Twenty-Five Years On: Why Guantanamo Bay Prison Remains Open Despite the End of the Afghanistan War

The United States military detention facility at Guantanamo Bay, Cuba, continues to operate a quarter-century after it was first established, even though the conflict that prompted its creation has formally concluded. Al Jazeera, in a video report published on October 8, 2026, examined the persistent question of why the prison has not been shuttered despite the end of the war in Afghanistan. The facility, which once held hundreds of detainees, remains a subject of international scrutiny and debate.

Guantanamo Bay opened its detention operations in the aftermath of the US invasion of Afghanistan in 2001. The invasion followed the September 11 attacks, and the facility was intended to hold individuals captured in connection with the ensuing global campaign against militant groups. At its peak, the prison housed hundreds of detainees, many of whom were transferred from battlefields in Afghanistan and elsewhere. The legal framework under which they were held became a source of widespread controversy.

The prison's founding was rooted in a legal designation that placed detainees outside the protections typically afforded by the US criminal justice system. The Bush administration at the time argued that those held at Guantanamo were "enemy combatants" and not entitled to the full rights of prisoners of war under the Geneva Conventions. This classification allowed for indefinite detention without formal charges or trials, a practice that drew condemnation from human rights organizations, legal scholars, and many foreign governments.

Over the years, the number of detainees has declined significantly. From a peak of several hundred, the population has been reduced to a small fraction of that figure through transfers to third countries, repatriations, and a limited number of releases. Despite this reduction, the facility has never been fully closed. Successive US administrations, both Republican and Democratic, have grappled with the logistical, legal, and political obstacles to shutting it down.

One central obstacle has been the question of what to do with detainees who are deemed too dangerous to release but who cannot be prosecuted in civilian courts. Some of these individuals are alleged to have been involved in high-level planning of attacks against the United States and its allies. The evidentiary challenges, including the use of information obtained through enhanced interrogation techniques, have complicated efforts to bring them to trial. As a result, some detainees have remained in limbo for years without charge.

The facility has also been the subject of intense legal battles. The US Supreme Court has issued multiple rulings addressing the rights of Guantanamo detainees, including decisions that granted them the ability to challenge their detention in federal courts. These rulings have shaped the legal landscape but have not led to the facility's closure. The military commissions system established to try some detainees has been slow, controversial, and repeatedly challenged on due process grounds.

Al Jazeera's Noor Wazwaz, in the video report, highlighted the anomaly of a prison that remains open long after the war that spawned it has ended. The report noted that the conflict in Afghanistan, which began in 2001, was formally concluded with the US withdrawal in 2021. Yet the detention facility, located on a leased naval base in Cuba, continues to hold prisoners. This disconnect between the end of hostilities and the continuation of detention has fueled arguments that the facility's ongoing operation is no longer justified by the original rationale.

Critics argue that the prison has become a symbol of the erosion of legal norms and the persistence of a security apparatus that outlives its stated purpose. They contend that keeping Guantanamo open undermines the United States' credibility when it criticizes other nations for human rights abuses. The facility has been cited by extremist groups as a recruiting tool, and its continued existence has complicated diplomatic relations with allied countries that have refused to accept transferred detainees.

Supporters of the facility, however, maintain that it serves a necessary function in detaining individuals who pose a genuine threat and who cannot be safely released or easily prosecuted. They point to the risks of recidivism among released detainees and argue that the alternative of transferring them to US soil would create security and legal complications. Some lawmakers have opposed closing Guantanamo on the grounds that it would bring dangerous individuals into American communities or require building a new detention facility within the United States.

The political dimension of the debate has proven intractable. President Barack Obama famously signed an executive order to close the facility within a year of taking office, but the plan was blocked by Congress, which passed legislation restricting the transfer of detainees to the US mainland. Subsequent administrations have offered varying degrees of support for closure, but none has succeeded in overcoming the legislative and logistical hurdles. The result has been a stalemate that has persisted across multiple presidencies.

International human rights organizations, including Amnesty International and Human Rights Watch, have repeatedly called for the facility's closure. They have documented allegations of torture, indefinite detention, and denial of fair trial rights. United Nations experts have also urged the United States to close the prison and either release or fairly prosecute the remaining detainees. These calls have gone unheeded, and the facility remains operational as of the Al Jazeera report's publication date.

The financial cost of maintaining Guantanamo Bay is another factor in the debate. Operating the detention facility runs into hundreds of millions of dollars annually, a figure that critics say is disproportionate to the small number of detainees still held there. The per-detainee cost is extraordinarily high, and some analysts argue that the money could be better spent on domestic security or rehabilitation programs. Yet the political will to close the facility has not materialized.

As the twenty-fifth anniversary of the facility's opening approaches, the question posed by Al Jazeera remains unanswered. The war in Afghanistan is over, but the prison built in its shadow persists. The remaining detainees face an uncertain future, and the legal and political frameworks that keep them confined remain firmly in place. For now, Guantanamo Bay endures as a lasting legacy of a conflict that has ended but whose consequences continue to reverberate.
