This is a very American centric book, which is fair enough, the primary author has been on various policy committees in the US administration.There is a fair amount of detail, and he spends quite a lot of time looking at the parts of American policy that have huge gaps, and the fact that successive governments have failed to address key infrastructure points and are wide open to logic bombs and attacks from hackers.It is very readable, especially as some of the networking stuff is way above my head. It does make you wonder how the UK would be affected by all of this.
