Why did Churchhill believe that a focus on the Mediterranean instead of the French northern coast would best deal with the expansion of the Soviet union?

I am watching the Battlefield series and I’m currently on the episode: “The Battle of Normandy” and this statement is made. It is not expounded upon. Why did Churchill believe that the invasion of Italy was more important to dealing with the future of the Soviet union?
