Why did Hitler scrap his plans to invade Britain?

Because the Luftwaffe were unable to destroy the British Air Force during the Battle of Britain and without mastery of the air, you can't commit ground forces.

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.
