Studies have shown that the Allied strategic bombing had neglible little effect on the German war effort, only seriously impacting it when transportation facilities (rail junctions, etc.) were put out of commission, thus preventing raw materials and components from reaching the relevant factories.
After the war it became clear that strategic bombing could have ended the war much earlier had power generation facilities been the priority target (no electricity, no production), but the strategic bombers weren't smart enough to figure that out.
