The first few months of 1939 were a time when the British government felt quite happy, which they had not seen for a long time. They believe that due to the accelerated rearmament of the country, the rearmament plan of the United States and the economic difficulties of Germany, the danger is decreasing day by day. At that time, the British government even prepared to hold a new disarmament conference, thinking that the world was about to enter a "golden age." At this time, the German Nazis were cultivating an independence movement in Czechoslovakia, which led to the division of Czechoslovakia. On March 12, after their leader Father Desso visited Hitler in Berlin, the Slovaks officially declared their independence. Later, the Germans entered and occupied the country as a protectorate.
