Warning this book is intended to make martyrs . Guerrilla Warfare: Che Guevara  by Ernesto Guevara    Warning this book seems intended to make martyrs    Over the years this book has proved far more useful to mislead potential guerrillas than to educate them.  The handmade weaponry described are ineffective and or failed tools of war. The tactics suggested have led to defeat in the Americas and in Africa. The cause described has never helped the poor and down trodden.  One could readily ponder if the real intent was to make martyrs for the cause of mythical communist paradise. One wonders  how many, aside from the author, died violently because of all the above.

Ex Output:
NEG


Ex Input:
Save your money...... . Bad, bad and bad. This book could have been condensed down to 5 chapters to tell the story.  It was dragged out for no other reason then to make it a full book.  I have enjoyed this authors other books, but this was was very disappointing.  Save your money on this one ladies

Ex Output:

NEG
