Jay Mens asks: Why won't the U.S. admit that Iran's proxies, which include Hamas, are acting in concert?

Plastic pollution in the Arctic marine system is sparsely quantified, and few enforceable policies are in place to ameliorate the issue. In this paper, Dewey and Mackie estimate the flux of plastic through rivers, sea ice, and ocean, and quantify marine plastic pollution from Arctic shipping and fishing. They also examine how a suite of proposed policy interventions would quantitatively change those concentrations.

Former International Security Program Research Fellow Rebecca Weiner is profiled by the New York Times after becoming the New York Police Department's deputy commissioner of intelligence and counterterrorism. The former deputy commissioner of the bureau, John Miller, in 2014, said she had a "remarkable" ability to recognize how security threats were changing.

Calder Walton recounts how Russia and China are using their intelligence agencies to reverse the outcome of the Cold War

Divestment is a prominent strategy championed by activists to induce positive social change. For example, the current fossil fuel divestment movement includes over 1,500 institutions that control $40 trillion in assets. A primary pathway through which divestment is theorized to be effective is by influencing public beliefs and policy preferences, thus pressuring policymakers to take action. However, prior research only tests this argument via qualitative case studies. The authors assess the impact of exposure to information about fossil fuel divestment on public opinion through the use of national survey experiments in three major greenhouse gas emitters: the U.S., India, and South Africa.

This paper explores the unique conditions that made the Agreement to Prevent Unregulated High Seas Fisheries in the Central Arctic Ocean possible and examines how success was achieved by the interrelationships of science, policy, legal structures, politics, stakeholder collaboration, and diplomacy.

Do armed drone programs decrease or increase terrorism? Existing studies on this question produce conflicting arguments and evidence. Drone optimists contend that armed drones reduce a country's vulnerability to terrorism, while pessimists claim that this military technology provokes higher levels of terrorism. Prior research focuses almost exclusively on one particular context: the short-term effect of the US drone program in Pakistan. However, armed drones have proliferated rapidly over the last decade and eighteen countries now possess this technology. The authors expand the scope of prior studies by leveraging new data to assess how obtaining armed drones and conducting drone strikes changed the degree to which all drone possessors experienced terrorism between 2001 and 2019.

A new theory of war duration suggests that strategic narratives explain why the U.S. war in Afghanistan endured and ended. A robust anti-terrorism narrative generated audience costs for presidential inaction. As the narrative weakened, these costs declined, and the war ended.

The costly Ground-based Midcourse Defense system remains unproven and unreliable in deterring North Korea’s threat to use intercontinental ballistic missiles. An airborne boost-phase intercept system may offer an alternative defense against North Korea without threatening Russian or Chinese deterrents.

White Southerners opposed to Reconstruction used violence to undermine Black political power and force uncommitted white Southerners to their side. Although structural factors made it harder for the U.S. government to suppress this violence, a series of policy failures prompted Reconstruction’s failure and generations of injustice.
