@ajsadauskas Actually that's not what happened. Chamberlain declared "peace in our time" to prevent public panic in March 1938; immediately afterwards—the day after his meeting with Hitler—he called an emergency Cabinet meeting to set up the UK's biggest-ever rearmament program because he knew war was inevitable.
He didn't resign as PM until the catastrophic French collapse in summer 1940: he was an okay leader, pilloried long after the fact for a single misinterpreted statement.
