All Policy Analysis by Matthew Levitt

Why do Iranian officials keep ordering hits on U.S. soil in the middle of sensitive negotiations? Because they know they can get away with it.

Despite the potent symbolic benefits of taking out the infamous terrorist ideologue, his death is unlikely to affect the organization’s daily operations, which are increasingly being driven by dangerous affiliates in Africa.

The case highlights the uptick in Iran’s targeting of regime opponents abroad, a trend laid bare in a new data set stretching back four decades.

A panel of leading counterterrorism scholars and practitioners discuss the evolving face of the global jihadist movement amid changes in Washington’s CT posture.

A closer look at the “dirty dozen” individuals and groups that member states should consider as prime candidates for the Security Council’s al-Qaeda, Islamic State, and Taliban designation list.

Over the past decade, Hezbollah has intensified its aggressive activities across the Middle East and now presides over a widening network of proxies.

Three experts discuss the risks of escalating violence on the ground, the Israeli and PA response so far, and U.S. policy options.

On paper, removing the IRGC from just one of several U.S. designation lists would have few if any legal implications—but it's still a terrible idea.

Law enforcement actions and financial designations are appropriate but insufficient—the attacks will not stop without firm diplomatic isolation, travel and study bans on family members of Iranian leaders, and other direct consequences for regime decisionmakers.

Listen to a podcast series shining a bright light on the global terrorist and criminal activities that Lebanese Hezbollah would rather keep hidden from view.

Although domestic extremism has emerged as a bigger homeland terrorist threat, the threat of jihadi violence from abroad remains acute.

The Israeli evidence could reveal a troubling reality wherein groups publicly defend the human rights of some people while supporting acts of terrorism targeting others.

The international community stepped up to the ISIS challenge but has failed miserably to address the multifaceted problems presented by Assad, whose regime has worked with the terrorist group on and off for years.

Reinvesting in civilian capabilities, sharing the burden with other actors, and assessing the widening ideological scope of the extremist threat will be central to any effective program of action.

As Washington recalibrates its costly strategy against violent extremists, its goal should be to reduce terrorism to a low-level threat that law enforcement can handle.

Without years of tolerance and outright support from Damascus, the terrorist network could not have evolved into the powerful organization it became over the past decade.

Shifting away from a U.S.-led military posture will require Washington to repair its damaged credibility with allies abroad and disentangle counterterrorism budgets at home.

As in many other countries, the group has undertaken more than enough terrorist and criminal activity in Australia to justify an expanded listing.
