Pentagon Releases Comprehensive Review of 2021 Afghanistan Withdrawal

The Afghanistan Withdrawal Special Review Panel has finished interviewing senior military and civilian officials and is now preparing a final report that Pentagon spokesman Sean Parnell says will be "the most comprehensive military after-action review in modern history" [1]. The panel, established by Defense Secretary Pete Hegseth at President Donald Trump's direction, reviewed more than 9 million documents from multiple agencies — a scope that dwarfs the roughly 3,000 documents examined in the Biden-era review conducted under former Defense Secretary Lloyd Austin [2].

The report's release, expected by summer 2026, arrives nearly five years after the fall of Kabul and against a political backdrop where the incentives to assign blame cross several administrations — and where the architects of the 2020 Doha Agreement that set the withdrawal in motion now hold the power to frame its conclusions.

What the Review Covers — and Who Was Questioned

The panel interviewed more than a dozen high-ranking officials, including former Joint Chiefs Chairman Gen. Mark Milley, former Central Command chief Gen. Kenneth McKenzie, and former Marine Corps Commandant Gen. David Berger [1]. Parnell stated that the review examined "operational planning, intelligence assessments, interagency communications, and post-withdrawal evaluations" [3].

The previous Biden-era review, a classified 87-page State Department document completed in March 2022 and partially released in June 2023, faulted both the Trump and Biden administrations for "insufficient" planning and found that a lack of clear communication "added significantly" to the challenges U.S. personnel faced [4]. A separate declassified CENTCOM after-action review concluded that "indecisiveness among Biden administration officials" and reluctance to close the Kabul embassy "sowed chaos and put the overall mission at increased risk" [5]. Retired Gen. Milley blamed delayed State Department decision-making for the rushed airlift [2].

Parnell has described the Biden-era review as "significantly narrower in scope" and "over-classified at the highest levels, which effectively kept the most critical and relevant information from public scrutiny" [6]. The current panel plans to declassify all sourced documents and interview transcripts [7].

The Intelligence Warnings That Were Received — and Overridden

The collapse of the Afghan government on August 15, 2021, was not a failure of intelligence collection. CIA assessments throughout spring and summer 2021 warned in "increasingly stark terms" about the potential for a rapid, total collapse of the Afghan military and government [8]. By July, a CIA report noted that security forces had lost control of roads leading into Kabul and assessed that the viability of the central government was "in serious jeopardy" [9].

Intelligence assessments delivered in early August warned that Kabul could be isolated within 30 to 60 days, with a more pessimistic scenario estimating collapse within 90 days [10]. Yet as late as one week before Kabul fell, the consensus assessment still held that a Taliban takeover was "not yet inevitable" [8]. President Biden publicly stated on July 8, 2021, that a Taliban takeover was "not inevitable" and that comparing the situation to the fall of Saigon was inaccurate [9].

The gap between what intelligence agencies reported and what senior officials communicated publicly raises a central question for the review: whether leaders received adequate warning and chose to proceed on an optimistic timeline, or whether the intelligence itself failed to convey the speed of the collapse with sufficient urgency. Former CIA counterterrorism officials have argued the latter framing is wrong — calling it "not an intelligence failure" but "something much worse," a failure of policy to act on the intelligence provided [11].

Abbey Gate: 13 Deaths and the Limits of Force Protection

On August 26, 2021, an ISIS-K suicide bomber detonated a vest at Abbey Gate outside Hamid Karzai International Airport, killing 13 U.S. service members and approximately 170 Afghan civilians — at least 182 people in total [12]. A CENTCOM review concluded the bombing "couldn't have been prevented at the tactical level without degrading the mission" [2].

Subsequent reporting by CNN and ProPublica raised questions about the Pentagon's official account, presenting evidence that challenged whether gunfire from U.S. and allied forces after the blast contributed to additional casualties [13]. These questions remain unresolved and are likely to factor into the new review's findings.

NATO Allies' Parallel Operations

The United Kingdom conducted Operation Pitting, evacuating approximately 15,000 people, including around 10,000 eligible Afghans under the Afghan Relocations and Assistance Policy (ARAP) [14]. The UK suffered no combat fatalities during the evacuation itself, though the British armed forces minister acknowledged a "credible, imminent and lethal" ISIS threat that forced the UK to end operations before all eligible individuals could be extracted [15].

