Answer
Attrition, the strategy adopted by General Westmoreland against the Viet Cong, involved inflicting heavy casualties on the enemy to deplete their manpower and resources. This approach aimed to gradually weaken the Viet Cong's fighting strength and morale, forcing them to negotiate or surrender. Westmoreland believed that by inflicting significant losses, the Viet Cong would eventually be unable to sustain their insurgency.
