Iran and the Joint Comprehensive Plan of Action (JCPOA)

For months, the United States was humming and hawing about how and on what
terms it would return to the nuclear deal with Iran, as doubts were
percolating in world capitals about whether the administration of Joe Biden
even wanted to revive the deal. But during indirect talks between Iran and
the US over the last couple weeks in Vienna, Washington startled just about
everyone involved when it suddenly presented plans detailing how it would
remove sanctions on Iran if it were to roll back its nuclear programme for
both countries to back come into compliance with the Joint Comprehensive
Plan of Action (JCPOA).
