to reverse these worrying trends, responsibly reduce the arsenals and the role that nuclear weapons serve, and work towards a world eventually free from nuclear weapons.

The Federation of American Scientists is honored to provide the world with the best non-classified estimates of the nuclear weapons arsenals. We are grateful for the financial support from the New Land Foundation, MacArthur Foundation, Ploughshares Fund, and the Prospect Hill Foundation to do this work.

In March 2013, the Senate voted down an amendment offered by Senator Rand Paul (R-KY) to cut $700,000 from their budget that was set-aside for the National Security Working Group (NSWG). What many did not realize at the time was that this relatively small and obscure proposed cut would have eliminated one of the last traces of the bipartisan Congressional approach to debating arms control.

The NSWG first began as the Arms Control Observer Group, which helped to build support for arms control in the Senate. In recent years, there have been calls from both Democrats and Republicans to revive the Observer Group, but very little analysis of the role it played. Its history illustrates the stark contrast in the Senate’s attitude and approach to arms control issues during the mid- to late 1980s compared with the divide that exists today between the two parties.

The Arms Control Observer Group

The Arms Control Observer Group was first formed in 1985. At the time, the United States was engaged in talks with the Soviet Union on the Intermediate Nuclear Forces Treaty. To generate support for ongoing negotiations, Majority Leader Senator Bob Dole (R-KS), and Minority Leader Senator Robert Byrd (D-WV), with the endorsement of President Ronald Reagan, created the bipartisan Arms Control Observer Group. The Observer Group consisted of twelve senators, with four senators, two from each party, serving as co-chairs and created an official role for senators to join U.S. delegations as they negotiated arms control treaties. As observers, its members had two duties: to consult with and advise U.S. arms control negotiating teams, and “to monitor and report to the Senate on the progress and development of negotiations.”

During meetings with U.S. State Department negotiators, senators were able to present their views, ask questions, and even engage in candid and confidential exchanges of ideas and information. Senators were also allowed to meet with members of the Soviet delegations on an “informal” basis. The Observer Group believed that the “interplay of ideas” would assist negotiators and, if negotiations failed, the members would help their fellow senators explain the reasons why to the American public.

The Observer Group served a number of purposes. First, it was intended to supplement the activities of the Senate Foreign Relations Committee. Senator Byrd argued that the process that existed up until that point—where the Foreign Relations Committee became experts on treaties and the full Senate only began to understand the issues after the negotiation—was not functioning properly. Its creators argued, “the full Senate has focused its attention in the past only sporadically on the vital aspects of arms control negotiations, usually developing a knowledge and understanding of the issues being negotiated after the fact…the result of this fitful process has been generally unsatisfactory in recent years.” During the previous decade, the Executive Branch had failed to garner enough Senate support for several arms control initiatives: the Peaceful Nuclear Explosions Treaty of 1976, the Threshold Test Ban Treaty of 1974, and the Strategic Arms Limitation Treaty (SALT II) of 1979, none of which were ratified by the United States. Although there had been previous attempts to involve senators in arms control negotiations, the Observer group provided “more regular and systematic involvement” from the full Senate long before a vote took place.

The formation of the Observer Group publicly demonstrated the important role of arms control in national security matters. The resolution that created the group states that senators have the “obligation to become as knowledgeable as possible concerning the salient issues, which are being addressed in the context of the negotiating process. Any accord with the Soviet Union to control or reduce our strategic weapons carries considerable weight for our nation.” According to Senator Sam Nunn (D-GA), a founding member of the Observer Group, “the goal [was] to have the Senate fulfill both halves of its constitutional responsibilities, not only the consent half—that’s what we’ve been looking to primarily in the past—but also the advice half.”

Additionally, the Observer Group helped develop institutional knowledge and expertise on arms control within the Senate. The Group’s founding members stated that they believed it was necessary to become “completely conversant” in issues related to treaty negotiations and that such knowledge was “critical” to the Senate’s understanding of the issues involved. To achieve that goal, they held regular behind closed-door briefings on negotiations for senators and their staff and some staffers were able to review related classified materials.  Observer Group members were conversant in issues related to previous arms control treaties, missile defense, the connection between strategic offense and defense, and treaty compliance.

