I suggest you avoid reading President Washington’s Farewell Address. You will surely find it upsetting.

I think Washington’s advice is excellent.
He certainly earned the right to give it
after risking everything to lead a WAR against the British to win independence.
But freedom isn’t free is it?
That is the terrible ethic from which the evil neocons derive their wisdom.
Whether Washington or Jefferson or any array of American presidents— the continual vigilance and even use of force is necessary for the maintenance of liberty.
It is actually much easier to protect that force today than it was for Washington. The fact that the British came back in 1812 to trash Washington DC was emblematic of how necessary the use of force is.
