What was the reason for Afghanistan War?

The War in Afghanistan (2001–2021), also known as the Afghan War, Operation Enduring Freedom, and Operation Freedom's Sentinel, was a conflict that began on October 7, 2001, when U.S. President George W. Bush ordered an invasion of Afghanistan in response to the September 11 attacks on the United States.

The stated goals of the U.S.-led invasion were to:

- Dismantle al-Qaeda and its safe haven in Afghanistan

- Capture or kill Osama bin Laden, the leader of al-Qaeda

- Topple the Taliban regime, which had provided support and sanctuary to al-Qaeda

The war in Afghanistan was the longest war in U.S. history and one of the most expensive. It resulted in the deaths of thousands of Afghan civilians, U.S. soldiers, and coalition forces, as well as the displacement of millions of Afghans.

The war also had a significant impact on Afghanistan's political, social, and economic development. The Taliban regime was overthrown, but the country remains plagued by corruption, poverty, and violence. The war has also contributed to the rise of extremist groups in the region, such as the Islamic State of Iraq and Syria (ISIS).

The war in Afghanistan ended on August 30, 2021, when the United States and its allies withdrew from the country. The Taliban quickly took control of the country, and the U.S.-backed Afghan government collapsed.

The war in Afghanistan has left a lasting legacy of violence, instability, and poverty in the country. The future of Afghanistan remains uncertain, but it is clear that the war has had a profound impact on the country and the region.
