“The bomber will always pass through” (“TheWill Always get through”) is a term used by in 1932, in the speech “A fear for the future” (A Fear for the Future) to Columbia1 Parliament. The argument was that regardless of air defense, the bombers pass sufficient to destroy cities2.
It was not hyperbole, this time, the bombers were slightly better than the hunters with their multiple motors, a successful interception and therefore required careful planning so that the hunters are in the right place to deal with bombers. Beforeand the invention of radar detection systems were visual or auditory, which gave only a few minutes notice, enough to organize an interception. This balance of forces meant that the bombs were dropped and there was little to do to prevent it. For the UK, the response has been to focus on the production of bombers, seen first as a deterrent.
Many theorists, especially in Britain, had imagined a future war would be won only by the destruction of the military and industrial capacity of the enemy from the air. The Italian General Giulio Douhet was the theoretician behind this school pensée3. The novel Thein the air (The in the Air) H. G. Wells, published before the First World War, concluded that the air war could never be won by bombing. The only soldier or politician in the world who might be at odds with the thinking of Baldwin was , head of Fighter Command of the RAF during the of England4.
The phrase was used again to refer to suicide bombing and the inability of law or security to stop someone who intends to blow some chose.
