I disagree with Khalezov's opinion at 14:42 that OKC is "in the middle of nowhere" and had "no particular significance" as a target other than to demolish records linking Harari and Clinton and the Mena investigation. Why he makes that inference but dismisses any possible governmental motive as ridiculous, I don't know, but OKC's location has some occult significance:
Greater Oklahoma City Economic Development - Incentives Greater Oklahoma City is in the geographic center of North America equidistant from the east and west coasts and major trade partners of Canada and Mexico. www.okcchamber.com/page.asp?atomid=816
Harari/Hariri -- there's a name that has quite a lot of tension in the ME associated with it.
