Query: Time to Re Write the History Books

With a paltry budget of $3bil a year, the CIA's counter intelligence operation had to fight a KGB/GRU monstrosity 20 times its size, one wonders how the West won the Cold war. For far to long, any time the KGB was implicated in a situation it was dismissed by the press as some kind of "right wing hyperventilation". Many of the cold war martyrs canonized by the left, i.e. Allende, turned out to be on the KGB's payroll. Simply put, this book has the potential to change the history of the Cold War as we know it.
