Not Just The Caliphate: Non-Islamic State-Related Jihadist Terrorism in America
Authored by Sarah Gilkes
December 2016

While there has been a relative surge in the number of U.S. persons radicalized and recruited by the Islamic State in the last five years, other jihadist organizations, primarily al-Qaeda, remain popular and active. This suggests that, while group affiliation matters, the draw of the wider Salafi-jihadist ideology that al-Qaeda, IS, and other like-minded groups adhere to is equally important when analyzing the jihadist threat to America.

November 2016

The self-proclaimed Islamic State and other jihadist actors have identified several unique roles for Western women in their radicalization and recruitment efforts. This report finds that, while few conduct violent plots, many disseminate propaganda, donate resources, or travel abroad to offer their support. This report uses a wealth of primary and secondary data to examine the efforts of 25 jihadi women in America from January 2011 to September 2016.

ISIS in America: From Retweets to Raqqa
Authored by Lorenzo Vidino and Seamus Hughes
December 2015

Our report consists of two parts. The first examines all cases of U.S. persons arrested, indicted, or convicted in the United States for Islamic State-related activities. A wide array of legal documents related to these cases provides empirical evidence for identifying several demographic factors related to the arrested individuals. This section also looks at the cases of other Americans who, while not in the legal system, are known to have engaged in IS-inspired behavior.

The second part of the report examines various aspects of the IS-related mobilization in America. Here the report analyzes the individual motivations of IS supporters; the role of the Internet and, in particular, social media, in their radicalization and recruitment processes; whether their radicalization took place in isolation or with other, like-minded individuals; and the degree of their tangible links to IS.  It concludes with recommendations to combat IS recruitment.

American and European Foreign Fighters: Assessing and Comparing the Threat

The panelists engaged in a lengthy examination of the threat of FTFs, while comparing and contrasting threats and government responses in the US and Europe.

Countering Violent Extremism (CVE) in America is our launch report. First, it analyzes the status quo of CVE in the United States, detailing the latest initiatives and the challenges. Second, it summarizes the current CVE trends in various European countries, where authorities have implemented ambitious strategies for over a decade, and whose experience can therefore offer useful pointers to U.S. officials. Finally, the report seeks to provide recommendations such as advocating for targeted interventions.
