Assuming I’m still Evil Hitler (hey the OP Godwin’d and called me Hitler in the first post)
No Holocaust. I might need the Marge Schott vote later.
Shoot Adm Canaris.
Push hard to capture as many prisoners as possible at Dunkirk
Replace a rotor every week on Enigma. Ignore bombing London, bomb Bletchley Park. Daily.
Blockade UK from the air and concentrate Wolf Packs to destroy shipping and Royal Navy around UK. Operation Sea Lion becomes the priority. Barbarossa has to wait at least a year if not two. Stalin is busy becoming strong in the meantime.
Do not attack Soviet Union unless and until UK surrenders unconditionally. When attacking USSR, do not kill civilians, but co-opt them as they hate Stalin.
When Japan attacks Pearl Harbor, do not declare war. In fact, publicly condemn as an act of aggression on the “peaceful” US and break off Axis Pact with Japan and insincerely offer to help the US in order to undermine Roosevelt.
See all movies in private screenings. Send double to Inglorious Basterds premiere, make sure only incompetent officers attend.
Have Himmler assassinated, same with Heydrich. Not because they are evil, but because they are threats to my power. No need to mess with Stauffenberg assassination ring because they only did it because of losses to the army.
Use the 262 fighters as fighters, and not bombers. Make lots more of them. Drop the Comet rocket fighter program. Really cool, but not effective. Same with V1 and V2 programs. Not effective militarily. Develop 4 engine bomber, computers, radar and proximity fuse.
Because I’m evil, execute Dietrich Boenhoeffer in the 1930s. Don’t get addicted to drugs, don’t let Goering get addicted to drugs and don’t give him so many jobs.
Make sure that Doernitz has at least 400 submarines before starting war, rather than less than the 300 he said were necessary. This is essential to winning the Battle of the Atlantic.
USSR. Only when UK has surrendered and Egypt also secured. Take over Turkey first. As mentioned earlier, no mass killings. Have enough cold weather gear for every troop. Co-opt populace by providing massive amounts of food aid and use lots of anti commie propaganda. Do not attack cities, but rather occupy the rail hubs around Leningrad, Stalingrad and Moscow. With the Turkish flank already held, without the UK and Africa to drain forces and distract, and with oil secured, USSR is probably conquerable.
Number one evil thingy is to change enigma with one new rotor every week. Also communicate with enigma and a code within enigma. Make sure that everyone on general staff assumes that enigma is limited.
