Why didn't Hitler invade Britain in 1940 or 1941?

Tler believed that for the operation to be successful, Germany would need complete air supremacy over the battlefield. With the failure of the Luftwaffe to disable the Royal Air Force during the Battle of Britain, tler was forced to cancel the operation. Operation Sealion (the operation name for the planned invasion of Britain), was canceled on the 17th of September 1940.

However, troops assigned to the operation were not released for other duties until February 1942 (after the invasion of the Soviet Union). Despite the general superiority in training, equipment and number of German troops on the ground in 1940, the general consensus is that British superiority at Sea and in the air would have doomed an invasion force to a forced withdraw or isolation and surrender.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
