Kerry arrives at London's Stansted AirportThrough Caren Bohan and Will Dunham WASHINGTON (Reuters) – The Obama administration insisted on robust safeguards in a nuclear care for Iran and has no illusions in regards to the dangers that the Islamic state might now not apply thru on its tasks, Secretary of State John Kerry mentioned on Sunday. Kerry sought to reassure skeptics in the Congress who worry that the six-month settlement offers Iran an excessive amount of leeway and that it will prove the use of it as a stalling tactic. Kerry told CNN that U.S. officials entered into the deal with their eyes "absolutely broad open." "We haven’t any illusions. The deal reached by using Iran and six world powers, together with the United States, gives Iran some preliminary relief from sanctions in trade for halting its most sensitive nuclear work, the excessive-grade enrichment of uranium.