In total, the multinational airlift evacuated over 122,000 people from Kabul airport, with U.S., UK, Turkish, and Norwegian forces securing the airfield [14]. Several NATO allies ended their evacuation operations days before the U.S. deadline, partly in response to the Abbey Gate attack and partly because their force footprint was insufficient to operate independently of the American security perimeter. The UK Defence Committee's post-withdrawal report documented failures in its own government's response, indicating the problems were not confined to Washington [14].

$7 Billion in Equipment: What Was Left and Where It Went

The Pentagon confirmed in April 2022 that approximately $7.12 billion worth of military equipment transferred to the Afghan government over 16 years remained in Taliban-held territory [16]. The breakdown by category:

The largest category was military vehicles: more than 40,000 of the 96,000 vehicles provided to Afghan forces, including 12,000 Humvees valued at $4.13 billion [16]. More than 300,000 of the 427,300 weapons supplied to the ANDSF remained in the country [17]. Nearly 42,000 pieces of night-vision, surveillance, and biometric equipment were left behind [16]. "Nearly all" communications equipment — including base-station radios, encryption devices, and hand-held systems — also remained [17].

The Pentagon has emphasized that the 78 aircraft left at Kabul airport, valued at $923 million, were demilitarized and rendered inoperable before the final withdrawal [16]. The operational status of other equipment categories is less clear; the DOD report stated that an "unknown" number of vehicles remained functional [17].

U.S. weapons left in Afghanistan have since surfaced in other conflicts. NBC News reported in 2023 that American-made arms from the Taliban's arsenal had appeared in Kashmir, raising questions about third-party transfers [18]. Open-source intelligence analysts have tracked Taliban use of U.S. equipment in operations, though large-scale verified transfers to Iran or Russia have not been publicly documented.

$90 Billion Spent, Ghost Soldiers Received

The equipment left behind represents only a fraction of the total investment. Over 20 years, the United States spent more than $90 billion on the Afghan National Defense and Security Forces (ANDSF) — an effort the Special Inspector General for Afghanistan Reconstruction (SIGAR) documented as deeply compromised by corruption and inflated accounting [19].

SIGAR's February 2023 report, "Why the Afghan Security Forces Collapsed," found that the stage for the ANDSF's rapid dissolution "had been set years ago by the failure of the U.S. and Afghan governments to create an independent and self-sustainable" force [19]. A persistent problem was "ghost soldiers" — fictitious personnel on government payrolls. A 2016 SIGAR report found that of the roughly 350,000 ANDSF troops nominally on the payroll, an estimated 200,000 did not exist [20]. After the collapse, Afghanistan's former finance minister estimated the real number may have been as low as 50,000 — meaning up to 80% of the force was fictional [20].

Inspector General reports spanning the Obama, Trump, and Biden administrations repeatedly flagged Afghan force readiness as a critical risk. These warnings went largely unaddressed. SIGAR's December 2025 final report, a forensic audit covering the entire 20-year mission, concluded that decades of U.S. funding were undermined by "corruption, ghost-salary schemes, and an inability to maintain complex gear" [21].

Those Left Behind: The Human Cost Since August 31, 2021

When the last U.S. aircraft departed Kabul on August 30, 2021, an unknown but significant number of American citizens, legal permanent residents, SIV applicants, and Afghan allies remained in the country. As of August 2025, U.S. government data showed 178,110 individuals had received Chief of Mission approval — the formal determination of SIV eligibility — but had not yet been interviewed or had their visas issued [22].

The situation for those left behind has worsened. UNAMA documented at least 800 violations against former government officials and ANDSF members between August 15, 2021, and June 30, 2023, including 218 killings, 14 enforced disappearances, 424 arrests or detentions, and 144 cases of torture or ill-treatment [23]. At least 110 former ANDSF members — including elite commandos who partnered with U.S. and UK special forces — have been killed since 2023 [24]. The Taliban's declared amnesty has proved hollow.

Afghanistan now ranks as the third-largest source of refugees globally, with 4.8 million displaced abroad as of 2025, trailing only Syria (5.5 million) and Ukraine (5.3 million) [25].

