Could Germany have built a proper heavy-bomber force and made Britain negotiate if the war continued without Soviet or American involvement?
Short answerOnly after an implausibly wide set of changes. Britain and Canada were producing bombers while Germany faced design, component, factory, crew, and fuel constraints.
NotesThe counterfactual requires many conditions to favour Germany even without Soviet or American entry into the war. Britain and Canada were already producing large numbers of bombers, while Germany pursued increasingly demanding designs. A German heavy-bomber force would require more factories, specialised components, trained crews, and fuel that was already scarce. British attacks on inputs such as ball bearings also pushed German aircraft production toward simpler designs. Negotiated peace through a late heavy-bomber build-up is therefore treated as possible only after an implausibly broad set of changes.
