| June 12, 2023

Technology companies and governments have spent the past decade trying to better address the evolving threat of terrorist and violent extremist content online (TVEC). This paper examines how effective these efforts have been, where we are today in managing the problem, and wherein lie gaps for improvement.

The ecological tradeoffs of desalination in land-constrained countries seeking to mitigate climate change

| Feb. 18, 2022

The global demand for desalinated water is increasing at a remarkable rate. In a future with increasing demand for water and low-carbon electricity, an interesting ecological dilemma emerges. In a decarbonized world, providing desalinated water for domestic use and aquatic ecological restoration could increasingly come at the expense of open space lost to renewables such as solar photovoltaics (PV) and wind turbines. In this article we examine the environmental tradeoffs of providing freshwater from desalination under a solar photovoltaic-based decarbonization strategy, using Israel as an example.

America's New Great-Power Strategy

| Aug. 03, 2021

During the Cold War, US grand strategy focused on containing the power of the Soviet Union. China's rise now requires America and its allies to develop a strategy that seeks not total victory over an existential threat, but rather managed competition that allows for both cooperation and rivalry within a rules-based system.

Avoiding a Plastic Pandemic: The Future of Sustainability in a Post COVID-19 World

| January 2021

The ongoing COVID-19 pandemic is upending our lives and the global economy in ways unimaginable until recently. While the overall impacts are still difficult to quantify, ramifications are sure to be felt for decades to come. Providing secure, reliable, and affordable resources for all without causing devastating environmental consequences is perhaps the greatest challenge of the 21st century. But the pandemic has significantly altered dynamics and changed priorities. How is this impacting the quest for sustainability?

In this paper we analyze these challenges by focusing on the plastic industry. There is no doubt that plastic has molded society in many ways that make our lives easier and safer, but it has also created a global environmental and sustainability crisis. In order to curb our addiction to plastic, the world had been waging a war against virgin plastic, but the pandemic has turned an enemy into a much-needed ally. How can we leverage the advantages of plastic without contributing to the world’s environmental crisis? This dilemma poses a significant challenge, but also opens an opportunity to address sustainability at a systemic level through circularity and the transition to low-carbon alternatives to petroleum-based plastics.

How MAGA Extremism Ends

| Jan. 12, 2021

Juliette Kayyem argues that if Trump keeps losing, the risk of future violence will abate. Keeping Trump in office until January 20 won't assuage the supporters who falsely believe that the election was stolen from him, but removing him from office a week early would emphasize that he is losing. Recruitment is easier for a winning team.
