The United States announced that it will reimpose a naval blockade on Iran on Tuesday, coinciding with the 11th anniversary of the signing of the Joint Comprehensive Plan of Action (JCPOA). The agreement, reached on July 14, 2015, in Vienna between Iran and six world powers, aimed to limit Iran’s uranium enrichment program and prevent it from developing nuclear weapons. In return, most international sanctions on Iran were lifted, allowing the country to resume oil and gas exports to global markets.

Despite the initial success of the deal, the United States maintained some secondary sanctions. In 2018, then-President Donald Trump unilaterally withdrew the U.S. from the JCPOA, calling it flawed, and reinstated the sanctions that had been lifted under the agreement.

The renewed naval blockade marks a significant escalation in U.S. pressure on Iran, though the source does not specify the operational details or international response to the move.
