US think tank: Iran approaching nuclear threshold
A US think tank says Iran could produce enough highly enriched uranium for a nuclear device in 2 weeks if the country were to stockpile enough 20-percent enriched uranium.

The Bipartisan Policy Center says in its report for this month that if Iran is allowed to proceed with its enrichment process unchecked, the country could have 155 kilograms of the 20 percent enriched uranium by late 2012.
