Final answer:
The War Powers Act of 1973 altered the constitutional framework for war-making by requiring presidential notification and Congressional approval for military actions, aiming to reinforce Congressional authority but also potentially enhancing presidential power.
Step-by-step explanation:
The War Powers Act of 1973 significantly altered the framework within which the rules of war are decided in the United States, as outlined in the U.S. Constitution. Its major provisions include requirements for the President to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without an authorization of the use of military force or a declaration of war by Congress. This aimed to curb the presidential power to make war, which had expanded during conflicts such as Korea and Vietnam, without the formal declaration from Congress that the Constitution mandates.
Furthermore, while the resolution intended to reclaim Congress's constitutional authority over war-making, it is argued that it paradoxically may have strengthened the role of the President by allowing unilateral military action without Congressional approval for up to sixty days. The shifting balance of power reflects evolving interpretations of the Constitution, where 20th-century views have lent towards a more flexible and adaptable approach to its application.
