Corum continues: General Walther Wever compiled a doctrine known as "The Conduct of the Aerial War". This document, which the "Luftwaffe" adopted, rejected Giulio Douhet's theory of terror bombing. Terror bombing was deemed to be "counter-productive", increasing rather than destroying the enemy's will to resist. Such bombing campaigns were regarded as diversion from the "Luftwaffe's" main operations; destruction of the enemy armed forces. The bombings of Guernica, Rotterdam and Warsaw were tactical missions in support of military operations and were not intended as strategic terror attacks.
