You're missing the point. Clancey's novels have a sense of realism which this takes away. Secondly, it's a PC argument. The radical leftists in Hollywood will not let the Arabs be portrayed as, in fact, they are...and was written in the book.
That's not the issue.
The issue is political correctness. The novel of TSoaF was a perfectly good thriller with villains whose motivation makes sense. The film version isn't.
I read the book too. Good one. They did have to change it a little if they were going to set the film in the present day. The Jihadists were the chief villains, but a supporting character was a post-fall-of-the-Berlin Wall East German terrorist. The Soviet Union was still around when Clancy wrote this book. (Must've been 1990).
One of the more intriguing characters was a Russell Peletier-esque American Indian Movement thug.
But there were Religion of Peace Jihadists in 1990, and there are in 2002. The screenwriters didn't have to change too many things.
The point is not any sympathy for Neo-Nazis, but the political correctness involved in "not offending the Muslims". I would not have thought you would object to Arab fanatics as bad guys.
Other points from the book that I expect to see messed with: the president's political advisor (who's also his mistress) going hysterical over the nuking of the Super bowl and urging WW III; the (Democrat) prez freaking out and attempting to nuke an arab city to demonstrate he has balls, with WW III having to be avoided by the intervention of ex-Marine CIA deputy Jack Ryan; and Israel getting yelled at for "misplacing" the nuke that the terrorists use and not telling us about it.
The point is, why change the villains from what the author intended?
It's actually an old Hollywood device to substitute far-right villains for the left-wing villains in the original book. EG, Ian Fleming's novels had SMERSCH - a Russian communist organization - as a villain. Hollywood, in From Russia with Love, changed the villain to independent operators who weren't tied to either the East or the West. Hollywood resists making communists villains, andm, apparently, is also reluctant to make arab terrorists villains, even though that's how Clancy had it.
