Appeasement.

Explanation:

Appeasement is a policy of avoiding conflict by granting concessions to an aggressive power.

As Britain's main ally, France, weakened, and Britain no longer had full support of the Commonwealth, Britain had no other option but to avoid the war at all costs. British Prime Minister Neville Chamberlain was forced to follow the policy of appeasement, now also known as the policy of weakness. As a result, Hitler was allowed to expand the German territory, facing no resistance. Churchill, on the other hand, insisted that Britain must go to war and should under no circumstances try to make peace with Hitler.
