Red Storm Rising is still one of my favorite books, I remember reading it the year it came out in 1986, and I still have that original Hardcover. I reread it at least once a year still to this day. The early "Jack Ryan" books were alright as well, right up until The Bear and the Dragon, the last book you can tell was written solely by Clancy.
He loved his country, you can discern that much from his books, and his non fictional series on different branches of the military were excellent as well, I bought the first one Fighter Wing while on a trip to the USA, and read it the entire flight home.
