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?

As Russian attacks on civilian sites are reported on a near-daily basis, pressure is mounting on the Biden administration to officially designate Russia as a state sponsor of terrorism.

“The threat from Extreme Right-Wing Terrorism is on an upward trajectory, populated by an increasing number of young people and driven by the internet,” said Julian Lewis, MP, the chairman of the U.K. Parliament Intelligence and Security Committee. The committee has just released a detailed report on the threat of terrorism in the United Kingdom.

Early in the Biden administration, the president instructed the intelligence community to evaluate the domestic terrorist threat – and intelligence officials concluded that it’s severe. On 15 June 2021, the Biden administration released the National Strategy to Counter Domestic Terrorism. Ryan B. Greer writes that now that it has been a full year since the launch, there is an opportunity to review the administration’s progress made toward countering the threat of domestic violent extremism.
