Query: Not even up to Op-Center standards

Sorry, but Tom has been mailing these in for awhile now, and this one is just beyond belief. At least 300 pages too long, packed with errors and inconsistencies, and worst of all, the Jack Ryan that I used to enjoy has been transformed into a foul-mouthed shrew, obsessed with sex.Please, can /anyone/ imagine an American president saying to the British prime minister 'Thanks pal!'.And the 75 references to 'Japanese sausage'? Ending the book with that???Not to mention the endless and shrill political diatribes in which we get to learn yet again that Clancy despises tree huggers, abortion, liberals and queers.This was a sad, sad effort. Or rather, lack of effort.
