WASHINGTON—With the signing of a historic agreement over Iran’s nuclear program, President Barack Obama has effectively shredded the foreign-policy playbook that had guided the U.S. on the world stage for decades.
Now comes another hard part.
He must turn to selling the deal to a skeptical Congress, and to managing relationships in a volatile Middle East, where the notion of an emboldened Iran has rattled longtime U.S. allies, particularly Israel and Saudi Arabia.
Some of the core milestones for the implementation of the agreement, sealed in Vienna on Tuesday, will overlap with the 2016 U.S. presidential campaign, the one that will choose Mr. Obama’s successor, ensnaring them in an unpredictable political dynamic. And after more than three decades of hostility and mistrust between the U.S. and Iran, American officials are uncertain how compliant Tehran will be over the deal’s time frame.
