ABSTRACT
The US government's efforts to counter international and domestic terrorism have evolved, but the pace accelerated during the Obama administration. The issues that faced the Barack Obama administration and will face the Donald Trump administration—as well as the basic policies and programs—have roots in previous generations, some of them dating back to the 1970s and President Richard Nixon's administration. Terrorism kills and wounds people, contributes to refugee problems, threatens both national governments and the traditional international order. Countering terrorism effectively puts a premium on global, regional, and bilateral cooperation and alliances. The Internet, drones, and cyber warfare, with the latter even producing its own form of terrorism—cyber terrorism—have changed the landscape for terrorism and countermeasures. One of the major and particularly troublesome terrorism-related developments during the Obama administration was the emergence of increasingly sophisticated use of the Internet by terrorist groups to spread their propaganda and to radicalize and recruit new supporters, potential suicide terrorists, and other foot soldiers.
