In a series of tweets Monday morning, President Donald Trump, following a phone call with Recep Tayyip Erdogan of Turkey, announced the United States would withdraw its remaining forces from northern Syria, and that he had given a green light to Turkey to enter Syria to deal with Kurdish forces there. These forces had been instrumental in helping the United States defeat the Islamist State in Syria, and are now holding about 11,000 ISIS fighters – about 2,000 of them foreign fighters – in thirty detention centers. The Kurdish forces are regarded as terrorists by Turkey. Robert Chesney writes that the White House statement, issued after Trump’s tweets, “treats [the problem of the ISIS detainees] in a way that is far more alarming than comforting”: “It is possible that all this hand-wringing will prove unwarranted. Perhaps Turkey’s military incursion will be limited, leaving the Kurds capable and willing to continue detaining Islamic State fighters. Perhaps vast numbers of the detainees will be dispatched to Iraq for prosecution after all (a much-touted plan a year ago, about which little has surfaced since). Perhaps Turkey will somehow gain control of and maintain detention operations. Anything is possible. But none of that seems likely. More likely, the biggest beneficiary of all this will be the Islamic State.”

There has never been a bright line between word and deed. Yet, for years, the founders of Facebook and Twitter and 4chan and Reddit tried to pretend that the noxious speech prevalent on those platforms wouldn’t metastasize into physical violence. Andrew Marantz writes in the New York Times that in the early years of this decade, back when people associated social media with Barack Obama or the Arab Spring, Twitter executives referred to their company as “the free-speech wing of the free-speech party.” “No one believes that anymore,” Marantz writes. Marantz says that after spending the past few years embedded as a reporter with the trolls and bigots and propagandists who are experts at converting fanatical memes into national policy, “I no longer have any doubt that the brutality that germinates on the internet can leap into the world of flesh and blood.” He adds: “The question is where this leaves us. Noxious speech is causing tangible harm. Yet this fact implies a question so uncomfortable that many of us go to great lengths to avoid asking it. Namely, what should we — the government, private companies or individual citizens — be doing about it?”

Later this year, a U.S. service member is likely to be deployed to Afghanistan who was not yet born on September 11, 2001, when al-Qaeda terrorists launched the most devastating terrorist attack in history and killed almost 3,000 people, mostly Americans. The years in between have seen wars in Iraq and Syria justified in the name of counterterrorism as well as more limited U.S. interventions against jihadi groups in Libya, Somalia, and other countries. “Hundreds of thousands have died in these conflicts—some from terrorism, but most from combat and the associated ravages of war,” Daniel Byman writes. “Yet even as this body count soared, neither al-Qaeda nor other jihadi groups have proven able to conduct a repeat of 9/11 or even anything close to it.” He notes that judging the threat that jihadi terrorism currently poses to the United States and, more broadly, the success of the U.S.-led struggle against various jihadi groups in the post-9/11 era depends on what interests are prioritized and which perspective one takes. “Before Americans celebrate or despair, however, it is useful to take stock of the problems facing the main jihadi organizations themselves.”

In the past, incidents of white nationalist violence haven’t garnered the attention they deserve from Congress or federal law enforcement. But after the August 2019 El Paso shooting by a young white supremacist, Reps. Adam Schiff (D-CA) and Randy K. Weber Sr. (R-TX) introduced two separate bills that would create a new crime of domestic terrorism, citing lethal white nationalist crimes as the justification. Faiza Patel writes for the Brennan Center that while it’s reassuring, and long overdue, for members of Congress to take the threat of white nationalist violence seriously, such legislation is both unnecessary and creates serious risks of abuse.

In December 2018, US President Donald Trump declared victory over the Islamic State in Iraq and Syria, tweeting that ‘ISIS is largely defeated and other local countries, including Turkey, should be able to easily take care of whatever remains. We’re coming home!’ And in the first three months of this year, Trump said or tweeted 16 times that IS was either completely defeated or soon would be. But the United States government appears to disagree. In August, the three lead inspectors general from the Department of Defense, the Department of State and the US Agency for International Development submitted a joint report to Congress reviewing Operation Inherent Resolve, the US campaign to defeat IS, over the period from 1 April through 30 June of this year. They concluded that, ‘Despite the loss of physical territory, thousands of ISIS fighters remain in Iraq and Syria and are carrying out attacks and working to rebuild their capabilities.’

A commando raid on a nuclear power plant seems the stuff of Hollywood. So why are nuclear security experts so worried? It ranks among the worst-case scenarios for a nuclear power plant: an all-out assault or stealth infiltration by well-trained, heavily armed attackers bent on triggering a nuclear blast, sparking a nuclear meltdown or stealing radioactive material. Under pressure from a cash-strapped nuclear energy industry increasingly eager to slash costs, the commission in a little-noticed vote in October 2018 halved the number of force-on-force exercises conducted at each plant every cycle. Four months later, it announced it would overhaul how the exercises are evaluated to ensure that no plant would ever receive more than the mildest rebuke from regulators – even when the commandos set off a simulated nuclear disaster that, if real, would render vast swaths of the U.S. uninhabitable. Nuclear security experts, consultants, law enforcement veterans and former NRC commissioners are nothing short of alarmed. “You can’t afford to be wrong once,” says one expert.

To counter the rise of violent far-right terrorism in the U.S., the federal government should strengthen its partnerships with civilian researchers and embrace a public health approach for at-risk individuals, terrorism expert told a congressional committee.

Europol, the European police agency, issued a “Strategic Report” earlier Tuesday, saying that right-wing violence is on the rise in many EU states. The confidential report, cited by German media, says that the extremist groups seek to boost their “combat skills” by recruiting military and police members. The report noted that extremist groups are getting “increasingly popular among younger and better educated demographics.”

On 18 August 2008—after almost seven years, nearly 10,000 interviews, and millions of dollars spent developing a whole new form of microbial forensics—some of the FBI announced that it had concluded that Army biodefense researcher Bruce Ivins was the person responsible for the fall 2001 anthrax letter attacks. “It’s been 10 years since the deadliest biological terror attack in U.S. history launched a manhunt that ruined one scientist’s reputation and saw a second driven to suicide, yet nagging problems remain,” Noah Shachtman writes. “Problems that add up to an unsettling reality: Despite the FBI’s assurances, it’s not at all certain that the government could have ever convicted Ivins of a crime.”
