The fall of Afghanistan to the Taliban in August 2021 was not merely the consequence of a chaotic withdrawal—it was the inevitable result of decades of missteps, miscalculations, and misplaced priorities. The United States didn’t just lose a war; it lost the trust of the Afghan people, turning potential allies into bitter enemies. To understand how the Taliban regained power, we must revisit the long and tangled history of U.S.-Afghanistan relations—a story of alliances forged in necessity, neglected in peace, and ultimately shattered in retreat.
The United States established diplomatic ties with Afghanistan in 1935, and for decades, their relationship remained one of cautious cooperation. During the Cold War, Afghanistan maintained a non-aligned stance, balancing ties with both the United States and the Soviet Union. That balance crumbled in 1978 when a communist coup brought the People’s Democratic Party of Afghanistan (PDPA) to power. The PDPA quickly aligned with Moscow, and within a year, Soviet tanks rolled into Kabul, beginning a decade-long occupation.
In response, the United States launched Operation Cyclone, one of the largest covert CIA programs in history. Billions of dollars in weapons and financial aid flowed into Afghanistan, funneled through Pakistan’s Inter-Services Intelligence (ISI). With support from Saudi Arabia and other allies, the U.S. armed and trained the Afghan mujahideen, a patchwork alliance of resistance fighters united by their opposition to Soviet forces. This strategy worked—the Soviets withdrew in 1989—but the long-term consequences were catastrophic. Once the Soviets were gone, Afghanistan was left heavily militarized, bitterly divided, and ruled by warlords who turned their weapons on one another.
Instead of investing in Afghanistan’s reconstruction, the United States largely turned away. The billions of dollars in military aid dried up, and with it, any serious effort to stabilize the country. In the vacuum left behind, chaos reigned. Warlords carved up the nation into fiefdoms, and civilians suffered under unchecked violence, corruption, and lawlessness. It was from this vacuum that the Taliban emerged, a group of hardline Islamist students and former fighters who promised security, order, and justice. By 1996, they had seized control of Kabul and established their regime.
For years, the United States paid little attention to Afghanistan under Taliban rule. It wasn’t until September 11, 2001, when al-Qaeda operatives—sheltered by the Taliban—carried out the deadliest terrorist attack on U.S. soil, that America returned to Afghanistan with force. The initial mission was clear: dismantle al-Qaeda and remove the Taliban from power. These objectives were achieved quickly, but the war didn’t end. The mission expanded into nation-building, counterinsurgency, and an open-ended military presence that would last two decades.
The United States poured billions into Afghanistan, but much of it was squandered by corrupt officials and contractors. Infrastructure projects were abandoned, schools existed only on paper, and ghost soldiers padded payrolls. Afghan civilians, desperate for stability and tired of broken promises, watched foreign funds vanish while their daily lives remained defined by poverty, fear, and violence. Worse still, the U.S. relied heavily on the very warlords who had terrorized Afghan communities after the Soviet withdrawal. These alliances, made out of short-term necessity, further eroded trust in both the Afghan government and its American backers.
At the same time, America’s reliance on drone strikes and night raids to target Taliban insurgents inflicted deep wounds on Afghan society. Civilian casualties became commonplace, and every mistaken strike or heavy-handed military operation created more Taliban recruits. In Afghanistan’s tribal culture, revenge and honor run deep. When a U.S. drone strike killed an innocent family member, it wasn’t just one Afghan who turned against America—it was an entire family, an entire village. The Taliban exploited these tragedies, framing themselves as protectors of Afghan dignity and sovereignty.
By the time the United States began negotiating its withdrawal in the 2020 Doha Agreement, the Afghan government had already been weakened by years of corruption, mismanagement, and dependence on foreign support. Excluding Afghan officials from key negotiations with the Taliban only further undermined their legitimacy. When American troops finally withdrew in August 2021, the Afghan military—poorly trained, under-equipped, and demoralized—collapsed almost immediately. The Taliban swept across the country with astonishing speed, retaking Kabul without firing a shot.

The chaos of those final weeks will remain one of the most haunting images in modern U.S. history. Afghan allies—interpreters, guides, and civil servants who had risked their lives to support the U.S.—were left behind, desperately clinging to departing planes or hiding from Taliban death squads. For many Afghans, America’s promises of partnership, freedom, and stability had ended in betrayal.
The Taliban’s return to power was not inevitable. It was enabled by decades of U.S. errors: empowering brutal warlords, relying on heavy-handed military tactics, failing to curb corruption, and abandoning Afghanistan in its moments of greatest vulnerability. The war in Afghanistan was not lost on the battlefield—it was lost in conference rooms, policy memos, and the unchecked arrogance of leaders who believed military power alone could reshape a deeply complex society.
The legacy of America’s longest war is not just a failure of strategy; it’s a failure of trust. Afghanistan didn’t need more bombs—it needed accountability. It didn’t need warlords propped up by foreign dollars—it needed honest governance. It didn’t need occupation—it needed partnership.
In the end, wars are not won with weapons alone. They are won by understanding the people, their culture, and their needs. The United States entered Afghanistan with power but left without wisdom. The cost of that failure is etched into the lives of millions of Afghans and will haunt American foreign policy for generations to come.
