When I say international entanglements, I am talking about the UN, NATO, NAFTA, G8, etc. Avoiding international entanglements in no way means not defending ourselves from foreign aggression.
No, our founding fathers said nothing about the UN, NATO, NAFTA, G8, etc. :)
But they were in favor on international treaties, and alliances when they were in our interest. And that is what the UN, NATO, NAFTA, G8, etc. are.
