The Vandenberg Coalition Afghanistan Working Group convened a diverse group of national security professionals to develop policy recommendations for the Biden administration and Congress in the wake of the 2021 Afghanistan crisis. Members of the working group included former government officials, military veterans, and academics with substantive expertise in a range of areas including Afghanistan, China, Iran, India, Pakistan, Russia, counterterrorism, sanctions, humanitarian aid, and human rights. The group met from September 2021 to February 2022 to discuss the major consequences of the crisis for U.S. national security and to develop forward–looking proposals. In addition to offering several policy recommendations, the group’s work highlights points of failure in the 2021 U.S. withdrawal from Afghanistan with the intention of ensuring that the deadly mistakes of this crisis never again occur.
