According to Churchill, Britain’s position changed drastically as the war had started.
Explanation:
As the World War II began, Britain started losing its power. The Germans were already advancing towards Britain. Britain had already lost a lot of its empires. The United States of America was emerging to be a greater power and most of the policies and plans of Britain was failing.
So as the war began, Churchill was of the opinion that Britain was no longer powerful and that its position was falling leading to the growth of unpopularity and a severe crisis.
