Hitler did have reasonable issues as to the Sudeten Germans and Danzig, but instead of engaging in diplomacy, even at knifepoint, he went postal.
Chamberlain was not a coward or a pu$$y. He followed the political line that was shared by the King, Lord Fairfax, and the upper classes of which Lord Hamilton, the target of Hess' mission, were toeing.
I admit that I bought into this perversion of history and it is purely ignorant. The only more egregious perversions are by the Churchill haters, who to this day rewrite history to slander him for whatever reason!
The statement was made to mean that had Hitler have attacked Britain in 1938, he would have had an immediate success. Churchill was kind enough to deliver a eulogy a few days after Chamberlain's death in 1940. He was a broken man because of the perfidy of Hitler.
Excuse the ramble and I shall have to do more reading of Hess and his flight.
