Even though no pre-war air forces had the means to accomplish what Douhet theorized, many American, British and German airmen paid at least lip service to this now discredited theory. As far as I can tell, Bomber Command always visualized bombing German cities and vice versa, even though their political leader didn't always agree. British civilians were issued gas masks on the idea that gas weapons would be part of the mix-it could have been worse. I have to generally agree with TiredOldSoldier's last paragraph but I think the reason for the continued and unnecessary city bombing in 1945 was that the British and American bomber barons had promised that their air attacks would win the war. They didn't, and I believe the British and American bomber leaders were desperately trying to make good on their promises and protect their services in the post-war era. At no time has any country called a war quits due to bombing alone. Instead of just saying, "Well, our bombers have done good things, but we're afraid that Douhet's theory was false.", they never questioned their basic operating principle.
