When we wrote the Constitution, the intention was to give the commander in chief the authority how to use the forces when you authorize him to be able to use the forces.
I thought they know that I was the Commander in Chief, not that I know that I am the Commander in Chief, and they should behave; know how to behave to the Commander in Chief.
I am not a Starfleet commander, or T.J. Hooker. I don't live on Starship NCC-1701, or own a phaser. And I don't know anybody named Bones, Sulu, or Spock.
