Commander In Chief

Clyde Wilson nails it:
Constitutionally, the President is not the commander-in-chief of the country. He is not even the commander-in-chief of the government. He is merely the commander-in-chief (operations director) of the armed forces. And, constitutionally, the armed forces exist only as created by the Congress which must re-authorize their funding every two years. [emphasis added]

The president's powers as commander in chief of the armed forces depend wholly on Congress's power to create and fund them. The President has very little power aside from enforcing Congress's will. He has no inherent authority as "commander in chief" to deploy federal agents to spy on or nab individuals without search or arrest warrants. Those who assert that the President has this power are advocates for dictatorship. They are more dangerous to the American people than any alleged foreign threat.
