How did France and Britain first respond to Germany and acirc and 128 and 153s expansion of territory?

France and Britain initially responded to Germany's expansion of territory with a policy of appeasement, hoping to avoid conflict by conceding to some of Germany's demands. However, as Germany continued its aggressive actions, particularly with the invasion of Poland in 1939, both nations shifted to a more confrontational stance, ultimately declaring war on Germany. Their early attempts at diplomacy and compromise failed to curb Hitler's ambitions, leading to the outbreak of World War II.