The Trump administration's immigration policies have further complicated resettlement. Effective January 1, 2026, Presidential Proclamation 10998 fully suspended visa issuance to Afghan nationals, including SIV holders [22]. Temporary Protected Status for Afghans was terminated on July 12, 2025, placing nearly 8,000 individuals at risk of deportation [26]. A federal court ruled on February 6, 2026, that entry restrictions do not eliminate the government's obligation to continue processing SIV cases already in the system [22], but tens of thousands of approved applicants remain stranded in Afghanistan and Pakistan with no funded travel pathway.

The Doha Agreement: Where Accountability Begins

Any credible accounting of the withdrawal must start with the February 29, 2020, Doha Agreement between the Trump administration and the Taliban. Negotiated by Special Envoy Zalmay Khalilzad, the deal excluded the Afghan government entirely [27]. Its terms committed the U.S. to withdraw all forces by May 1, 2021, in exchange for Taliban pledges to prevent al-Qaeda operations in Taliban-controlled areas and to enter negotiations with the Afghan government [28].

The agreement also required the release of up to 5,000 Taliban prisoners — a concession that Afghan President Ashraf Ghani opposed but ultimately implemented under U.S. pressure [27]. Insurgent attacks against Afghan security forces surged after the deal was signed, even as U.S. troop levels dropped from 13,000 to 2,500 by January 2021 [28].

Former Trump administration officials have distanced themselves from the deal's consequences. In August 2021, as the withdrawal descended into chaos, several former officials publicly backed away from the agreement they had negotiated [29]. The current review's credibility depends in part on whether it examines these antecedent conditions with the same rigor it applies to the Biden administration's execution of the withdrawal.

Political Context: Who Reviews the Reviewers?

The review is being conducted under a Republican administration with clear political incentives to assign maximum blame to its predecessor. Several structural features raise questions about independence:

Leadership: Sean Parnell, who chairs the panel, serves as the Pentagon's chief spokesman — not a role traditionally associated with leading investigations into military operations. Parnell is a combat veteran who served in Afghanistan, but he is also a political appointee with close ties to the Trump administration [6].

Institutional framing: The Pentagon has been rebranded the "Department of War" under the current administration, a nomenclature shift that itself signals a political orientation [1].

Scope decisions: The panel's stated purpose is to "identify failures in decision-making so that we may prevent the United States from ever repeating this tragedy" [3]. Whether "failures" are defined to include the Doha Agreement's structural flaws or confined to the 2021 execution window will determine whether the report reads as a comprehensive assessment or a partisan document.

The Biden-era State Department review, for its part, did apportion blame across administrations, finding that "during both administrations there was insufficient senior-level consideration of worst-case scenarios" [4]. If the current review narrows its lens to August 2021 without examining the conditions established in 2020, its conclusions will be incomplete regardless of how many documents it cites.

The Credibility Deficit: Long-Term Costs

Beyond the immediate human and material losses, military and intelligence officials have warned that the manner of the withdrawal damaged U.S. credibility with potential allies in future conflicts. The abandonment of Afghan interpreters, commandos, and intelligence assets who worked alongside American forces sends a signal to prospective partners elsewhere.

No One Left Behind, an advocacy organization, documented over 300 interpreters or their family members killed in Afghanistan because of their U.S. service — a figure they described as an undercount [24]. The long-term cost of rebuilding the trust necessary to recruit local partners in future operations has not been formally quantified by the Pentagon, but defense analysts have noted that the withdrawal's aftermath was cited by adversaries — including Russian and Chinese state media — as evidence that American security guarantees are unreliable.

The SIGAR final report, released in December 2025, put it bluntly: two decades and $90 billion produced security forces that collapsed in 11 days [21]. Whether the new review grapples with that systemic failure — or treats August 2021 as an isolated event — will determine whether it contributes to accountability or merely to the political cycle.

What to Watch For

The final report is expected within months. Key indicators of its credibility will include: whether it assigns responsibility for the Doha Agreement's structural weaknesses alongside the withdrawal's execution failures; whether it addresses the 20-year pattern of SIGAR warnings that went unheeded; whether the declassified materials include documents unfavorable to the current administration's narrative; and whether its recommendations address the ongoing abandonment of SIV holders whose cases remain frozen under current immigration policy.

The 13 service members killed at Abbey Gate, the estimated 218 former Afghan allies killed in Taliban reprisals, and the 4.8 million Afghan refugees worldwide represent costs that no review can reverse. The question is whether this one can produce findings honest enough to prevent the next version of the same failure.
