This was, I must say, my first Tom Clancy read. The plot was quite good involving a missing nuclear device from Israel; Terrorists of Arab and German extraction as well as a Native American accomplice. Many side plots including a duel between a U.S. and Soviet submarines. The book definitely shows how a real War could escalate out of control due to much confusion. Alot of good spy activity between the major players. The characters were well developed.The hero was CIA Deputy Director Jack Ryan. For my taste, though others may disagree, I found him to be a bit too much of a good guy and superhuman to be believable. I liked the book and found it to be a good -but even with the fine plot, at 914 pages- it was a ponderous read.
