Its leader, Abu Bakr al‑Baghdadi, declared a pan‑Islamic caliphate and eventually expanded the group to include eight formal provinces; more than a dozen informal provinces; and tens of thousands of inspired individuals across Asia, the Middle East, Africa, Europe, and North America. This report examines the Islamic State and offers a global strategy to roll the group and its movement back. It assesses key coun‑ tries where the Islamic State has controlled territory: Iraq, Syria, Libya, Nigeria, Egypt, and Afghanistan. It also analyzes the group’s global efforts to spread its ideology; move money, material, and people; secure resources; and conduct attacks. The report should be of interest to poli‑ cymakers, academics, and general audiences that want to learn more about the Islamic State and strategies to counter the group.

As an actual, if unrecognized, state, it is on a path to collapse. In Syria and Iraq, the Islamic State controlled approximately 45,377 km2 and roughly 2.5 million people by early 2017, according to RAND Corpo‑ ration estimates compiled in this report. These numbers represented a 56‑percent decline in population for Syria and an 83‑percent decline in population for Iraq from fall 2014 levels. In Egypt, Libya, Afghanistan, and Nigeria, the Islamic State controlled a combined 7,323 km2 and 497,420 people by early 2017. These estimates represented a 75‑per‑ cent drop in population for Nigeria, nearly 100 percent for Libya, and 87 percent in Afghanistan. In Egypt, the Islamic State operated in only a tiny stretch of the Sinai. Polling data also indicated declining support across the Muslim world for the Islamic State and its ideology. Yet even as its core caliphate contracted, the Islamic States estab‑ lished affiliates in the Middle East, Africa, and Asia while, at the same time, directing and inspiring attacks even further afield. The destruc‑ tion of the Islamic State’s territorial base in Iraq and Syria is likely to diminish the group’s wider appeal. Yet it remains possible that the Islamic State, like al‑Qa’ida before it, will continue to metastasize and spread its influence even once it loses its home base. The group’s global footprint includes eight formal provinces outside Iraq and Syria; more than a dozen informal provinces; and tens of thousands of inspired individuals across the world. A sine qua non of the Islamic State’s strat‑ egy is pan‑Islamic expansion across multiple continents. The
