Surprising only those who haven’t paid attention to Iran’s history for the last 30 years, Iranian authorities waited until the last day to formally request “changes” to the latest IAEA proposal.

Iran has formally asked for changes to an International Atomic Energy Agency proposal to ship nuclear fuel out of Iran for reprocessing abroad.

The response represents a setback in attempts by the international community to negotiate with Iran over its nuclear ambitions. Just last week, negotiators from the U.S., France and Russia left the table with Iranian counterparts in Vienna optimistic that they had hammered out a deal acceptable to all parties, including Iran.
