Iran, the United States and five other countries appear to be on the brink of an agreement to curb Iran’s nuclear efforts — in return for easing crippling Western sanctions. Secretary of State John Kerry is arriving in Geneva today in a bid to finalize the agreement. On Thursday, White House spokesperson Jay Carney signaled the easing of sanctions would be limited.

Jay Carney: “In exchange for concrete, verifiable measures to address the P5+1’s concerns during the first step, the P5+1 would consider limited, targeted and reversible relief that does not affect our core sanctions architecture. That core sanctions architecture would be maintained until there is a final comprehensive, verifiable agreement that resolves the international community’s concerns.”
