That's revisionist history 101 right there. Because he appeased Hitler, Hitler pushed again and again to eventually trigger world War 2. And the rest of what you said is nonsense. The RAF was crushed so any build up was just wasted aircraft and lives. It was Hitler's stupidity in switching from air bases and factories to bombing London that allowed the Brits at that time to rebuild and eventually win the battle of Britain. Prior to that the RAF was on its knees.
