Those who have command of the arms in a country are masters of the state, and have it in their power to make what revolutions they please. [Thus,] there is no end to observations on the difference between the measures likely to be pursued by a minister backed by a standing army, and those of a court awed by the fear of an armed people.

Aristotle

"An Argument showing That a Standing Army is Inconsistent with a Free Government, and Absolutely Destructive to the Constitution of the English Monarchy."
