By Antonio Salinas   The Cacti and the Grass: The Collapse of Afghanistan's Security Forces Antonio Salinas offers a unique perspective on the collapse of the Afghan National Defense Security Forces (ANDSF) following the U.S. withdrawal from Afghanistan. Through his "Cacti and Grass" analogy, Salinas illustrates how the U.S. attempted to cultivate a Western-style security force in an environment fundamentally unsuited for such structures. Drawing from his personal experiences and extensive research, Salinas examines the cultural mismatches, strategic oversights, and socio-political realities that contributed to the ANDSF's rapid disintegration. This insightful analysis not only sheds light on the complexities of the Afghanistan conflict but also offers valuable lessons for future foreign security assistance efforts.   Antonio Salinas is an active duty Army lieutenant colonel and PhD student in the Department of History at Georgetown University, where he focuses on the history of climate and conflict. Following his coursework, he will teach at the National Intelligence University. Salinas has twenty-five years of military service in the Marine Corps and the United States Army, where he led soldiers in Afghanistan and Iraq. He is the author of Siren’s Song: The Allure of War and Boot Camp: The Making of a United States Marine.   The views expressed are those of the author(s) and do not reflect the official position of the Irregular Warfare Initiative, Princeton University’s Empirical Studies of Conflict Project, the Modern War Institute at West Point, or the United States Government.   If you value reading the Irregular Warfare Initiative, please consider supporting our work.
