This is where we are headed: An impulsive and bellicose president empowered to use force on his own authority advised by the advocates of aggressive war with a covert arm headed by a practitioner of torture.
This is precisely what the founders of the country sought to protect against by giving Congress the power to declare war. James Madison noted that the power to declare war is “fully and exclusively vested” in the Congress because the “executive is the department of power most distinguished by its propensity to war: hence it is the practice of all states, in proportion as they are free, to disarm this propensity of its influence.”

Hmmm ... Madison was a slave owner, so maybe we should just ignore him, tear down his statues, and burn his writings. We don't need no stinking constitution anyway.
