Final answer:
British Prime Minister Neville Chamberlain was excited about the Munich Agreement because he believed it would prevent a war with Germany. Other nations, such as Czechoslovakia, felt betrayed and feared further aggression from Germany.
Step-by-step explanation:
The Munich Agreement, signed in September 1938, was seen by British Prime Minister Neville Chamberlain as a diplomatic victory and a means to avoid war. Chamberlain believed that by giving in to Hitler's demands to annex the Sudetenland, he had secured peace with Germany.
However, other nations, such as Czechoslovakia, were not invited to the conference and were unhappy with the agreement. They felt betrayed by the Western powers' appeasement of Hitler and feared further aggression from Germany. This eventually proved true when Hitler went on to forcibly annex the rest of Czechoslovakia in 1939.
