Query: Bobby Kennedy nearly caused Armageddon!!

This book is a remarkable piece of scholarship that provides the most thorough backdrop yet to the JFK assassination. I found the most significant part of the book to be the deep politics going on in the JFK administration. My worldview has been forever changed in learning that the character deficits of Bobby Kennedy and his obsession with getting Castro ultimately forced the Cubans to accept Soviet missiles for their own protection. Although I was taught that the Kennedy brothers heroically averted Armageddon in November 1962, it was their arrogance and inexperience that had actually pushed us to the brink in the first place! Thank you, Mr. Russo!!
