The implications of the War Powers Act for U.S. presidents revolve around the limits it places on their ability to engage in military action without congressional approval. Enacted in 1973, the Act requires the president to notify Congress within 48 hours of military deployment and restricts armed forces' engagement to 60 days without formal consent from Congress. This legislation aims to check the executive branch's power, ensuring that decisions regarding military action reflect the will of the legislature and, by extension, the public, thereby promoting accountability.
