One of the more notable storylines throughout 2014 was the continued failures of the U.S. Secret Service. There were three striking high profile lapses in the Secret Service’s ability to protect President Obama: one where a man jumped over the White House fence, running through the front door of the White House and throughout its main floor; another where an armed man with an arrest record was able to ride on the same elevator as the President; and another where a man posing as a Member of Congress was able  to sneak into a secured area where the President was speaking. Towards the end of the year, problems within the Secret Service became a hotly debated political football, resulting in the resignation of the Service’s director.

Last week, the House and Senate agreed on a budget to fund the federal government—including nonproliferation and nuclear security programs—through fiscal year 2015. Despite its participation in the Nuclear Security Summit earlier in 2014 and strong rhetoric from President Obama about the need to prioritize nuclear security, his administration proposed cutting spending on programs to strengthen security for nuclear weapons useable material for the third year in a row. In response, twenty-six Senators signed a letter to the Obama administration requesting that funding for nonproliferation and nuclear security programs be increased.

Advocates of preventing nuclear terrorism received an early holiday present. Earlier in the year, two of the four Congressional committees most directly responsible for nuclear security policy had included language in bills that would have damaged the United States' ability to engage in nuclear security cooperation with Russia.  But Congress has taken responsible action in supporting continued work with Russia in this area in the combined House-Senate version of the FY2015 National Defense Authorization Act.

Last week, the editor for the New York Times “Room for Debate” blog asked me to comment on the question, “Should Washington and Moscow continue to work together to reduce nuclear stockpiles and cooperate to secure, or eliminate, weapons and nuclear materials despite the dispute around Russian actions in Ukraine?”  I wrote, “We should honor our New START commitments,” but, beyond that, “until Russia removes its troops from eastern Ukraine and ceases its military support to pro-Russian separatists there, the United States should suspend any discussion on future arms reductions or cooperation on securing Russian nuclear materials and weapons.”  Four other commenters disagreed with my recommendation.

Last weekend, the New York Times published a debate on whether, as a result of tension over Ukraine, the United States should cut off nuclear security cooperation with Russia. As the Times reported before the debate, Russia may be bringing nearly all of this cooperation to an end–but there are some in the United States saying the U.S. government should act to end it whether or not Russia is willing to continue. Given the deteriorating relationship between the two countries, this issue should be debated now. We are continuing the debate on Nuclear Security Matters and welcome readers to send us their thoughts.

Yesterday, the New York Times published an article revealing that, at the end of 2014, Russia plans to reduce its cooperation with the United States on securing nuclear materials within its borders. The United States and Russia have made substantial progress in securing nuclear material over the past two decades, but more work is needed. Halting cooperation not only risks future progress on reducing the risk of nuclear terrorism, but also jeopardizes progress to date.

Matthew Bunn, Will Tobey, Hui Zhang, and Nickolas Roth recently participated in a two-day roundtable discussion sponsored by the Stanley Foundation on U.S. nuclear security cooperation with Russia and China. The discussion, which involved experts from around the world, focused on overcoming challenges to nuclear security cooperation and ensuring that countries put in place effective and sustainable nuclear security measures with strong security culture.
