U.S. Secretary of Defense Chuck Hagel apparently drew the short straw and emerged as the first sacrificial victim dispatched by President Barack Obama in response to his party’s dismal midterm election results, which will cost the Democrats control of the Senate. Beyond that, however, it is clear that the focus of U.S. national security has shifted dramatically over the past two years. Hagel was selected to preside over the American disengagement from the Middle East, to usher through a series of lean budgetary years for the Pentagon and to lay the foundations for the eventual rebalance of American strategic priorities […]

This week, military planners from more than 30 countries are gathered at MacDill Air Force Base in Tampa, Florida, to plot their approach against the so-called Islamic State (IS). On the other side of the world, IS is probably mulling its strategy as well. It is easy to imagine how different the two sessions must be, yet the two groups do have one thing in common: Both know that if their strategies are to work, they must first try to get inside the mind of their enemy. Anticipating what the enemy will do—what security experts call “red teaming”—is never easy, […]

U.S. Secretary of State John Kerry addresses reporters after meeting with French Foreign Minister Laurent Fabius in Paris, France, Nov. 20, 2014 (State Department photo).

U.S. Secretary of State John Kerry’s last-minute whirlwind tour of European capitals in the run-up to the Nov. 24 deadline for reaching a nuclear deal with Iran calls to mind the old aphorism about diplomacy: The hardest part isn’t getting the other side to agree to the deal, it’s convincing your own side to agree to it. In this case, Kerry’s stopover today in Paris for talks with French Foreign Minister Laurent Fabius is illustrative. In November 2013, Fabius played a high-profile—and high-stakes—role in toughening up the initial interim framework accord that was extended once already and is now set […]

When the European Space Agency (ESA) successfully landed the spacecraft Philae on a comet last week, it accomplished something once thought to be the sole purview of the superpowers. In truth, the ESA—a consortium of 20 formal members—highlights a well-established and accelerating trend: Whereas space was once beyond the reach of all but the United States and the Soviet Union, recent decades have witnessed the spread and maturing capabilities of new space powers around the world. While the United States has reasons to be concerned with that shift related to national security, it also has cause to celebrate, as promoting […]

U.S. Secretary of Defense Chuck Hagel recently announced a pair of important initiatives, one to restore the Defense Department’s troubled nuclear enterprise to health and another to spur innovation within the department. The two initiatives are necessary, if incomplete, but achieving both goals will difficult. Hagel’s proposed overhaul of the Defense Department’s management of its nuclear weapons enterprise is long overdue. The U.S. nuclear command’s core components, besides the actual warheads, include the Air Force’s nuclear-capable bombers and intercontinental ballistic missiles (ICBMs) and the Navy’s ballistic missile submarines as well as the supporting infrastructure for the entire system. It also […]

U.S. President Barack Obama shakes hands with Myanmar President Thein Sein, Naypyitaw, Myanmar, Nov. 13, 2014 (AP photo by Gemunu Amarasinghe).

Yesterday, U.S. President Barack Obama arrived in Myanmar, where he will attend the East Asia Summit and the U.S.-Association of Southeast Asian Nations (ASEAN) summit as well as meet with national leaders. The visit comes less than two years after Obama’s first to the Southeast Asian nation, which was also the first ever by a sitting U.S. president. Obama’s 2012 Myanmar trip was “a symbolic visit to reinforce the message that reform needs to be consolidated. It is a mark of appreciation, a reward if you like, and at the same time it is a measure to press for further […]

Inside the United States, supporters of President Barack Obama have all sorts of explanations for the defeat handed the Democratic Party in last week’s midterm elections, which not only increased the Republican majority in the House of Representatives but also gave the GOP control of the Senate. Democrats’ failure to mobilize their traditional voters to turn out at the polls; accusations of voter-suppression techniques, which disproportionally impact those more likely to cast ballots for the Democratic Party; and the Republicans’ successful efforts at playing up anxieties about the economy, Ebola and the so-called Islamic State (IS) have all been put […]

U.S. Secretary of State John Kerry talks with Russian Foreign Minister Sergey Lavrov before the start of the NATO-Russia Council at NATO headquarters in Brussels, Dec. 4, 2013 (AP photo by Pablo Martinez Monsivais, Pool).

To what extent is the crisis in Ukraine the result, and not the cause, of a dysfunctional relationship between Russia and the West? This question was posed for discussion this past week at a task force convened in Sofia, Bulgaria, by the Nuclear Threat Initiative, the European Leadership Network and the Russian International Affairs Council, among others, to discuss Ukraine and the future of Euro-Atlantic security. Certainly, some aspects of the disagreements between Russia and Ukraine are sui generis. Yet the core of the dispute is rooted, on one hand, in the desire of many Ukrainians to break out of […]

Russian Foreign Minister Sergey Lavrov addresses the media at the Nuclear Security Summit (NSS) in The Hague, Netherlands, March 24, 2014 (AP photo by Yves Logghe).

Russia’s decision to skip the first planning meeting for the 2016 Nuclear Security Summit (NSS) is an alarming sign that U.S.-Russia tensions over Ukraine and other issues may disrupt their nuclear security partnership. At best, the Russian decision may simply reflect an attempt to signal irritation at the U.S. by disrupting one of Washington’s highest priorities, that of countering nuclear terrorism. At worst, it may represent a decision to boycott the entire NSS process simply because the United States is hosting it. In either case, the Russian decision is extremely counterproductive. In the short term, it risks sabotaging the tacit […]
