Nice isolationist philosophy.
But the Arab world came to us on September 11, 2001. And with Afghanistan and Iraq, we took it to the Arab world.
Nice isolationist philosophy.
Especially since in Adams' day we had Britain and the Royal Navy to search out the monsters.
But the Pax Britannica is long over.
The alternative, alas, is Pax Americana or no "pax" at all.
Or worse yet: Pax Sinica.
This philosophy, which you call "isolationist" (I prefer the terms "non-interventionism" or "armed neutrality") is the foreign policy application of the American principle of limited government. George Washington, and every other major political leader of this country at the time of the founding, believed that we should avoid entangling alliances and imperial wars.
It is the new ideology of "pax americana" and "benevolent world hegemony" which is new and alien to America. I would go so far as to consider these ideologies, and there adherents, to be un-American.
