Once an enemy loses fear (and respect), a war is already over, before it's begun...
The term "war of attrition" implies one political cycle to one general and forever to another; ten thousand troops for one general and everyone to the other
"Westmoreland was convinced that the Vietnamese communists could be destroyed by fighting a war of attrition that, theoretically, would render the Vietnam People's Army unable to fight. His war strategy was marked by heavy use of artillery and airpower and repeated attempts to engage the communists in large-unit battles, and thereby exploit the US's vastly superior firepower and technology. However, the North Vietnamese Army (NVA) and the National Liberation Front of South Vietnam (NLF) were able to dictate the pace of attrition to fit their own goals: by continuing to fight a guerrilla war"
"Westmoreland criticized the battlefield prowess of his direct opponent, North Vietnamese general Vo Nguyen Giap. "Of course, he was a formidable adversary. Let me also say that Giap was trained in small-unit, guerrilla tactics, but he persisted in waging a big-unit war with terrible losses to his own men. By his own admission, by early 1969, I think, he had lost, what, a half million soldiers? Now such a disregard for human life may make a formidable adversary, but it does not make a military genius. An American commander losing men like that would hardly have lasted more than a few weeks. The Oriental doesn't put the same high price on life as does a Westerner. We value life and human dignity. They don't care about life and human dignity."

Some people still get history on their History Channel. Other people just never learn.
