Antisemitic incidents reached an all-time high in the United States in 2021, with a total of 2,717 incidents of assault, harassment and vandalism. This represents the highest number of incidents on record since 1979 – an average of more than seven incidents per day and a 34 percent increase year over year. Incidents reported in all 50 states. Attacks against synagogues and JCCs increased 61 percent.

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.”

Islamist extremists online are taking note of three new English language publications—two linked to Al Qaeda and one from ISIS. All three magazines are positioned to fill the void left by the dissolution of Al Qaeda’s notorious Inspire magazine. 

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.”

Farmers are adopting precision agriculture, using data collected by GPS, satellite imagery, internet-connected sensors and other technologies to farm more efficiently. These practices could help increase crop yields and reduce costs, but the technology behind the practices is creating opportunities for extremists, terrorists and adversarial governments to attack farming machinery, with the aim of disrupting food production.

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-Zawahiri leaves behind a robust network of strategically aligned but tactically independent al-Qaeda affiliates operating in Africa, Asia, and the Middle East.

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.

Political and religious extremism has long been seen as a threat to democracy in Germany. The Counter Terrorism Center is where agencies and police network to prevent Islamist extremist attacks. Is it effective?
