In order to save his troops from certain annihilation at Dunkirk, Churchill lied to Hitler about entering into a peace agreement. If Hitler had not taken the bait, and it had of come down to it, Churchill had anticipated that he might have to settle with Hitler to keep him out of Britain, and he had given some thought to the best deal he could strike in that case.

Hitler was known to admire the British, having spent some time with his cousin in Liverpool before WWI.

In the event, Hitler took the bait, and the ruse was later used to nab Hess.

Ignorant of history, your writer misses the main point: Britain learned a lesson with Hitler, and has a very low tolerance for bullying thugs.
