My apologies if this question has been asked before but I looked through the FAQ's and searched for relevant keywords and was surprised to see that it hadn't, to the best of my knowledge.
I will try and make my question as clear as possible. As an Englishman, most people here commonly remember Churchill as the Prime Minister that "Won Britain the War". Is this view historically accurate, or is his impact overstated?
I originally titled my question "How important was Winston Churchill in Britain and the Allies being victorious in WWII" but I thought I would add my definition of victorious to the title. If there were other factors which you consider more important, please do comment on these in your answers.
Thank you all, and thanks to everyone who asks and answers questions on this brilliant subreddit.
Boris Johnson argues 'very' in his book "The Churchill Factor", given that Churchill saw the threat the Nazis posed early, and argued for fighting when many of his contemporaries were seriously considering surrender in the face of overwhelming odds.
His greatest achievement was to offer perhaps the one leader of sufficient standing around whom all parties could rally in supporting the 1940 wartime coalition government, just after the Norway failure and as the far worse French debacle was abut to unfold, and then to face down the appeasers toward the end of May. His second was to embrace alliance with the USSR after the German invasion a year later: a lesser politician of the right might have been tempted by his anti-communism to take a different line.
He kept up the morale of the British people, and when you're being bombed and seeing your city flattened slowly, it is important to have good morale.
If the British people had pressured the government into surrender, the entire outcome of the war changes completely.
