After his success in integrating Austria into Germany in March 1938, Adolf Hitler looked greedy at Czechoslovakia, where about three million people were of German origin in the Sudetenland. In April, he discussed with Wilhelm Keitel, head of the Bundeswehr`s high command, the political and military aspects of „Case Green,“ the code name for the Sudetenland takeover project. A startling attack „from clear skies without reason or justification“ was rejected because the result would have been „a hostile opinion of the world that could lead to a critical situation.“ Decisive action would therefore take place only after a period of German political turmoil in Czechoslovakia, accompanied by diplomatic quarrels which, as they became more serious, would either constitute an excuse for the war themselves or the occasion for a lightning offensive after an „incident“ of German creation. In addition, there had been disturbing political activities in Czechoslovakia since October 1933, when Konrad Henlein founded the Sudeten German Home Front. On the 22nd.

Chamberlain had calculated that full acceptance of the German annexation of all sudetenland without cuts would force Hitler to accept the agreement.  When Hitler learned of this, he replied, „Does this mean that the Allies agree with Prague`s consent to the surrender of the Sudetenland to Germany?“ Chamberlain replied, „Exactly,“ to which Hitler replied with a whim, saying that the Allied offer was insufficient. He told Chamberlain that he wanted Czechoslovakia completely dissolved and its territories redistributed to Germany, Poland, and Hungary, and told Chamberlain to take it or leave it.  Chamberlain was shocked by this statement.
 Hitler went on to tell Chamberlain that since their last meeting on the 15th, the actions of Czechoslovakia, which Hitler claimed belonged to murders of Germans, had made the situation unbearable for Germany.  Later in the session, a pre-arranged deception was undertaken to influence Chamberlain and exert negative pressure: one of Hitler`s accomplices entered the room to inform Hitler that other Germans had been killed in Czechoslovakia, to which Hitler shouted in response, „I will avenge each of them.
