How/Why did the Germans go to such lengths to destroy Britain?

The Germans wanted to defeat Britian so they could take over Europe. Also to take over Suez Canal. Germany would track British ships and disguis themselves to be from the Britian navy. This leading to defeating Britian's navy. Britian then decided to call Japan for help. So Japan seized Germany's resources. This made Germany mad. They wanted to herass Britians, but they did not have enough troops. So Germany brought in Turkey to help fight.
