Answer:
Allowing Hitler to expand German territory unchecked
Explanation:
Hitler’s expansionist aims became clear in 1936 when his forces entered the Rhineland. Two years later, in March 1938, he annexed Austria.
Appeasement was popular for several reasons. Chamberlain - and the British people - were desperate to avoid the slaughter of another world war. Britain was overstretched policing its empire and could not afford major rearmament. Its main ally, France, was seriously weakened and, unlike in the First World War, Commonwealth support was not a certainty. Many Britons also sympathised with Germany, which they felt had been treated unfairly following its defeat in 1918.
However, Winston Churchill, then estranged from government and one of the few to oppose appeasement of Hitler, described it as ‘an unmitigated disaster’.
