There he was in his sailboat in the middle of the Atlantic, all alone and loving it. Well, there was a US Navy carrier group on his southern horizon, but he was a Navy guy himself, so he didn't mind.

Their impossible aerobatics were bad enough—but then they started shooting at each other, and at the Navy, with nukes. Little ones at first, but winding up with a 500 megatonner at 90 miles that fried every piece of electronics within line-of-sight.
