As the modern world becomes more advanced, it becomes more technologically dependent; thus more fragile.
Technology, however, is its 'Achilles heel' so to speak. As this technology becomes increasingly complex and refined, it becomes more vulnerable to an EMP attack. When an individual country relies on such frail, delicate electronic systems to run the economy, industry, and the military, it inevitably leaves itself open to its enemies. For whatever political reason or religious doctrine, an EMP attack on such a country would leave the whole infrastructure and capability of that society to run itself in ruins.
This book is a scenario of what could happen in a microsecond, any time, any place, anywhere!
