OT Debate: If you were karl Donitz ....

[Hartmann]

First of all , in the battle of britain , correct the mistake of bombing london and continues with the destruction of air bases ,aircraft factories and ports.
this was the key factor of the german defeat with england.
With air superiority the british warships can be wiped out by planes, like the in the pacific war, where the Aircraft power against warships was decissive.

Build heavy bombers with a long range fighters scorts, and convert british factories in rubble

Concentrate all boats in the Western Appraoches of brittain, nor med or other scenarios.

Early development of snorkel and XXI boat

Be more careful with Enigma decoding system, and asumes it as probably decoded.
more changes in codes.

Finally, not related with doenitz but yes with hitler:

Not crush the british army in dunkerque.

Delay of guderian in reach moscow before winter 41 by hitler orders.

The stalingrad battle, where tank crews were used as an infantery troops in the city , the crazy fanatism in take a city with the stalin name at all costs and the lost of the whole 6th army.

After winter of 1942 ,the turning point, the war was lost anyway.
