Answer: Did nothing and appeased Hitler
Explanation:
Before the Allies finally took action against Germany when they invaded Poland in 1939, they generally followed a policy of appeasement for the German dictator.
The British Prime Minister, Neville Chamberlain was much in support of this policy more than his French allies and they did not want to act alone for fear of defeat so they went along with the policy of appeasement followed by the British who did not want to get involved in an expensive war.
