The Anti-Defamation League (ADL) the other day released new data and analysis of 98 Islamist extremist plots and attacks in the United States over the past sixteen years. Among the key findings: the vast majority — a full 90 percent — of the plots and attacks were carried out by U.S. citizens or individuals living in the country with lawful permanent or temporary status.

The Basque militant group ETA has announced it would disband and end its “political initiative” after a 60-year campaign for independence of the Basque region from Spain and France. Spanish officials, however, said they would keep pursuing ETA “terrorists.”

Over the last fifty years, climate change has not been the key driver of the human displacement or conflict in East Africa, rather it is politics and poverty, according to new research. “Terms such as climate migrants and climate wars have increasingly been used to describe displacement and conflict, however these terms imply that climate change is the main cause. Our research suggests that socio-political factors are the primary cause while climate change is a threat multiplier,” said one researcher.

“It is difficult to quantify the extent of Muslim youth radicalization in Britain. Also, we have to be clear about the definition of radicalization. Are we talking about people who are joining extremist organizations or those who just have extremist views? But I agree that there is definitely a general sense that things are not going well here” says an expert on radicalization. “There is no single factor that is driving the youth toward extremism. The issues of identity, alienation, peer pressure, search for a cause, frustration with modernity and acceptance of certain mythological aspects of the Muslim history are all contributing factors.”

An overnight Israeli air strike destroyed more than 200 Iranian mid-range missiles which Iran stored at Syrian military bases near Hama. These missiles were more accurate, and were capable of carrying a bigger warhead, than other missiles available to Hezbollah and the Syrian military. The attack killed 26 military personnel, including 18 Iranian officers. Bashar-al-Assad’s victory in the civil war in Syria has opened the door for Iran, his main ally, to try and turn Syria into an Iranian forward military base against Israel.

Around 80,000 Iran-backed Shi’ite militia members are currently operating in Iraq, a U.S. military official said. “The effect of the Obama administration’s policy has been to replace American boots on the ground with the Iranians,” Thomas Joscelyn, a senior fellow at the Foundation for Defense of Democracies, told Fox News. “As Iran advances, one anti-American actor is being replaced with another.”

A Palestinian engineer whom Hamas claimed worked for them, was shot and killed by unknown assailants in Malaysia where he taught. Hamas, the terrorist organization that exercises complete political and military control over the Gaza Strip blamed Israel for killing Fadi al-Batsh, who was described by the terrorist group’s leader, Ismail Haniyeh, as a member of Hamas with “an honorable reputation in science.”

In the wake of the 9/11 attacks, the U.S. has tightened the vetting of immigrants and foreign travelers. The post-9/11 system has worked: From 2002 to 2016, the vetting system failed and permitted the entry of 1 radicalized terrorist for every 29 million visa or status approvals. Only 1 of the 13 post-9/11 vetting failures resulted in a deadly attack in the United States. Thus, the rate for deadly terrorists was 1 for every 379 million visa or status approvals from 2002 through 2016. During this same period, the chance of an American being killed in an attack committed by a terrorist who entered as a result of a vetting failure was 1 in 328 million per year.

The face of terrorism in the United States has changed dramatically following 9/11. According to a report by the New America Foundation, every jihadist who has conducted a lethal attack inside the United States since 2001 has come from inside the country, already having established citizenship or legal residency. DARPA has launched an ambitious new program called Modeling Adversarial Activity (MAA) which aims to transform the way national security organizations identify emerging threats.
