Hitler planning invasions of Britain and Russia at the same time. Madness.
And that's not all.
They are also, in the summer of 1940, considering another invasion -- which would have been relatively easy, and might even have won the war: Gibraltar.
At the time of his Nuremberg trial, Hermann Goering said Hitler's failure to take Gibraltar was the biggest mistake of the war.
Closing off Gibraltar to the British would have made Rommel's march to the middle east oil fields a cake walk.
And German control of the middle east would have changed strategic equations in the Soviet Union.
Now, everyone knows that Spanish dictator Franco dissuaded Hitler from taking Gibraltar.
But how many know who it was pulling Franco's strings, and why?
