Richard Clarke also wrote a fictional account of a near-world-war-three in the near future in Breakpoint. The global politics and technological advancements closely follow the trends discussed in Al Gore's and Thomas Friedman's books. Richard Clarke was the counter-terrorism czar whose warnings were ignored prior to 9/11. He has thought about how terrorism may occur in the digital age possibly more deeply and realistically than anyone else.
These four books all went really well together. It was a complete coincidence that I happened on them at the same time. And I recommend them all.
