Dönitz opposed Raeder's views that surface ships should be given priority in the "Kriegsmarine" during the war, but in 1935 Dönitz doubted U-boat suitability in a naval trade war on account of their slow speed. This phenomenal contrast with Dönitz's wartime policy is explained in the 1935 Anglo-German Naval Agreement. The accord was viewed by the navy with optimism, Dönitz included. He remarked, "Britain, in the circumstances, could not possibly be included in the number of potential enemies." The statement, made after June 1935, was uttered at a time when the naval staff were sure France and the Soviet Union were likely to be Germany's only enemies. Dönitz's statement was partially correct. Britain was not foreseen as an immediate enemy, but the navy still held onto a cadre of imperial officers, which along with its Nazi-instigated intake, understood war would be certain in the distant future, perhaps not until the mid-1940s.
