The bomber will always get through was a phrase used by Stanley Baldwin in 1932, in the speech "A Fear for the Future" to the British Parliament. He and others believed that, regardless of air defences, sufficient bomber aircraft will survive to destroy cities.
Baldwin did not advocate total disarmament but believed that "great armaments lead inevitably to war". However he came to believe that, as he put it on 9 November 1932: "the time has now come to an end when Great Britain can proceed with unilateral disarmament". On 10 November 1932 Baldwin said:
I think it is well also for the man in the street to realise that there is no power on earth that can protect him from being bombed. Whatever people may tell him, the bomber will always get through, The only defence is in offence, which means that you have to kill more women and children more quickly than the enemy if you want to save yourselves...If the conscience of the young men should ever come to feel, with regard to this one instrument [bombing] that it is evil and should go, the thing will be done; but if they do not feel like that – well, as I say, the future is in their hands. But when the next war comes, and European civilisation is wiped out, as it will be, and by no force more than that force, then do not let them lay blame on the old men. Let them remember that they, principally, or they alone, are responsible for the terrors that have fallen upon the earth.
This speech was often used against Baldwin as allegedly demonstrating the futility of rearmament or disarmament, depending on the critic.
Many theorists, especially in Britain, imagined that a future war would be won entirely by the destruction of the enemy's military and industrial capability from the air. The Italian general Giulio Douhet, author of The Command of the Air, was a seminal theorist of this school of thought.H. G. Wells' pre-World War I novel The War in the Air concluded that aerial warfare could never be 'won' in such a manner as bombing, but in 1936 he depicted a war starting suddenly with devastating air attacks on "Everytown" in the film Things to Come. Likewise, Olaf Stapledon, in his 1930 novel Last and First Men depicts a very brief but devastating war in which fleets of bombers deliver huge payloads of poison gas to the cities of Europe, leaving most of the continent uninhabited. As late as 1939 Nevil Shute portrayed a war opening with a sudden air attack by bombers in his novel What Happened to the Corbetts.
