Why did the United States and its allies use force against Afghanistan following the attacks on September 11, 2001? Its government was responsible for the attacks. Its government would not hand over bin Laden. Osama bin Laden had fled there after the attacks. All the 9/11 hijackers were from Afghanistan.

"Osama bin Laden had fled there after the attacks."

Explanation:

The war in Afghanistan was a war that initially faced the Islamic Emirate of Afghanistan, ruled by the Taliban, and, once overthrown, its insurgency, on the one hand, and an international coalition commanded by the United States, for control of the Afghan territory, and that continues as War of Afghanistan (2015-present). It began on October 7, 2001 with the "Operation Enduring Freedom" of the US Army and "Operation Herrick" of British troops, launched to invade and occupy the Asian country. The invasion was unleashed in response to the attacks of September 11, 2001 in the United States, of which this country blamed Osama bin Laden. To begin the invasion, the United States relied on a peculiar interpretation of Article 51 of the Charter of the United Nations, on the right to self-defense.

Option C: Osama bin Laden had fled there after the attacks.

The US-led war in Afghanistan began on October 7, 2001, as Operation Enduring Freedom. It was designed to capture or kill Osama bin Laden and al-Qaeda militants, as well as replace the Taliban with a US-friendly government.
