The year 2020 has featured an array of safety and security concerns for ordinary Americans, including disease and natural disasters. How can the U.S. government best protect its citizens? That is the focus of a new scholarly book with practical aims, Beyond 9/11: Homeland Security for the Twenty-First Century, The volume features chapters written by 19 security experts, and closely examines the role of the Department of Homeland Security (DHS), which was created after the September 2001 terrorist attacks on the U.S.

Foreigners are still networking, training and fighting on both sides of the conflict in eastern Ukraine, cultivating skills and connections that strengthen the transnational white-supremacy extremist networks of today—which, though far from monolithic, are more violent, more organized and more capable than even five years ago.

A new report by RAND’s Brian Michael Jenkins answers the following questions:1) What is the collective profile of Americans traveling or attempting to travel abroad to join jihadist groups? 2) Among Americans associated with terrorism or terrorist organizations, are there significant differences in the demographics or backgrounds that propelled some to go abroad and some to instead join the jihadist movement at home? 3) What can the collective profile of America’s jihadists reveal about the dimensions and nature of the terrorist threat, the statistical profile of those who respond to jihadist recruiting appeals, the effectiveness of the U.S. response to the threat, and the results of that response?

The 17 September hearing on “Worldwide Threats to the Homeland,” as its title suggests, does not make for happy watching. Daniel Byman and Seamus Hughes write that, indeed, statements by FBI Director Christopher Wray and National Counterterrorism Center Director Christopher Miller duly assess an array of dangers related to national security, including election interference, a more aggressive Russia and China, and emergent technologies. Most of their remarks, however, focused on terrorist groups and networks and the threats they pose. “The biggest danger the directors warned about is from lone actors who self-radicalize and act on their own.” Byman and Hughes write. “Wray warned that the most recent uptick is from anti-government violent extremists, some of whom have white supremacist views but many of whom, like the Three Percenters and boogaloos, see themselves as patriots fighting government ‘tyranny’.”

The Network Contagion Research Institute (NCRI), a non-partisan organization, developed a tool to analyze extremist discourse on social media, and earlier this year used it to analyze the growing threat posed by the far-right, anti-government Boogaloo Bois movement. NCRI has now released a study of the increasingly more extreme social media discourse by leftist extremists.

The increasingly militant social media discourse by anarcho-socialist extremists is worrisome, even if far-left extremists are not viewed by security experts inside and outside government as posing as much of a domestic terrorism threat as do far-right extremists and Islamist jihadists — at least not yet. A new report by the Network Contagion Research Institute (NCRI) – a sequel to an earlier report on Boogaloo Bois — analyzes the increasingly militant languages of social media postings by anarcho-socialists, noting that on the far-right violent words preceded violent actions. It may be the case on the far-left as well.

Usually good for a conspiracy theory or two, President Donald Trump has suggested that the virus causing COVID-19 was either intentionally engineered or resulted from a lab accident at the Wuhan Institute of Virology in China. Scientists have now conclusively proved that the virus was not designed in a lab, but Vivek Wadhwa writes that if “genetic engineering wasn’t behind this pandemic, it could very well unleash the next one. With COVID-19 bringing Western economies to their knees, all the world’s dictators now know that pathogens can be as destructive as nuclear missiles.”

Nineteen years after the 9/11 attacks, Americans’ ideas of what terrorism is remain tied to that morning. But focusing solely on Islamist extremism groups like al-Qaeda when investigating, researching and developing counterterrorism policies does not necessarily align with what the numbers tell us. Homegrown far-right extremism also poses a persistent and lethal threat to the lives and well-being of Americans. This risk is often underestimated because of the devastating impact of the 9/11 terrorist attacks. It is imperative to support policies, programs and research aimed at countering all forms of violent extremism.

White supremacists present the gravest terror threat to the United States, according to a draft report from the Department of Homeland Security. Betsy Woodruff Swan writes in Politico that two later draft versions of the same document — DHS’s State of the Homeland Threat Assessment 2020 — describe the threat from white supremacists in slightly different language. “But all three drafts describe the threat from white supremacists as the deadliest domestic terror threat facing the U.S., listed above the immediate danger from foreign terrorist groups.” Woodruff Swan notes that “None of the drafts Politico reviewed referred to a threat from Antifa, the loose cohort of militant left-leaning agitators who senior Trump administration officials have described as domestic terrorists.”
