In a long-ago thread, I argued that Sonny, for all his hot-headedness, made a level-headed, strategic move in sending Fredo] to Nevada to learn the casino business and (as we learned later) bankrolling Moe Green. He arranged for Fredo's safety and he planted a stake in what was to become an enormous, booming industry. That stake had an IOU attached to it
