As negotiations are poised to resume between Iran and the six powers seeking to rein in Iran's nuclear program, it is difficult to avoid a sense of déjà vu.
For years now, the UN Security Council has demanded Iran suspend uranium enrichment. Tehran continues to expand its nuclear program and insists it will never compromise its right to enrich, the United States continues to tighten sanctions on Iranian trade and finances, and alarms are raised about Iran being able to sprint to a nuclear bomb with little warning.
Yet, with a new Iranian president and negotiating team, there are grounds for cautious optimism that talks this time can be different. Although Iran continues to enrich uranium and add to its nuclear complex, time remains to negotiate an agreement that adequately guards against Iran building nuclear weapons.
