The events of march 1939 ended the Munich fiction. As far as Adolf Hitler was concerned, he had liquidated Czechoslovakia, and he could proceed to deal with Poland. At the end of the inevitable world war, Czechoslovakia would be resurrected in its former shape and would resume its historical development where it had left off. In one way, the situation was easier. Czechoslovakia had been independent for twenty years; it did not have to prove to the United States or Britain or France its right to exist. The guarantee given to Poland contrasted with the betrayal of Czechoslovakia, and its irrelevance to the defence of that country in September 1939 was treated with cynicism and even with glee. The Anglo-French renunciation of Munich was the end of a chapter was for Britain and France as well as for Czechoslovakia. The United States had helped to give birth to Czechoslovakia both during and after the First World War.
