Your theories are well thought out and have some logical support. There is however one problem I see. Why not blame the OKC bombing on the foreign terrorist back then ? Why shift the blame to 'domestic terrorism' ? Think of how the country would have rallied behind Clintoon because of the terrible act of middle eastern terrorism committed in the 'heartland' of America. The only possible explanation I can see is that Clintoon hijacked their plans and used them to go after those 'right wingers' who were causing him political problems.
Here are some other interesting things I remember from those of us who were frequently posting on the newsgroups back then. Right after that bombing a couple of new posters appeared who were obviously trying to persuade right wingers to support McViegh. They were unsuccessful. I also remember getting a private email from Rivero back then. After I called McViegh a mass murderer who was obviously timing the actual bombing to kill as many of the workers within the building as possible, Rivero told me in private email that McViegh got hung up in traffic and may have been trying to get the truck to explode earlier.
Just some more tidbits for you to ponder.
Possibility. Maybe they figured if they blamed the ME, then later when the book was published, they thought the ME was claim they were set up?
I have no idea, but I wonder why wasn't book published ealier if it was finished in 1991? Why the long delay?
1) The radical rightwing ideology of McVeigh played into the hands of the blame-oriented partisan politics of the Clinton thugs.
2) It is a simpler explanation than an international terrorist thread, which, when pulled, unravels a story that may not end cleanly for the admin or the intelligence community or the big military dealers who lobby Congress.
3) It's possible that some of the unnamed terrorists may have been Saudi and that some big military sales could have been jeapordized.
4) PLUS: there has been more than speculation that Terry Nichols had a tie to the Phillipines terrorist organization that has ties to Al Queda.
