Germany stated that Austria`s integration into the empire led to borders with Czechoslovakia, which posed a great threat to German security, and that this allowed The Western powers to be locked up in a German way.  Although the British and French were satisfied, a British diplomat in Berlin claimed that he had been informed by a member of Hitler`s entourage that shortly after the meeting with Chamberlain, Hitler had said angrily: “Gentlemen, this was my first international conference, and I can assure you that this will be my last.”  On another occasion, he had been heard by Chamberlain: “If this stupid old man ever intervenes again with his umbrella, I will shoot him and jump on his stomach in front of the photographers.”    In one of his public speeches after Munich, Hitler declared, “Thank God we have no politicians in this country.”    Reactions to the treaty in Germany have been very negative. There were demonstrations in the German Reichstag and in the street. It is not difficult to understand why the Germans were outraged. Germany has lost 10% of its country, all its overseas colonies, 12.5% of its population, 16% of its coal and 48% of its iron industry. There were also the humiliating conditions that led Germany to take responsibility for the war, to limit its armed forces and to pay for reparations. This is partly due to the fact that American politics was deeply divided at the time. President Wilson led the Democratic Party. However, his rivals in the Republican Party dominated the U.S.
Congress. They took advantage of the treaty to criticize Wilson. Wilson has to take some of it, because he has made little effort to consult Republicans on the treaty. The Americans were also concerned about the Wilson League of Nations project. They were concerned that membership in the League would lead the United States into international disputes that were not their concern. In the end, Congress rejected the Treaty of Versaille and the League of Nations. On May 20, Hitler presented his generals with a draft plan of attack for Czechoslovakia, codenamed Operation Green.  He insisted that Czechoslovakia should not be “dismantled” militarily, without “provocation,” “particularly favourable opportunity” or “appropriate political justification.”  On May 28, Hitler convened a meeting of his department heads, ordered the acceleration of submarine construction and advanced the construction of his new battleships Bismarck and Tirpitz in the spring of 1940.
He asked to accelerate the increase in the firepower of the battleships Scharnhorst and Gneisenau.  Hitler realized that this would still not be enough for a full maritime war with Britain, Hitler hoped it would be a sufficient deterrent.  Ten days later, Hitler signed a secret line of war against Czechoslovakia, which was to begin no later than October 1.  Meanwhile, a new Czechoslovakian cabinet was set up under the head of General Jan Syrova and, on 23 September, a general mobilization decree was adopted with great enthusiasm by public opinion – in 24 hours, one million men joined the army to defend the country.
