Isoroku Yamamoto

I fear all we have done is to awaken a sleeping giant and fill him with a terrible resolve.

A military man can scarcely pride himself on having smitten a sleeping enemy; it is more a matter of shame, simply, for the one smitten.

In the first six to twelve months of a war with the United States and Great Britain I will run wild and win victory upon victory.

But then, if the war continues after that, I have no expectation of success.
