MOSCOW — President Vladimir Putin on Monday sanctioned the delivery of a highly capable Russian air defense missile system to Iran, a game changer move that would significantly bolster the Islamic republic’s military capability and fuel Israel’s concerns. U.S. Secretary of State John Kerry objected to Moscow’s decision in a phone call to Russian Foreign Minister Sergey Lavrov, and the White House indicated the move could endanger plans to ultimately lift sanctions on Iran as part of a proposed nuclear deal. White House press secretary Josh Earnest said unity and coordination with nations like Russia is critical to the success of the negotiations.
