US to Soften Demands on Iran Nuke Programs?

The United States is considering softening its demands that Iran end its uranium enrichment program.

Months of negotiations between Iran and six world powers have failed to shrink the future capacity of Iran's enriched uranium.

The U.S. believes the regime will use it to make nuclear warheads. Now it's considering a proposal that allows Tehran to keep nearly half of the program, but puts constraints on possible paths to developing nuclear weapons.
    
Iran says it wants to use the technology for peaceful purposes.