Above all, the Observer Group was intended to help build bipartisan support for President Reagan’s arms control initiatives. The group was seen as a mediating body. When it was formed, Senators Dole and Byrd co-authored a resolution stating that the Observer Group was part of “an ongoing process to reestablish a bipartisan spirit in this body’s consideration of vital national security and foreign policy issues.” Senator Richard Lugar (R-IN), who was one of the original members of the Observer Group, agreed by affirming, “The observer group is tremendously important to forming a consensus on which ratification might occur.” The Group’s 1985 report to Congress endorsed “the broad bipartisan support of the Senate for the Administration’s arms control efforts…determination to be as patient as necessary to achieve a sound agreement…the seriousness with which the Senate, including the Observer group intends to fulfill its constitutionally-mandated role in the treaty-making process.” This opinion was also shared by the Reagan administration. In a letter to Senators Dole and Byrd, Secretary of State George Shultz stated that he thought the Observer Group would help facilitate unity on arms control.

It is difficult to demonstrate the extent of its influence as the years the Observer Group was most active were also the years in which arms control was seen by both parties as a vital part of U.S. policy.  The success of these initiatives was clearly not solely due to the Observer Group, but it did play a role. Every one of the original Group’s members voted in favor of the INF Treaty in 1988, which passed 93-5.  Similarly, all of the senators within the Group voted in favor of ratifying the 1992 START Treaty, which passed 93-6.

The National Security Working Group

Towards the end of the 1990s, the Senate’s attitude towards arms control changed. Negotiations between the United States and Russia on a legally binding nuclear reduction treaty had stalled. The Senate had voted down the Comprehensive Test Ban Treaty. Reflecting this changing point of view, in 1999, Senator Trent Lott (R-MS), wanted to further diminish the Senate’s focus and expertise on arms control issues. He proposed an amendment that expanded the Observer Group’s purview to include observing talks related to missile defense and export controls and renamed it the National Security Working Group. For nearly a decade during the George W. Bush administration, which pursued relatively little in terms of legally binding arms control agreements, the NSWG was relatively dormant.

This changed in 2009 under the Obama administration when the Executive Branch started briefing senators about the ongoing New Strategic Arms Reduction Treaty (New START) negotiations. From July 6, 2009, when President Obama and Russian President Dmitry Medvedev signed an agreement to reduce American and Russian nuclear arsenals, to April 10, 2010, when they signed the negotiated treaty, the NSWG was revived in order to give senators a role in observing the negotiation process. During this ten-month period, the NSWG began meeting again. The meetings were open to members of the Armed Services and Foreign Relations committees and were well attended, with roughly 50 percent attendance from those who were invited. Senators who participated in the Working Group knew it was a serious matter and paid attention to it. As a result of their attendance, they left meetings better informed on issues related to arms control.

Throughout the course of Senate deliberation of New START, Senator Jon Kyl (R-AZ) served as the Republican Party’s key interlocutor with Democrats. Unlike his predecessors in the Observer Group, Senator Kyl did not see the Working Group as a vehicle for bipartisan cooperation and consensus building. Senator Kyl used his position as the chief negotiator to disrupt the Obama administration’s legislative agenda on arms control.

Senator Kyl used issues peripheral to the treaty, such as missile defense and modernization of the nuclear stockpile, to “slow roll” the legislative process and prevent the administration from pursuing the Comprehensive Test Ban Treaty, which he ardently opposed.¹ According to one account, Senator Kyl “was not using the Working Group. It was just a tool to stop the policy. There wasn’t a getting to yes option. It wasn’t there to get to yes. If the members of the group aren’t inclined to get to yes, then the mechanism won’t get them there.”  Further, he “came prepared to ask tough questions, not just to listen and probe. He was there to look for chinks in the arms and attack in front of his colleagues. He wanted his colleagues to see it.”

In an effort to prevent Senator Kyl from disrupting meetings, Senate staff made the NSWG open to all members of the Senate Foreign Relations and Armed Services Committees. They also made sure that senior Democratic leadership was present for all of the NSWG meetings. Either Senator John Kerry (D-MA) or Carl Levin (D-MI) served as Chair and were both prepared to answer all questions and concerns.

Despite this impediment, senators still appear to have found the Working Group useful. Senator Levin, Chairman of the Senate Armed Services Committee, said the NSWG provided an opportunity to bring senators in at the beginning of the negotiation process, and “through the group” there were “many opportunities to learn of the progress and details of negotiations and to provide our advice and views to the administration throughout the process.” He praised the NSWG’s work, arguing that it was a “key” part of the treaty ratification process because it allowed senators to begin meeting with the administration “early in the process of negotiation” before New START was finalized. He said that during the New START process, “members of the National Security Working Group asked a great number of questions, received answers at a number of meetings, stayed abreast of the negotiation details, and provided advice to the administration.” Finally, he added that, through the NSWG, the administration had the opportunity to respond to senators’ questions and concerns, which helped to avoid problems during the Senate’s consideration of the treaty.

