The US Constitution authorizes Congress to issue Letters of Marque (to private citizens).
To implement a Letter of Marque, the designated citizen would need to own one or more BATTLESHIPS.

Game set & match. (shudders: were any Letters of Marque issued to companies? Can you imagine what Google — worse yet, the Clinton Global Initiative and Massage Parlour — would do with one?)
