The United States and the rest of the world face the most sophisticated underwater threat by drug smugglers and terrorists by covert NARCO submarines and semi-submersibles. What was only the technological domain of the two major superpowers is now available to anyone with money and a desire to operate an export business of drugs or nuclear terror. Signal Mountain, TN (PRWEB) April 21, 2010 -- The newest privately released book on the US market called, Drug Subs (www.drugsubs.com) will forever change readers' ideas about the safety net of the United States security. www.drugsubs.com According to DrugSubs.com, 30% of all the cocaine in the US worth $21 billion dollars is smuggled in by fiberglass semi submersible fiberglass submarines manufactured deep in the jungles of Columbia. DrugSubs.com reports, North Korea is also supplying drug cartels in Columbia and rouge nations like Iran with deeper operating submarines for drug smuggling and terrorist's missions. "The first terrorist nuclear weapon detonation on United States soil may actually be delivered by a North Korean built submarine or a Columbian built semi-submersible launched by an offshore commercial ship" Dr. Robert Spalding, author of Drug Subs. DrugSubs.com informs the reader that the newly discovered secret fleet of narco submarines were for years nicknamed "Big Foot" by the US NAVY because no one in the military had ever seen one until1997 when one was captured. The book, Drug Subs, written by Dr Robert Spalding is the first factual book in print that describes the history, the current manufacturing process and the future of the clandestine Narco Fleet that now sails world wide with near impunity. This 37,000 word book is pictorially documented with unique photos of this new underwater threat plaguing not only the United States but Europe, Africa and other countries as well. Drug Subs outlines how the next major terrorist attack may very well be by our less protected coastlines of the United States rather than by air attack.
