Who can limit the President's powers to send troops to other countries?

The ability to limit the President's power to send troops abroad lies significantly with both the Senate and the House of Representatives, which is why the answer is both legislative bodies. According to the War Powers Resolution of 1973, the President can deploy military forces but must notify Congress within 48 hours and cannot engage in military action for more than 60 days without Congressional authorization. This creates a necessary check on the executive branch's ability to engage in armed conflict unilaterally.

The Senate and House of Representatives together have the constitutional authority to declare war, and their collective permission is required for any prolonged military engagement. This power serves as a critical oversight mechanism to prevent unilateral military action by the President, reinforcing the balance of power between branches of government. Therefore, recognizing both the Senate and House's roles in monitoring and limiting military engagement emphasizes the importance of legislative oversight in matters of foreign policy and military action.
