It is the 28th June 1940. You are Herman Goering and a clearly shaken officer arrives to inform you of Hitler's assassination (a Polish officer had guessed correctly that Hitler that would visit Paris and had even guessed which buildings would interest the former would be architect). What would you do? Clearly attacking Britain by air, preparing to invade, a submarine and surface raider campaign, several Mediterranean projects and invading the USSR will all have advocates.
This seemed seasonally appropriate as many of us will have put on weight after eating too many mince pies. However, this thread is inspired by the many “You are Adolf Hitler” threads but attempts to focus only on Germany's strategic problem in 1940-41. It also avoids the problem that one could not be Adolf Hitler and still be willing to act benevolently towards the citizens of the USSR. Goering was clearly implicated in the Holocaust but neither it nor Eastern Lebensraum seemed central to Goering's ideology as shown by his “I decide who is a Jew”. It may be much easier to adapt your policy in the East if your first priority is looting the Hermitage.
I will try to give my own preference below which is not too different from what Germany actually attempted. I simply try (almost) everything!
Firstly preparations for invasion are much smaller and are simply designed to discourage Britain from releasing forces to defend elsewhere. The air attacks are also on a smaller scale than OTL and are almost exclusively aimed at the Royal Navy, Channel convoys and British ports. This has the advantage that most combats will occur over water and the attacks might sink more RN ships than OTL. From the RN's point of view, attacks from Plymouth to Harwich might seem an obvious precursor of an invasion.
Secondly we make the most rapid possible start of a Mediterranean campaign. This has been discussed many times, for example,
http://forum.axishistory.com/viewtopic.php?f=11&t=146796&p=1272610#p1272610 and the problems are agreed to have been diplomatic. Goering might have an advantage over Hitler as he could convincingly ask Mussolini for advice, admitting that he could not invade England and pointing out the many logistic problems of a Mediterranean strategy (see
https://www.alternatehistory.com/discussion/showthread.php?t=110306&page=2).
Thirdly, I would prepare to attack the USSR in 1941. The change from OTL in the management of the German economy would be that from July 1940, I would aim for the maximum possible production of aircraft, tanks and guns in 1941 rather than continuing the construction of factories that could start production in the second half of 1942 or later. I would also try to plan for operations deep in Russia by building more half tracks and trucks with good off road capability. Naturally, I would insist that the lessons of the campaign in France such as the need for tanks to carry guns capable of defeating 60 mm of armour on French Somua S35s and Char-B1s or 78 mm on British Matildas are learnt. I would also prepare to recruit as many enemies of Stalin as possible from the citizens of the USSR. The problem of feeding the cities and prisoners at the same time as the German armies is obviously difficult but soluble over 1941-42 at a cost of running down German supplies. Thus we distribute the collective farms immediately and blame shortages on Soviet sabotage (showing convincing film of Soviet scorched earth tactics with commentary in all the required languages).
For the possible continuation of the war with the Anglo-American powers, I would aim for qualitative improvements in the Luftwaffe for 1943-44 by ensuring that scientists and engineers are not conscripted and giving research high priority. I would abandon the Army's A4 (V2) programme and concentrate on jet aircraft, radar, improved piston engines (Oh dear! Synthetic oil plants are needed to produce high octane fuels), aircraft launched rockets and, as they are cheap, the V1 flying bombs. I would also become paranoid about coding machines and, as a quick fix, find resources to produce many many rotors with multiple (not factors of 26) notches for each machine and also use something like the Navy's enciphering of indicators in other services (alas I somehow doubt that the last few ideas would have sprung unaided into Herman's mind).
Alternative ideas anyone?
