Early in WW2 USAAF strategic planners looked at the German electrical grid as a prime target, but decided that it was probably too dispersed to be a knock out blow worthy target in the end, which post-war examination of the German economy showed to be horribly wrong; they concluded had they gone after the German electrical grid in 1943 they could have ended the war by mid-1944 due to the total collapse of German production that would result. What if they did? What effect would a total collapse of German industrial production have had by June 1944? Would it cause an immediate surrender or would Hitler try and struggle on? Would the resistance then have enough support to overthrow Hitler and make peace? I'm assuming that from August 1943 on instead of going after ball bearings or other targets the USAAF opts to hit electrical targets, so there is a large degrading of German production from that point on until in 1944 it totally falls apart.
How would that impact the post-war situation if the Germans surrender at least 12 months early?
