An affirmative-action politically-correct racist-voting General purports to tell others to be politically correct. Powell is typical of the present day product of West Point, Annapolis and the Air Force Academy who attain their position by being, above all, politically correct. Google the comments of current day and especially recently past chiefs of staff of the military and you will see that they are all P-C.
There was a G.W. Bush war against Iraq because Powell, unable to stand the sight of Muslim losses, advised G.H.W. Bush to stop at the Iraq border instead of taking care of the Hussein problem. Powell believes that wars are for dragging to a draw, not for winning.
