PITTSBURGH, Pennsylvania (CNN) -- The United States, France and Britain have presented "detailed evidence" to the U.N.'s nuclear watchdog that "Iran has been building a covert uranium enrichment facility," President Obama said Friday before the start of the G-20 economic summit.

President Obama told Iran to "take concrete steps" to show it will comply with nuclear regulations.

Iran's newly unveiled uranium enrichment facility "is inconsistent with a peaceful (nuclear) program," Obama said.

"Iran is breaking rules that all nations must follow," he said....

Iran's admission comes ahead of next week's rare meeting in Geneva, Switzerland, between Iran and the five permanent United Nations Security Council members, plus Germany.

Iran's revelation of a new nuclear site could actually "strengthen their hand" as it heads into next week's talks, according to Paul Ingram, an analyst who studies Iran and nuclear non-proliferation.

"It will be seen as an indication that they are willing to play by the rules," said Ingram, the executive director of the British American Security Information Council in London, England.

He said the timing of Iran's revelation -- in between the U.N. General Assembly sessions and the October 1 meeting -- is deliberate on Iran's part.

"This will make it more difficult to persuade them to abandon enrichment," Ingram said.

In my humble opinion Iran just admitted they fear or at the very least care about what the U.N. can do to them.  Why else would Iran bother to "strengthen their hand" by sending a letter of admission about their second uranium enrichment facility?

A man or nation that fears nothing is more dangerous than one that fears something.  Iranian President Mahmoud Ahmadinejad and his administration fear the United Nations.  This backhanded way of admitting to another facility, in my view, proof of this fear.

Instead of saying this "strengthens their hand" I would offer instead the idea that they've now "shown their hand".

The United States and any other nation that are pushing for,

 Iran to "take concrete steps" to demonstrate it will comply with its international obligations to ensure its nuclear program is for civilian use and not a covert weapons program.

Should take the upper hand and give Ahmadinejad something to return home with. 

He should be given a word of warning from the U.N.'s that unless Iran complies with the U.N. demands within so many days -- they will lose whatever prestige they have gained over recent times with the U.N. and be given sanctions beyond any other.  I would also add that if after those sanctions take hold and Iran still does not comply with the U.N. demands, their so-called peaceful facilities  will suffer costly damage by members of the U.N. counsel.
