Federalist No. 4
Federalist No. 4, authored by John Jay under the pen name Publius, is the fourth of 85 essays. Titled "The Same Subject Continued: Concerning Dangers from Foreign Force and Influence", Jay discusses foreign influence, just and unjust wars, and peace through strength with the creation of one large military force.
It was published on November 7, 1787.
Jay's thoughts in this paper focus on the merit and advantages of having one singular military for the states instead of thirteen militaries which could potentially be fraught with inferiority in various areas. He points out that "a good national government as necessary to put and keep them in SUCH A SITUATION as, instead of INVITING war, will tend to repress and discourage it." He worries that a military divided between thirteen states will complicate trade with various nations, such as China and India, and that their unified military forces ought to be met with a more powerful converse force. He makes similar arguments in regard to France and Britain, and points out that Spain was making aggressive moves along the Mississippi River.
This unification, in his view, is the best way to ensure peace.
