What happened in the aftermath of both attacks on the US?

In the aftermath of the September 11, 2001 attacks, the U.S. launched the War on Terror, initiating military operations in Afghanistan to dismantle al-Qaeda and remove the Taliban from power. Domestically, there was a significant increase in security measures, including the establishment of the Department of Homeland Security and the implementation of the USA PATRIOT Act. Following the attack on Pearl Harbor on December 7, 1941, the U.S. entered World War II, mobilizing its military and economy in a full-scale war effort against the Axis powers. Both events led to profound societal changes and lasting impacts on U.S. foreign and domestic policies.
