organization Al-Qaeda, and issued an ultimatum to the Taliban regime in Afghanistan, where bin Laden was operating, to "hand over the terrorists, or... share in their fate". On October 7, 2001, the US led a NATO invasion of Afghanistan, instigating the global war on terror and what became the early phase of the US led-coalition War in Afghanistan. President Bush confirmed the strikes in his address to the nation, Bush stated that "Taliban military sites and terrorist training grounds would be targeted". "Food, medicine and supplies would be dropped to the starving and suffering men, women and children of Afghanistan". NATO forces scoured the region for 9/11 alleged mastermind Osama Bin Laden and his terrorist network Al-Qaeda and drove the fundamentalist Islamic Taliban regime, which was sheltering and providing sanctuary for Bin Laden and Al-Qaeda, from power.

Both Afghanistan and the United States resumed diplomatic ties in late 2001. In 2002, based on UNICEF figures, Nicholas Kristof reported that "our invasion of Afghanistan may end up saving one million lives over the next decade" as the result of improved healthcare and greater access to humanitarian aid.
