Who was left to defend itself alone due to the policy of appeasement?

Czechoslovakia was left to defend itself alone due to the policy of appeasement adopted by Western powers in the lead-up to World War II. As they sought to avoid conflict, Britain and France allowed Nazi Germany to annex the Sudetenland in 1938 without military intervention. This decision weakened Czechoslovakia's position and ultimately led to its occupation by German forces in 1939.
