Just when you thought the Iran problem couldn’t get worse, it’s worse.

Earlier this week Tehran agreed to a deal, brokered by Brazil and Turkey, to ship out more than 2,500 pounds of its enriched uranium across the border to Turkey. In exchange the Iranians will receive fuel rods containing about 250 pounds of uranium enriched to 20 percent for use in their low-wattage Tehran Research Reactor, which the regime says will be used to generate medical isotopes (for instance, sodium iodide 131I to treat thyroid cancer).
