@yamamato456:
Well actually the battle of britain itself was not necassarily a German mistake. The way the battle of britain was fought was a mistake. In the beginning of the battle the Germans were smart to only target the British airforce. However, the air battle was lasting longer than Hitler wanted… so he decided he would bomb London instead. All of the german generals thought this was a huge mistake and wanted to keep attacking the airforce. In fact on the day that they started targetting london there were only 14 operational planes in the whole UK. If the German generals would have had their way the Germans would have won the battle of britain.
Even assuming Germany “wins” the air war, they never win the battle of Britain. Britain never gets successfully invaded, Germany just doesnt have the operational power to do so.
The mistake was in attacking Britain, rather than the Med. Taking Egypt (and gaining access to Iran/Iraq oil) and depriving UK of supplies was the only way to “win” (which eventually would not have worked as the USA would eventually enter the war and supply Britain with whatever was needed).
Had the med been conquered and become an axis lake, you could delay Torch till 44. Perhaps egypt is never retaken until 45. Which would give Germany time to mass produce its "super-weapons). This also assumes the blunders on the eastern front are also ignored.
