Al Qaeda and ISIS: Existential Threats to the U.S. and Europe

The Institute for the Study of War and AEI's Critical Threats Project conducted an intensive multi-week exercise to frame, design, and evaluate potential courses of action that the United States could pursue to defeat the threat from ISIS and al Qaeda in Iraq and Syria. This first report examines America’s global grand strategic objectives as they relate to ISIS and al Qaeda and considers the nature of those enemy groups in depth and in their global context.

Regime and Iranian Forces Launch Multi-Pronged Offensive in Aleppo

The Syrian regime and its allies launched a major, multi-pronged offensive in Aleppo Province on October 15 in order to bolster the regime's foothold in Aleppo City. Both Russia and Iran likely aim to enable Syrian President Bashar al-Assad to reassert control over Syria’s largest city given the heavy involvement of their military forces in these operations.

Pro-regime Forces in Idlib Posture for Resumption of Offensive

The ceasefire in Greater Idlib remains tenuous. Recent force disposition indicates that the Syrian Regime is preparing for a renewed offensive in Southern Idlib Province should the ceasefire break down, but both the timing and likelihood of the offensive’s success remain uncertain and conditions dependent. A renewed regime offensive will require Russian support to sustainably seize territory from anti-Assad forces. However, Russian support will likely be contingent on a new negotiated agreement between Russia and Turkey, and the COVID-19 pandemic will likely delay such negotiations. The Syrian regime may attempt an offensive without Russian support despite the likelihood that it will be unsuccessful. Any regime offensive, whether Russian-backed or unilateral, will exacerbate the ongoing humanitarian crisis in Greater Idlib.

Turkey Commits to Idlib

The U.S. has an opportunity in Idlib to exploit the largest rift between Turkey and Russia in Syria to date while addressing a grave and dangerous humanitarian crisis, which will worsen in coming months without a robust international response. Turkey’s intervention in Idlib Province changed the military balance in northwest Syria and created an opportunity for the U.S. and Europe to engage at relatively low cost.

A Way Forward in Syria

ISW Board Chairman Jack Keane and Danielle Pletka: The president stood by his word and didn’t tolerate the Syrian dictator’s use of weapons of mass destruction. But while the recent strike on Syria was important and necessary—it was far from sufficient.
