I'm not referring to the quote about the sleeping giant. As I mentioned, I'm far more interested in the first Yamamoto quote - "You cannot invade the mainland United States. There is a rifle behind every blade of grass."
Oh, sorry, I didn't look at every posted link, as I thought they were all further references to the same thing. Yes, this is a good one.
Yamamoto was AT SEA precisely because he had gently resisted the warlords in both the Army and the Navy, and that was his "punishment." Whether he said what is mythically attributed to him, the second quotation is likely accurate. Not that it would have stopped the militarists from trying.
