The Constitution applies to the federal government—not Americans, citizens, or "people."
The words of the Constitution tells the federal government what it is allowed to do, and in some places it explains how to do it.
The Bill of Rights tells the federal government what it is not allowed to do.
Get it right.
“The power to declare war, including the power of judging the causes of war, is fully and exclusively vested in the legislature.” ~ James Madison, Father of the Constitution
