Which U.S. law limited the President's power to wage war without congressional authorization?

• A. Domino Theory
• B. War Powers Act
• C. Ho Chi Minh
• D. Geneva Accords

Answer: (B)

The main idea here is how the U.S. government checks presidential power to wage war. The War Powers Act of 1973 was designed to curb unilateral military action by requiring Congress to authorize extended use of force and to keep Congress in the loop. It requires the President to consult with Congress before deploying armed forces, to report to Congress within 48 hours of sending troops, and to withdraw those forces within 60 days (with a possible 30-day extension) unless Congress declares war or authorizes a longer deployment. This creates a legal mechanism for Congress to oversee and limit the President’s ability to wage war without its approval, reflecting the constitutional balance between the branches.

The other options aren’t about limiting presidential war powers. The Domino Theory is a Cold War idea about communism spreading, Ho Chi Minh is a Vietnamese leader, and the Geneva Accords were international agreements, not U.S. law restricting presidential authority.
