I'm afraid Dr. Sowell has his wars and generals mixed up.
The current leaders of the Republican Party in no way resemble George Washington. They're much closer in spirit and temperament to this guy.
General McClellan
(1826-1885)
George McClellan was the greatest Union general during the Civil War. At least he could have been and should have been.
[...]
McClellan was very cautious always overestimating the size of the enemy. He always believed he was greatly outnumbered and was constantly seeking more and more reinforcements.
He was afraid to attack. He did not want to put his men in harms way and wanted to keep them safe, and they in turn loved him for this, but that is no way to ever win a war.
[...]
McClellan was attacked several times by General Robert E. Lee and the Army of Northern Virginia, which was much smaller in size than McClellans army during the Seven Days Battles.
Although never being actually defeated in these battles McClellan nevertheless retreated.
You give the GOPe leadership too much credit. George McClellan, at least, finally won at the pivotal Battle of Gettysburg.
I think a more apt comparison would be a Marshall Philippe Petain or even a Vidkun Quisling.
“Although never being actually defeated in these battles McClellan nevertheless retreated.”
The strategic objective is therefore your enemy’s mind. If he believes himself defeated, he is. With apologies to Sun Tzu...
