With discussions scheduled to resume in December, everything is on hold for the moment, which works to the advantage of the U.S. and its partners. Western economic sanctions are still in place, Iran's uranium enrichment program remains suspended, and international inspectors are still on the ground monitoring the country's nuclear sites. In short, the pressure is still on Iran to reach a deal. Among the sticking points still on the table is how many centrifuges Iran can have to continue enriching uranium that could be used to build a bomb. Iran, which insists its nuclear program is purely peaceful, wants to keep as many as 20,000 of the machines to supply its electric power reactors and produce medical isotopes for hospitals. The U.S. and its allies say that's far more than the country needs for those purposes and wants a limit of 4,000 or less.
