The Czechoslovakians were appalled by the colony of Munich. They were not invited to the conference and felt betrayed by the British and French governments. Many Czechs and Slovaks describe the Munich agreement as a Munich diktat (Czech: Mnichovska diktéta); in Slovak: Mnechovska diktét). The phrase “Munich betrayal” (Czech: Mnichovska zrada; In Slovak: Mnechovska zrada) is also used because Czechoslovakia`s military alliance with France proved useless. This is also reflected in the fact that the French government, in particular, had considered that Czechoslovakia would be held responsible for any European war that would result if the Czechoslovak Republic defended itself by force against German abuses. In 1938, the Soviet Union was allied with France and Czechoslovakia. In September 1939, the Soviets were in every respect a fighter with Nazi Germany, due to Stalin`s fears that a second Munich agreement with the Soviet Union would replace Czechoslovakia. Thus, the agreement indirectly contributed to the outbreak of war in 1939.  Meanwhile, the British government has asked Benea to request a mediator. As he did not want to sever his government`s relations with Western Europe, the heirs reluctantly agreed.
The British appointed Lord Runciman, the former Liberal cabinet minister, who arrived in Prague on 3 August to convince Benes to accept an acceptable plan for the Sudeten Germans.  On 20 July, Bonnet informed the Czechoslovakian ambassador in Paris that France, while publicly declaring its support for the Czechoslovakian negotiations, was not prepared to go to war on the Sudetenland.  In August, the German press was full of stories of Czechoslovakian atrocities against the Sudeten Germans, with the intention of forcing the West to put pressure on the Czechoslovakians to make concessions.  Hitler hoped that the Czechoslovaks would refuse and that the West would feel morally justified in abandoning the Czechoslovaks to their fate.  In August, Germany sent 750,000 troops along the border with Czechoslovakia, officially as part of military maneuvers.   On September 4 or 5, Erbe presented the fourth plan, which met almost all of the requirements of the agreement. The Sudeten Germans were invited by Hitler to the prairies to avoid compromise, and the SdP organized demonstrations which, on 7 September, provoked a police operation in Ostrava, during which two of its deputies were arrested.  The Sudeten Germans used the incident and the false allegations of other atrocities as a pretext to interrupt further negotiations.   The New York Times headline on the Munich Accord was”Hitler receives less than his Sudeten claims” and reports that a “joyful crowd” had applauded Daladier on his return to France and that Chamberlain had been “savagely applauded” upon his return to the United Kingdom.  (8) Within four weeks of the date of this agreement, the Czechoslovakian government will release from its military and police forces all Sudeten Germans who wish to be released and the Czechoslovak government will release within the same period the prisoners of the Sudetenland who will serve prison sentences for political offences.