The Senate was less supportive of arms control this time around. Even with senators actively involved in the NSWG, only 13 Republicans ended up supporting the treaty. Of those 13, only four Republicans were members of the Working Group (Senators Lugar, Corker, Voinovich, and Cochran). Among those four, only Senator Lugar was a particularly strong advocate for the treaty.

At best, the Working Group had a mixed track record and certainly did not have the same kind of success as the Observer Group. Only two senators traveled to observe New START negotiations. There was no spirit of cooperation or strong bipartisan support for the treaty. The Working Group essentially became a courtroom where New START could be prosecuted.

The Future of the NSWG

Since the vote on New START, the NSWG has not been any more successful in helping to foster bipartisanship. At the beginning of the 113^th session of Congress, Senator Dianne Feinstein (D-CA) and Senator Marco Rubio (R-FL) were appointed co-chairs.  Senator Rubio, like Senator Kyl, has attempted to impede the Obama Administration’s work on arms control.

While the cooperative atmosphere that surrounded the Arms Control Observer Group seems like an anachronism in today’s political climate, this is not meant to argue that senators within the Working Group need to agree on everything. There were major disagreements over nuclear policy during the Reagan administration and at times, heated discussions within the Observer Group. The difference was that the Observer Group was effective because the senators who were in it believed that arms control could advance U.S. national interests and wanted the group to succeed.

Today, the NSWG suffers from three broader trends within the United States that inhibit this attitude. The first is that the partisanship that exists in the Working Group is a reflection of the divisions in Congress. Given this dynamic, if there is any chance for the NSWG to serve as a valuable forum, individuals looking for the spotlight cannot be given the opportunity to hijack it. Secondly, since the end of the Cold War, detailed, negotiated arms control agreements are decreasingly seen as important to advancing U.S. national interests. There is diminishing prestige or interest in being a member of the NSWG or in supporting arms control. Thirdly, the Republican Party is far more skeptical about any legally binding international commitments than it once was.

These trends are unfortunate. The fact is that arms control still has a role to play in advancing U.S. interests and promoting international peace and stability. There are numerous issues that the United States and Russia will still need to address together. They continue to cooperate on issues related to Iran and reducing the risk of nuclear terrorism. They will likely still continue to communicate about issues related to U.S. missile defense deployment. Some think that current problems between the United States and Russia are evidence that this is not the case, but it was this kind of tension that led both countries to arms control in the first place. For this reason, diplomacy will remain an important policy tool for preventing catastrophic war between the two countries.

With diminishing nuclear policy expertise in a divided Senate, there is a need for a group of engaged, knowledgeable senators invested in arms control. For this reason, the NSWG will continue to have the opportunity to play a constructive role in informing the Senate on these issues and allowing senators into the diplomatic process.

The first members of the Group were Senator Ted Stevens (R-Alaska), Sam Nunn (D-Georgia), Richard Lugar (R-Indiana), Claiborne Pell (D-Rhode Island), Al Gore (D-Tennessee), Ted Kennedy (D-Massachusetts), Pat Moynihan (D-New York), Don Nickles (R-Oklahoma), John Warner (R-Virginia), and Malcolm Wallop (R-Wyoming).

On May 20-21, 28 NATO member countries will convene in Chicago to approve the conclusions of a year-long Deterrence and Defense Posture Review (DDPR). Among other issues, the review will determine the number and role of the U.S. non-strategic nuclear weapons deployed in Europe and how NATO might work to reduce its nuclear posture as well as Russia’s inventory of such weapons in the future.

Lack of transparency fuels mistrust and worst-case assumptions and the concerns some eastern NATO countries have about Russia have been used to prevent a withdrawal of the remaining U.S. nuclear weapons from Europe. The DDPR is expected to endorse the current deployment in Europe.

A new FAS report (PDF) concludes that non-strategic nuclear weapons are neither the reason nor the solution for Europe’s security issues today but that lack of political leadership has allowed bureaucrats to give these weapons a legitimacy they don’t possess and shouldn’t have.

The Nuclear Non-Proliferation Treaty (NPT) has endured as the cornerstone of the non-proliferation regime and remains the only legally binding multilateral agreement on nuclear disarmament. In May 2010, the NPT Review Conference met at the United Nations and provided a critical opportunity to advance the vision President Obama laid out of a world free of nuclear weapons.
