Smart Take | Five US Citizens are Free After Prisoner Swap with Iran

Four men and one woman who have been imprisoned in Iran for years are on their way home as part of a prisoner exchange agreement that gives Tehran access to $6 billion in oil revenues previously frozen under US sanctions. USIP-Wilson Center Distinguished Fellow Robin Wright provides insights into how the negotiations happened, what pushed Iran to make this deal, and how the $6 billion will be administered. The deal comes after months of indirect talks mediated by Qatar, which began in February of last year.
