Did Nichols & McVey Work Alone?

Here is a good conversation starter:

What do you think of the oft-referred to premise that McVey & Co. were aided by a middle eastern terrorist type? There are reports of John Doe #3 and how he was supposedly of Arab descent. There is a reporter in OKC (don't remember her name) who has written a book about this. I suppose that there is some degree of credibility in this, I have often wondered about how Nichols & McVey were able to put together such a device. Nichols is a nutcake and McVey seemd to be a dumbass. McVey did not seem to receive any sort of training in the Army that included improvised explosives. I know stuff like that is on the internet, but it seems like those two would have needed some help.
