You meet Hitler in Cologne and try to appease him by saying that you accept German annexation of Sudentenland.

Hitler says this is not enough. Hitler claims that the Czechoslovakian government had killed Germans. During the meeting, an aide comes in with "information" that more Germans are killed in Czechoslovakia. Hitler vows to avenge them all. 

Hitler tells you that he wants Czechoslovakia to be dissolved and its territory distributed to Germany, Poland and Hungary. 

Bang on the table and demand Hitler to stop his nonsense or you will order British troops to enter Czechoslovakia

Try to stall for time
