📌 Link to the Text of the Acts

📌 Why They Were Done

•
2001 AUMF: Passed after the September 11 attacks, authorizing the President to use force against nations, groups, or persons responsible for 9/11 or who harbored them.
•
2002 AUMF: Authorized force against Iraq to address Saddam Hussein’s regime and alleged weapons of mass destruction.

📌 Pre-existing Law or Constitutional Rights

The Constitution divides war powers between Congress and the President. These AUMFs served as statutory substitutes for formal declarations of war, last used in WWII.

📌 Overreach or Proper Role?

Supporters argue they gave presidents flexibility to respond to threats. Critics say they created a “blank check” for endless wars, stretched far beyond their original intent.

📌 Who or What They Control

•
President and U.S. Armed Forces (granted broad authority to use force abroad)
•
Congress (ceded significant war powers authority)
•
Foreign states and non-state actors targeted by U.S. military operations
