According to James Corum, while the popular view of the attack was a terror bombing aimed at the town, in reality the intended target was the bridge and roads. The issue was that pinpoint bombing was not possible at the time of the attack. Most of the bombers used by the Luftwaffe in Spain did not possess adequate targeting gear and thus the Condor Legion's preferred solution was to carpet the area with bombs to ensure the targets would be hit. Corum also argues against the view that there was a psychological element to the attack, stating that Richtofen seemed unaware of the significance of Guernica to the Basques and his diary indicates he only cared that the attack had been able to shut down logistics in the town. The Nationalists also didn't destroy the Basque parliament building or the Holy Oak, both of which had great cultural significance to the Basque and would have been excellent targets if the raid was meant solely to be a psychological warfare attack. Corum also argues that the attack on the town did not differ in style from the types of attacks the Allies conducted during WW2 and the Condor Legion regarded the attack as a routine tactical operation.
