Wondering why so much cheap heroin now reaching U.S. streets? Read this book. Drugs produce money, and money ... political leverage. Only five "rightist" regimes remain in the Western Hemisphere. Peru was last to elect a leftist president, and Mexico will be next. Al-Qaeda has had nothing to do with this. Herein lies the culprit and its localized source of political advisers and campaign funding. Blocking this incursion before it too greatly affects the homeland may take augmenting a few host-country outposts in Colombia, Panama, and Mexico with lone U.S. infantry squads. Part Three has the unconventional warfare techniques those squad members will need to vie with many times their number of drug runners and revolutionaries. It also shows how to blanket an area with secretive fire team zones. As America's first narco-counterinsurgency manual, this book could also turn the tide in Afghanistan.
