Answer:
Under the Patriot Act, the U.S. government could send troops to Afghanistan.
Step-by-step explanation:
After the assaults on 11th September in late 2001, the interference of Afghanistan in the US happened and hence, boosted by close US partners. The dispute is otherwise called the war of US in Afghanistan. Its open points were to destroy al-Qaeda, and to disagree from it to be a protected base of tasks in Afghanistan by expelling the Taliban from control.
So, that is why the U.S. government used to send troops or huge groups of people to Afghanistan under the Patriot Act.
