Query: weak, bordering on bad

Judging from the book's name and the cover (a G.I. with face-paint in the jungle setting), you'd think it's a book about Vietnam War. Wrong! The book is about conspiracy in the government and events that take place in Washington. Horrible character development, I'm truly puzzled why publisher decided to go for it. Shame on the author for using Vietnam as a cheap sale tactic and waste of the beautiful trees.
