Remember the main moments of the 20 years of the US occupation in Afghanistan – 08/30/2021 – World

After 20 years of intervention in Afghanistan, with military occupation, fighting against the extremist Taliban group, changes in American public opinion and a withdrawal full of questions, the US announced this Monday afternoon (30) the end of the withdrawal of its troops of the country.

The mission, the longest war the US has ever been involved in, began in 2001, weeks after the attack on the World Trade Center in New York. The terrorist attack was claimed by the al-Qaeda group, led by Osama bin Laden, then sheltering in Afghanistan — which justified the invasion.

Over the two decades, according to a study by Brown University (USA), about 160,000 people died (of which 2,298 American soldiers, 3,814 mercenaries, 1,145 allies and the rest, Afghans). The cost was $2.26 trillion, a number that the Pentagon puts at around $1 trillion.

Recall some of the main moments of the US occupation of Afghanistan, based on information from the Council on Foreign Relations, an institution that studies US international affairs.


September 11, 2001: Terrorists from the terrorist group Al Qaeda hijack four commercial planes. Two of them crash into the Twin Towers of the World Trade Center in New York; the third crashes into the Pentagon in Washington, and the fourth crashes into a field in Pennsylvania. About 3,000 people died in the attacks. In reaction, the US president at the time, Republican George W.
