"More realistic -- and therefore more chilling -- would be the scenario where Iran declares an oil embargo a la OPEC in 1973, which Browder thinks could cause oil to double to $131 a barrel. Other outcomes include an embargo by Venezuelan strongman Hugo Chavez ($111 a barrel), civil war in Nigeria ($98 a barrel), unrest and violence in Algeria ($79 a barrel) and major attacks on infrastructure by the insurgency in Iraq ($88 a barrel)."
Doesnt seem that far-fetched to me...However i agree that a the title of the article is misleading.
