"On the other hand, we lost the war - not because we were out-fought, but because we were out-PSYOPed. Our national will to victory was attacked more effectively than we attacked that of the North Vietnamese and Viet Cong, and perception of this fact encouraged the enemy to hang on until the United States finally broke and ran for home. So our PSYOP failed. It failed not because its principles were unsound, but rather because it was outmatched by the PSYOP of the enemy."
