Query: Good Beginning, Ultimately Unsatisfying

Right up until the shooting starts, it's a great book. Beyond that point, too many players are using cards they would no longer have. The authors seem to have forgotten that most US cities came to terms with imminent attack long ago, and that at the end of the threatened scenario one side would still be in a position to offer deals that the other would no longer be in a position to refuse. Militarily spot-on, financially iffy. Beyond a certain point, economics does not play a role in policy decisions at a leadership level. A President that ignored that would not remain President very long.
