Absent appropriate public pressure, my guess is that there will be no House or Senate hearings on the OKC bombing.
Sources close to the Pentagon study say Timothy McVeigh did play a role in the bombing but peripherally, as a "useful idiot." The multiple bombings have a Middle Eastern "signature," pointing to either Iraqi or Syrian involvement."

At the time, William Colby, former CIA Director, was an editor for the publication. I believe his status as editor contributes to the credibility of the article.
It looks like the evidence supports the Pentagon report conclusion.
