Step-by-step explanation:
When President George W. Bush addressed Congress and the nation on September 20, 2001, he made a case for a new kind of military response; not a targeted air strike on a single training facility or weapons bunker, but a wide-ranging global War on Terror
“Our war on terror begins with al Qaeda, but it does not end there,” said Bush. “It will not end until every terrorist group of global reach has been found, stopped and defeated.”
When American troops invaded Afghanistan less than a month after September 11th, they were launching what became the longest sustained military campaign in U.S. history. The fight in Afghanistan had support from the American people and the backing of NATO allies to dismantle al Qaeda, crush the Taliban and kill Osama bin Laden, the murderous mastermind of the 9/11 attacks.
