The Corps did all they could given the information they had at the time.  If I recall, the rain event was record-breaking by a long shot, but the actual flood which ensued was not.  The much-derided photos and videos of the flood gates at Old Hickory Dam wide open actually saved the city.  The dam itself was within mere feet of overtopping, and washing out the earthen portion of the dam.  Had this happened, the entirety of Old Hickory Lake would've dumped onto the already swollen river.

What are we talking downtown, East Nashville, and the rest of the city if the Old Hickory Dam burst/collapsed, would there be anything left of the city?

Without actually doing some 3D surface-hydro modeling, it's hard to say exactly.  But suffice to say, the water would've been significantly higher and moving faster.  Anything close to the river would've sustained more damage than it did.

Wasn't there some decision based on a dam in Kentucky too... Wolf Creek, which at the time was deemed decrepit and in need of a rebuild? I understand that very little has been done to address that need.

If I recall, the work had been completed on Wolf Creek by that time.  I was at the Wolf Creek Dam in 2006 or 2007, while studying Geology at TTU and the work was mostly completed then.
