  • Five Years After “Unite the Right”: Reflections on Charlottesville for Today’s Threat Landscape

    Five years ago, racially or ethnically motivated violent extremists from across the United States traveled to Charlottesville, Virginia for the “Unite the Right” rally. Nicholas Rasmussen and Sarah Kenny write that “Unite the Right” is best appreciated as a watershed moment in U.S. politics. “With the clear vision of hindsight, the incidents in Charlottesville five years ago sounded a wakeup call about where the United States may be headed.” The very real threat “of political violence and radicalization that flow from the highly toxic political climate we currently live in, make for a turbulent domestic threat landscape in both city parks and virtual chatrooms.”

  • Mar-a-Lago Search Sparks Antisemitic Conspiracy Theories Online

    Antisemitic conspiracy theories circulated widely on social media after the search at Mar-a-Lago.

  • A Century-and-a-Half Look at the Waves of Global Terrorism

    Twenty years ago, a 15-page article – “The Four Waves of Rebel Terrorism and September 11” — by terrorism expert David Rapoport helped students of terrorism place the 9/11 attacks in perspective. Rapoport has now published a 440-page book on the topic, and Tim Wilson writes that “[Rapoport’s] provocative sketch of how global terrorism emerged has continued to hold the field since the immediate aftermath of 9/11. And this new volume allows him to present it in fuller, and richer, brush-strokes.”

  • Rise of Precision Agriculture Exposes Food System to New Threats

    Farmers are adopting precision agriculture, using data collected by GPS, satellite imagery, internet-connected sensors and other technologies to farm more efficiently.

  • FBI: Al-Qaida Determined to Strike at US Despite Leader's Killing

    The FBI remains worried about the potential for a large-scale attack planned or inspired by al-Qaida despite the killing of its top leader in a U.S. drone strike in Afghanistan last weekend. Ayman Al-Zawahiri, who took over as al-Qaida leader after Osama bin Laden was killed in a U.S. raid in 2011, was on the FBI’s Most Wanted List with a $25 million reward for his capture.

  • Ayman al-Zawahri’s Killing, Kits Impact on al-Qaida, and U.S. Counterterrorism?

    The American withdrawal from Afghanistan in August 2021 prompted questions over whether the U.S. could keep pressure on al-Qaida, ISIS-K and other militants in the country. U.S. officials explained that an “over-the-horizon” strategy would allow the U.S. to deal with problems that emerged, but many experts disagreed. The debate over capabilities continues, but for those who doubted whether the U.S. still had the desire to go after key terrorists in Afghanistan, the killing of al-Zawahri gives a clear answer.

  • There Is a Lot of Antisemitic Hate Speech on Social Media – and Algorithms Are Partly to Blame

    Antisemitic incidents have shown a sharp rise in the United States. There were 2,717 incidents in 2021. This represents an increase of 34% over 2020. In Europe, the European Commission found a sevenfold increase in antisemitic postings across French language accounts, and an over thirteenfold increase in antisemitic comments within German channels during the pandemic. Contemporary antisemitism manifests itself in various forms such as GIFs, memes, vlogs, comments and reactions such as likes and dislikes on the platforms. The continuous exposure to antisemitic content at a young age, scholars say, can lead to both normalization of the content and radicalization of the Tik-Tok viewer.
