Policy Briefs & Testimonies

This policy brief is based on "Should the United States Reject MAD? Damage Limitation and U.S. Nuclear Strategy toward China" which will appear in the summer 2016 issue of International Security.

Information technology has generated tremendous wealth and innovation for millions, underwriting the United States' preponderance as well as China's meteoric rise. The costs of cyber espionage and harassment pale beside the mutual benefits of an interdependent, globalized economy. The inevitable frictions of cyberspace are not a harbinger of catastrophe to come, but rather a sign that the states inflicting them lack incentives to cause any real harm. Exaggerated fears of cyberwarfare or an erosion of the United States' competitive advantage must not be allowed to undermine the institutions and architectures that make the digital commons so productive.

"...[A]ssessing the bioterrorism threat coming from the life sciences requires a broad range of expertise and information. A better analysis of such threats would involve relevant analysts within the intelligence community engaging with a range of social science experts. Such experts could provide information about terrorist intentions, motivations, and capabilities, as well as a more nuanced understanding of the difficulties involved in replicating scientific experiments and utilizing them for terrorist purposes."

Why did violence decline in Iraq in 2007? Many credit the "surge," or the program of U.S. reinforcements and doctrinal changes that began in January 2007. Others cite the voluntary insurgent stand-downs of the Sunni Awakening or say that the violence had simply run its course after a wave of sectarian cleansing. Evidence drawn from recently declassified data on violence at local levels and a series of seventy structured interviews with coalition participants finds little support for the cleansing or Awakening theses. This analysis constitutes the first attempt to gather systematic evidence across space and time to help resolve this debate, and it shows that a synergistic interaction between the surge and the Awakening was required for violence to drop as quickly and widely as it did.

Why do terrorist attacks frequently succeed, even though later investigations almost always show that warnings had been available but were either misunderstood or ignored?  Conventional wisdom, as seen in the 9/11 Commission Report, holds that disasters such as the 9/11 attacks have been caused by failures of analytical imagination, a lack of long-term strategic intelligence on the threat, and organizational limitations that prevent the U.S. intelligence community from being able to “connect the dots” of the existing intelligence.
