Iran is about the only oil supplier still willing to deal with Greece, as most oil traders and major companies are avoiding the country amidst fears that Athens will default on its debt, Reuters reports. “Our finance department just refuses to deal with them. Not that they didn’t pay. It is just a precaution,” an unidentified trader told the news agency. But Greece’s last-ditch option to ensure a steady supply of fuel is running against efforts in both Washington and Brussels to put pressure on Iran after a UN report earlier this week suggested Tehran is trying to acquire nuclear weapons capability.
