A new report by the Special Inspector General for Afghanistan Reconstruction (SIGAR) has delivered a scathing assessment of the United States’ 20-year involvement in Afghanistan. Released on 3 December 2025, the report concludes that Washington’s effort to build a democratic system “became a massive cycle of corruption, waste, and abuse of billions of dollars.”
According to SIGAR, the U.S. government spent more than $148 billion in its failed attempt to build a free Afghanistan. This figure exceeds even the post-World War II Marshall Plan. The watchdog’s careful documentation of waste, fraud, and warnings about Taliban resurgence largely went unheeded. Yet, instead of creating functional governance, the money helped establish what SIGAR’s acting head, Gene Aloise , described as “essentially a giant criminal enterprise.”
Rampant Corruption and Financial Mismanagement
The report documents 1,327 cases of corruption, embezzlement, and fraud, totaling $29.2 billion in losses. Millions were wasted on projects, aircraft, and buildings that were never used or abandoned shortly after completion. Both American and Afghan contractors siphoned off billions through bribery, fraudulent contracts, and theft.
Some individuals associated with U.S. intelligence operations were reportedly “immune from prosecution.” SIGAR cites incidents such as an Afghan businessman paying $1.25 million in bribes to U.S. personnel to smuggle fuel, and an American contractor couple failing to pay taxes on hundreds of millions earned from Afghan contracts.
Military Equipment Left Behind
The United States spent $38.6 billion on Afghan military equipment, including:
-
96,000 military vehicles
-
427,000 weapons
-
162 aircraft
-
17,400 night-vision devices
After the U.S. withdrawal, $7.1 billion in equipment remained in Afghanistan, much of it likely under the control of the Islamic Emirate (Taliban). Reports confirm that US-made weapons are now appearing in black markets and are reportedly in high demand among militant groups, including al-Qaeda affiliates and the Tehreek-e-Taliban Pakistan (TTP). BBC estimates that half a million Taliban-obtained weapons have been lost, sold, or smuggled to other militant groups.
Non-Cooperation and Recognition of Failure
SIGAR faced persistent obstacles in obtaining information from U.S. officials, with non-cooperation peaking under the Biden administration, Gene Aloise noted: “They shut us out for an entire year—no interviews, no data, nothing.” Several former U.S. officials admitted they had long understood that the Afghanistan project was “destined to fail.”
Human Cost of Two Decades of War
According to the Brown University Costs of War project, the human toll of the conflict includes:
-
2,320 U.S. service members killed
-
69,000 Afghan security forces killed
-
46,000 civilians killed
SIGAR’s Final Verdict
The report concludes that the cost of the war extended far beyond money, highlighting that billions were wasted and institutions built by the U.S. collapsed within days of withdrawal. SIGAR’s warnings of corruption, waste, and Taliban resurgence went largely ignored.
