Though oWAR and dWAR do isolate the two halves of bWAR, they cannot be summed to reach the overall figure. There are a lot of minor intangibles that are too particular to dive into here, but the basic roadblock is the positional adjustment. bWAR, oWAR, and dWAR all incorporate some sort of adjustment for position, making it possible to compare shortstops to first baseman. But because oWAR and dWAR both include an adjustment, summing them would double the magnitude of this factor as compared to bWAR."

Good summation. It's also the reason Mike Trout can catch 3 routine fly balls in Centerfield and his dWAR score goes up, and why Don Mattingly can scoop 3 badly thrown balls out of the dirt at 1st Base, and his dWAR score goes down.
dWAR is vicious with 1st Basemen and Right Fielders.
I think Defensive WAR is much harder to quantify then offensive WAR.
