Which admirals won the confidence of wartime leaders?

Which senior naval officers were especially favored or trusted by Churchill, Roosevelt, Japan's emperor, and Stalin?

The examples are Keyes and Cunningham for Churchill, Nimitz and a working respect for King under Roosevelt, Yonai in Japan, and more tentatively Gorshkov for Stalin.

Churchill is associated particularly with Roger Keyes and Andrew Cunningham. Franklin Roosevelt favored Chester Nimitz and appears to have held a functional respect for Ernest King despite King's difficult reputation. Mitsumasa Yonai is offered as a likely Japanese example, while Sergei Gorshkov for Stalin is more tentative. The comparison separates genuine trust from formal command authority across very different political systems.
