The latest report of the U.S. intelligence said that Iran stopped its nuclear arms drive in 2003, thus confirming what the International Atomic Energy Agency's (IAEA) has been saying over the last few years.

According to diplomats close to the IAEA, the Middle Eastern country has stopped its atomic weapons program in late 2003 and now doesn’t seem determined to develop nuclear arms at all.

However, the Islamic country has continued the process of uranium enrichment and could have enough material to build a bomb between 2010 and 2015 the National Intelligence Estimate (NIE) report released on Monday said.

The IAEA hasn’t found any evidence of undeclared material had been found during the inspections. IAEA Director General Mohamed ElBaradei has constantly repeated that the U.N. agency hasn’t concluded that Tehran was pursuing a nuclear weapons program.

Although the inspectors validated the efforts made by Iran, more verification work is required and Tehran must improve transparency and cooperation, the Vienna-based diplomats said.

The U.N. backed agency was "not in a position to provide credible assurances about the absence of undeclared nuclear material and activities," ElBaradei's said in his November report regarding the situation. The IAEA Director General has been under constant pressure for allegedly being to soft on Iran and overstepping his mandate by negotiating a separate cooperation work plan with Tehran.

The report of the National Intelligence Estimate came just as the United States and it partners are working on another round of harsher UN Security Council sanctions against Tehran because it’s refusal to halt the uranium enrichment program.

However, this report changed nothing on the new sanctions drive according to the European diplomats. With the United States reconsidering its position, Russia would agree on the sanctions.

The conclusions of the NIE report should be seen as an "opening through which to pursue negotiations," one diplomat in Vienna said.
