It is always a bad thing when political matters are allowed to affect . . . the planning of operations.Field Marshal Erwin Rommel - 1943 C.E
The only way I know this is that David Weber uses this quote in The Shadow of Saganami (The Saganami Island) [Oops... not Shadow of S., but Field of Dishonor (Honor Harrington) - not sure how I messed that up!]
Rommel was speaking from the perspective of one who lost a war.
Is this is what is happening in Afghanistan?
