Review:
Cliche or not, this is a "Must Read" book, August 15, 2008
By David R. Cook "Dave Cook"

This is the bluntest, toughest, most scathing critique of American
imperialism as it has become totally unmoored after the demise of the
Soviet Communist empire and taken to a new level by the Bush
administration. Even the brevity of this book - 182 pages - gives it a
particular wallop since every page "concentrates the mind".
