Final answer:
Congress passed the War Powers Resolution of 1973 to limit the president's ability to engage in military conflict without congressional approval, requiring the president to seek consent for any engagement longer than sixty days.
Step-by-step explanation:
The War Powers Resolution of 1973 was passed by Congress to reassert its role in the war decision-making process, which had largely been dominated by the Executive Branch since World War II. This congressional action followed the United States' involvement in several conflicts, such as the Korean and Vietnam Wars, without a formal declaration of war.
The Resolution meant to limit the president's power by requiring congressional approval for any military engagement lasting over sixty days. Despite this, the War Powers Act inadvertently clarified the president's ability to engage in military action without immediate congressional approval, strengthening the president's war-making role for short-term conflicts within the sixty-day window.
