United States–Taliban deal in the context of "2021 Taliban offensive"

The Islamic Republic of Afghanistan was a presidential republic in Afghanistan from 2004 to 2021. The state was established to replace the Afghan interim (2001–2002) and transitional (2002–2004) administrations, which were formed after the 2001 United States invasion of Afghanistan that had toppled the partially recognized Taliban-ruled Islamic Emirate of Afghanistan. However, on 15 August 2021, the country was recaptured by the Taliban, which marked the end of the 2001–2021 war, the longest war in US history. This led to the overthrow of the Islamic Republic, led by President Ashraf Ghani, and the reinstatement of the Islamic Emirate under the control of the Taliban, today the ruling government of Afghanistan. While the United Nations still recognizes the Islamic Republic as the legitimate government of Afghanistan, this toppled government controls no portion of the country. The US–Taliban deal, signed on 29 February 2020 in Qatar, was one of the critical events that caused the collapse of the Afghan National Security Forces (ANSF). Following the deal, the US dramatically reduced the number of air attacks and deprived the ANSF of a critical edge in fighting the Taliban insurgency, leading to the Taliban takeover of Kabul.

Following the September 11 attacks, the United States and several allies invaded Afghanistan, overthrowing the Taliban's first government (which had limited recognition) in support of the opposition Northern Alliance. Afterwards, a transitional government was formed under the leadership of Hamid Karzai. After the 2003 loya jirga, a unitary presidential Islamic republic was proclaimed under a new constitution, and Karzai was elected for a full term as president. Meanwhile, the US-led international coalition helped maintain internal security, gradually transferring the burden of defense to the Afghan Armed Forces after 2013–14.

On 15 August 2021, Afghanistan's capital city of Kabul was captured by the Taliban after a major insurgent offensive that began in May 2021. It was the final action of the War in Afghanistan, and marked a total victory for the Taliban. This led to the overthrowing of the Islamic Republic of Afghanistan under President Ashraf Ghani and the reinstatement of the Islamic Emirate of Afghanistan under the control of the Taliban.

The United States–Taliban deal, signed on 29 February 2020, is considered one of the most critical factors that caused the collapse of the Afghan National Security Forces (ANSF). Following the deal, the US dramatically reduced the number of air attacks and deprived the ANSF of a critical edge in fighting the Taliban insurgency.

The United States Armed Forces completed their withdrawal from Afghanistan on 30 August 2021, marking the end of the 2001–2021 war. In February 2020, the Trump administration and the Taliban signed the United States–Taliban deal in Doha, Qatar, which stipulated fighting restrictions for both the US and the Taliban, and in return for the Taliban's counter-terrorism commitments, provided for the withdrawal of all NATO forces from Afghanistan by 1 May 2021. Following the deal, the US dramatically reduced the number of air attacks on the Taliban to the detriment of the Afghan National Security Forces (ANSF), and its fight against the Taliban insurgency.

The Biden administration's final decision in April 2021 was to begin the withdrawal on 1 May 2021, but the final pull-out of all US troops was delayed until September 2021, triggering the start of the collapse of the ANSF. This collapse led to the Taliban takeover of Kabul on 15 August 2021.
