The correct answer is: "Non-intervention policy"
George Washington was adressing the issue on whether it was benefitial or not to establish alliances with foreign countries. Thomas Jefferson did it later as well, exactly in the same line as Washington, as it can be seen in this quotation: "Peace, commerce, and honest friendship with all nations-entangling alliances with none."
They exemplified like this the national point of view which had set the way of proceeding at the time. It was maintained from 1789 until the end of WWII. The only exception was the relationship of the US with Panama.
But after WWII the situation became the opposite, the US allied with half of the world and included them as part of the capitalist block, to confront the URSS and the communist system.
