“Gentlemen can never too often [be] requested to recollect the Debates in Congress in the Years 1775 and 1776, when the Treaty with France was first in Contemplation. [...]
It was then said, there is a Balance of Power in Europe. [...] It may be disturbed for a time, by the accidental Removal of a Weight from one Scale to the other; but there will be a continual Effort to restore the Equilibrium. [...]
If We give exclusive priviledges in Trade, or form perpetual Alliances offensive and defensive with the Powers in one Scale, we infallibly make enemies of those in the other. Congress adopted these Principles and this System in its purity.”
~ John Adams to James Warren, March 20, 1783, in Hutson, 13
