Today's terrorist landscape is more fluid and complex than eve r. For this reason, counterterrorism remains a top priority for this Administration. Our principal terrorist enemies are radical Islamist terrorist groups that seek to conduct attacks globally, violate our borders, and radicalize and recruit potential extremists within the United States and abroad. We continue to face threats from Iran, the most prominent state sponsor of terrorism, through its global network of operatives and its ongoing support to an array of terrorist groups. Terrorists motivated by other forms of extremism also use violence to threaten the home land and challenge United States interests. These terrorist threats are different in many ways, but they all seek to use violence to undermine the United States and disrupt the American way of life.

The National Strategy for Counterterrorism recognizes the full range of terrorist threats that the United States confronts within and beyond our borders, and emphasizes the use of all elements of national power to combat terrorism and terrorist ideologies. It enhances our emphasis on targeting terrorist networks that threaten the United States and our allies and on disrupting and denying their ability to mobilize, finance, travel, communicate, and inspire new followers. We will deny terrorists the freedom to travel and communicate across international borders, and we will take action to limit their ability to recruit and radicalize online. We will combat the violent, extreme, and twisted ideologies that purport to justify the murder of innocent victims. We will also ensure that America’s critical infrastructure is protected, in order to deter and prevent attacks, and is resilient so that we can quickly recover should it come under attack.
