Editor’s note: This article is part of an ongoing WPR series inviting authors to identify the biggest priority—whether a threat, risk, opportunity or challenge—facing the international order and U.S. foreign policy today. Just 25 years after winning the Cold War, with the collapse of the Soviet Union and the communist regimes of Eastern Europe, the United States is facing a very different world than the one many had expected. Instead of a world of relative peace, with no proxy wars in developing countries and no major global geostrategic opponents, there is violence and terrorism around the globe, much of it […]

Colombian President Juan Manuel Santos gives Senate President Mauricio Lizcano the peace deal with FARC rebels, Bogota, Colombia, Aug. 25, 2016 (AP photo by Felipe Caicedo).

Here is a moral dilemma: Would you be happy to live in a world in which 80 percent of the population enjoys more or less peaceful conditions, but the remaining 20 percent are condemned to live with a worsening spiral of war and suffering? This is a useful question, because it is a rough description of the actual world we live in. Most of the planet is pretty stable these days. Last week, the cognitive scientist Stephen Pinker and Colombian President Juan Manuel Santos underscored this point in an opinion piece celebrating Colombia’s peace deal with the leftist Revolutionary Armed […]

U.N. Secretary-General Ban Ki-moon greets Hillary Clinton at a U.N. Women event, U.N. headquarters, March 7, 2014 (U.N. photo by JC McIlwaine).

If Hillary Clinton is elected president of the United States in November, fixing the failings of United Nations peacekeeping operations is unlikely to be one of her foreign policy priorities. Putting Russia in its place and balancing China in the Pacific will loom much larger on her to-do list. But the next administration is likely to find that crises involving blue helmets have a habit of creeping up its agenda. Clinton is presumably painfully aware of this. Her husband’s presidency was punctuated by peacekeeping failures from Somalia to Srebrenica, and the failure to give U.N. personnel effective back-up during the […]

Editor’s note: This article is part of an ongoing WPR series inviting authors to identify the biggest priority—whether a threat, risk, opportunity or challenge—facing the international order and U.S. foreign policy today. For the prosperous and stable nations of Europe and North America, the cost of terrorism is usually dwarfed by the cost of reactions to it. Avoiding such overreaction is the most pressing challenge in security policy today. The number of Westerners killed by terrorists has grown of late, thanks largely to attacks in Brussels, Paris, Istanbul and Nice related to the self-described Islamic State. Still, the threat remains […]

So far, the Olympic Games in Rio are off to a good start. No major disasters have occurred, despite serious worries about security and environmental conditions. But the games—and particularly the downsides like excessive costs, corruption and imbalances of power and influence—have raised questions of politics and economics that bear many similarities to some of the major trends in international affairs. One innovative proposal for fixing the Olympics provides a useful comparison to some notions of how to improve the global governance system. Hosting the Olympics has already been costly for Brazil—in financial terms for sure, at $12 billion, of […]

Republican presidential nominee Donald Trump has punctuated his campaign with foolish and frankly dangerous comments on foreign affairs. He has made recurrent gaffes about nuclear weapons and U.S. alliances. But just occasionally he says something almost sensible. Last month, a journalist asked Trump how he would persuade Turkey to focus on fighting the so-called Islamic State rather than armed Kurdish groups in the country’s southeastern region. “Meetings,” he replied. “If I ever have the opportunity to do it, meaning if we win, we will have meetings, we will have meetings very early on.” Foreign policy experts wrote this off as […]

Climate-driven migration will likely affect millions of people in the coming decades, adding to the displacement of millions from war and instability. States and international organizations will need to dedicate additional resources to climate migrants, but they can already begin by integrating support into essential resilience and adaptation responses currently underway. Climate change policies are beginning to confront the complex dynamics of populations living in areas that are no longer habitable due to sea-level rise, desertification or other effects. Politics and policy choices are starting to play out at various levels. And the migrants themselves are grappling with decisions at […]

Peacekeepers and U.N. police officers conduct a search for weapons and contraband, Juba, South Sudan, July 19, 2016 (U.N. photo by Eric Kanalstein).

The United Nations is constantly embroiled in brutal conflicts, but some do it vastly more political harm than others. The organization has never fully recovered from its failure to prevent the Rwandan genocide and Srebrenica massacre in the 1990s. Now it faces simultaneous crises in South Sudan and Syria that may do it equally severe damage. In South Sudan, peacekeepers have been thrown off balance by an outburst of violence for the second time in three years. The U.N. mission (UNMISS) there was unable to stop the country collapsing into civil war in 2013, but managed to protect tens of […]
