Remember this is the guy who with his 'jaw jaw not war war' kept the nazis busy While we built our airfields and our Spitfire's and Hurricanes, he allowed the development of various technical military advances ie Radar and sonar and most importantly approved the building of an integrated air defenses network that proved itself, exactly at the right moment in world history.
That 'guy' was an appeaser par excellence. Ask the Czechs what they think about Chamberlain.
And you might dwell on Sir Winston Churchill's wiser words when he said "You have chosen dishonor over war. And you shall have both."
