I'm currently rereading "Gods and Generals", Jeff Shaara's account of the years before the battle of Gettysburg portrayed in his fathers book "Killer Angels".
Shaara describes an incident where former US Army Lt Col Robert E. Lee has refused command of the Federal Army, resigned his commission, and is on his way to accept command of the Va State forces.
As he walks to the Governors office he pauses to contemplate a statue of George Washington and asks himself, "What changed ?
Why didn't it work ?"
He goes on to consider the Great men, Adams, Madison, Washington, Jefferson .
Reading that it dawned on me exactly what went wrong .
The Constitution was written for men of honor , men of integrity, reason, and character.
The flaw was that we got everything but, instead of men of integrity, reason, and character, we got politicians and nothing written by the first sort can ever protect against the second sort.
