13.3 Presidential power in national security and emergencies

Presidential powers in national security and emergencies are rooted in the Constitution, which names the President as Commander-in-Chief. This role grants broad authority over the military, allowing for swift action in crises and shaping national security policy.

The National Emergencies Act and War Powers Resolution aim to balance presidential authority with congressional oversight. While these laws set limits, presidents have often pushed boundaries, leading to ongoing debates and landmark Supreme Court cases that shape the scope of executive power.
