The War Powers Resolution, enacted in 1973, was primarily designed to limit the president's authority to commit U.S. armed forces to hostilities without the approval of Congress.

The resolution requires the president to consult with Congress before deploying troops and to notify Congress within 48 hours of such deployment, as well as mandating that military engagement must end within 60 days if Congress does not authorize further action.

This context underscores why the resolution's core aim is to limit presidential power in this arena, making it the correct answer.
