US reviews 'failed' Iran nuclear deal

US Secretary of State Rex Tillerson branded the Iran nuclear deal a failure Wednesday as President Donald Trump ordered a review of how Washington is countering the threat from Tehran.The State Department admits that Iran has so far maintained its side of the bargain it struck with world powers in 2015 to curtail its nuclear program in exchange for sanctions relief."The Trump administration has no intention of passing the buck to a future administration on Iran," Tillerson told reporters.
