On March 30, President Barack Obama hosted the fourth and final Nuclear Security Summit, where global leaders convene in an effort to secure nuclear materials and prevent nuclear terrorism. Along with Obama’s vision articulated in a 2009 speech in Prague of a world without nuclear weapons, the summits provide an important marker for assessing Obama’s record on reducing the security risks posed by nuclear weapons and material.

The conflict over Western Sahara has lasted well over 40 years—25 under the oversight of the United Nations Security Council since it brokered a cease-fire in 1991—but it suffered the latest and perhaps worst of its many setbacks earlier this month, thanks to none other than U.N. Secretary-General Ban Ki-moon. Ban caused an uproar in Morocco by calling its presence in Western Sahara an “occupation,” while he was visiting a refugee camp in Tindouf, Algeria, near the border with the disputed territory. Ban’s comments came during a larger visit to North Africa that did not include Morocco, the key player […]

The cynical deal struck between the European Union and Turkey aimed at stemming the flow of refugees into Europe is a sign of desperation. It is flawed on several levels, and is likely to do harm to Europe’s image as a champion of international norms and Western values. Ironically, it will also probably do more harm than good to any hopes Turkey may still harbor for EU membership. But for all its shortcomings, the deal is better than doing nothing, and its effective implementation will help restore Europe’s self-confidence and Turkey’s role as a regional problem-solver. The deal finalized Friday […]

The use of unmanned aerial vehicles for lethal purposes has generated passionate debates about how this not-so-new technology has changed the rules of war, creating a demand for new global norms. On the domestic front, drone technology raises difficult public policy issues related to commerce, ethics, air safety and good government. The Obama administration’s recent decision to release its policy guidance for drone use will help temper public misgivings, but the debate will continue. Last week, the Obama administration indicated that it will release the policy guidance used by U.S. national security agencies for use of unmanned aerial vehicles in […]

The past year has seen the emergence of the biggest refugee crisis in Europe since the end of World War II, with almost 1.3 million asylum-seekers arriving in 2015, mostly on boats from Turkey or North Africa. The vast majority have been Syrians fleeing the devastating collapse of their country, though they have been joined by people from Iraq, Afghanistan, Eritrea and a range of other troubled countries. Those seeking protection have arrived in a divided, disorganized and panicked continent. The inadequacy of Europe’s response has jeopardized not only international refugee norms but, in the recent words of French Prime […]

Last week, U.S. warplanes bombed the Libyan town of Sabratha, targeting militants of the self-declared Islamic State. The move is the most recent illustration of the dilemma presented by Libya’s political and security stalemate, characterized by political infighting and militia violence. The Islamic State’s emergence in the country in early 2015 has given the situation regional implications. The United States is weighing its next steps, amid ongoing questions about its role in the 2011 NATO intervention that some see as the source of today’s chaos.
