After decades of electricity shortages because of war, corruption and mismanagement, oil-rich Iraq has become heavily reliant on imported Iranian gas to meet its electricity needs. The shortages in recent months are in part due to U.S. restrictions on transferring funds to Iran. Imports from Iran are especially vital during the scorching summer months when Iraqis are forced to pay for private diesel generators or suffer through temperatures that often exceed 50 degrees Celsius (122 degrees Fahrenheit). Iraqi officials have defended a deal inked this week to barter oil for gas with Iran, saying that the deal does not violate U.S. sanctions on Tehran and that it will help alleviate a worsening electricity crisis in Iraq. Should the world be allowed to trade without threats from the United States ?
