You are Neville Chamberlain, the Prime Minister of Great Britain.
Hitler has accused the Czechoslovakian government of ill-treating the Germans in Sudetenland (the northern, southern, and western areas of former Czechoslovakia which were inhabited primarily by Sudeten Germans).
According to Secret Service sources, Germany is going to attack Czechoslovakia on the pretext of liberating the Germans in the Sudetenland. This invasion is scheduled to take place on 25 September.
Such an invasion would be disasterous for Europe. You still have traumatic memories of World War I.
