A standing military force, with an overgrown Executive will not long be safe companions to liberty. The means of defence agst. foreign danger, have been always the instruments of tyranny at home. Among the Romans it was a standing maxim to excite a war, whenever a revolt was apprehended. Throughout all Europe, the armies kept up under the pretext of defending, have enslaved the people.
~ James Madison, Constitutional Convention, [June 29, 1787]
