What would the Founding Fathers say?
If you are referring to Washington’s Farewell Address, it has been terribly misinterpreted. It is primarily concerned about the danger of secession not as a permanent admonition against foreign involvement.
That warning was directed to those wanting to join the French against the British for two reasons. First we had a military that was pitifully weak, so weak even the Indians were able to slaughter one of our armies not all that long before. Two the greater danger was that joining one side in the war would stimulate the forces in the South who already were threatening secession. This is what all the authors of the Address feared, first Madison, then Hamilton then Washington produced the document.
