Our losses... have reached and intolerable level.

Our losses have reached an intolerable level. The enemy air force played a decisive role in inflicting these high losses.

I accept responsibility for U-boat warfare from 1933 onward, and of the entire navy from 1943 on, but to make me responsible for what happened to Jews in Germany, or Russian soldiers on the east front it is so ridiculous all I can do is laugh.

The reason that the American Navy does so well in wartime, is that war is chaos, and the Americans practice chaos on a daily basis.
