I'd wager:
500:1 the U.S. is responsible (and it's intentional)
200:1 the true reason we went to war with Iraq was also to keep them from trading oil in non-$$ currencies.
20:1 Interfering with India's internet connection will ultimately cost American jobs when they start outsourcing to the U.S, since the dollar isn't going to stay above the Rupee much longer.
15:1 the catalyst for this action is the oil bourse
5:1 not long from now, when Iran gets its internet back, massive funding will be use researching the question "Is it more economical to drill for oil through sand or through glass?"
