Nien
Was Michael Corleone quoting is Father. (written by Mario Puzo & Francis Ford Coppola)
All men dream: but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find that it was vanity: but the dreamers of the day are dangerous men, for they may act their dreams with open eyes, to make it possible. -Seven Pillars of Wisdom (1922), T.E Lawrence
No, it’s "Nein", and you’re right, it wasn’t in the “Art of War”.
Since you brought up “The God Father,” I wanted to add that I recently went wine tasting. I wasn’t too impressed with his wine, but I was impressed with the Tucker Sedan. Here’s another picture. I love old cars. Some of the Tuckers were valued at $1,200,000. I haven’t watched the movie yet, though.
