Query: A poor effort by Clancy-- recommend others.

With this overly long book, Tom Clancy is opening the door for other thriller writers to gain the prominence they deserve. I personally prefer to read writers who have some background in what they write about, not those who invent everything. Stephen Coonts is a former combat pilot who knows whereof he writes. Bob Mayer, whether writing under his own name or the pen names Joe Dalton and Bob McGuire, is a former Green Beret who has a bunch of very good books out there begging to be read. Check them out.
