As the investigation of the killing of pro-immigration politician Walter Lübcke intensifies, Cologne’s mayor and several other German politicians who support generous refugee admission policies have had their lives threatened. Two of these politicians, in 2017, have already been attacked by knife-wielding far-right extremists.

On June 2, Walter Lübcke was found dead in his garden with a bullet wound in the head. In his home town of Kassel, in the heart of Germany, the affable 65-year-old politician was a well-known member of Chancellor Angela Merkel’s center right party who had welcomed immigrants when she opened the country’s doors to refugees in 2015—and who had weathered a storm of hatred on social media as a result. Josephine Huetlin writes in the Daily Beast that at first, police insisted there was no political connection to the murder, and several investigators dismissed the possibility the killer came from the far right. But this week they arrested a suspect with neo-Nazi associations and a history of racist crimes. Now, the federal prosecutor’s office has taken over the case, which means it will be treated as an act of extremism and, in effect, of terrorism.

Scanning the brains of men who support a terror organization associated with Al Qaeda reveals insights into the psychology of radicalization and terrorist violence. Arguments and attempts at persuasion that rely on rational and seemingly reasonable attempts to pull people away also will have limited impact because the part of their brain associated with deliberative reasoning has deactivated.

While white supremacists and other right-wing extremists are responsible for most extremist-related domestic murders committed in the past decade, terrorism and violence inspired by Islamist extremism continues to pose a serious threat to Americans. ISIS’s violent ideology continues to resonate with and radicalize U.S. citizens, but domestic Islamist extremists are increasingly seeking inspiration from other foreign terror organizations such as Al Qaeda. In 2018, 13 individuals were arrested for domestic criminal activity motivated by Islamist extremism — all of them were lawfully in the United States at the time of their arrest. The number of individuals arrested for domestic Islamist extremist criminal activity decreased from 2017 to 2018 by approximately 40 percent.

English-speaking Islamic State supporters are refusing to give up on the terror group’s ability to remain a force in Syria and Iraq. Even as the terror group was losing ground in Syria and Iraq to U.S.-backed forces, and even as IS leadership was encouraging followers to start looking to progress in IS provinces elsewhere, English-speaking supporters turned to Telegram to reinforce their faith in the caliphate.

The leader of the British Labour Party, Jeremy Corbyn, is an anti-Semite, former British Prime Minister, Tony Blair, said Monday during a visit to Israel. Blair – who was leader of the Labour Party from 1994 and Prime Minister from 1997 until his resignation in 2007 – slammed the “shameful” anti-Semitism crisis that has engulfed his party, when asked if he believed Corbyn himself was anti-Semitic.

Egyptian military and police forces in the Sinai Peninsula are committing serious and widespread abuses against civilians, Human Rights Watch said in a report released Tuesday. Some of these abuses, part of an ongoing campaign against members of the local ISIS affiliate, the Sinai Province group, amount to war crimes.

The April attack on a synagogue in Poway, California, was the latest demonstration of the rise in extremist violence in the United States committed not by “jihadists” inspired by ISIS or other international terrorists, but by white supremacists, neo-Nazis or other right-wing groups. Eric Rosand writes in Lawfare that with the Tree of Life Synagogue attacks still fresh in many Americans’ minds, post-Poway discussions further highlighted how the resources and tools available to prevent right-wing extremist violence or domestic terrorism in the United States are dwarfed by those available to deal with the jihadist-inspired violence that data shows to be a much lesser threat. Rectifying this imbalance requires urgent attention.

By analyzing 26.2 million Twitter comments in the Arabic language, researchers found that despite losing territory, ISIS remains successful at inspiring low-level attacks because of its messaging for a “call for lone jihad.”
