Trump Announces Economic D-Day Against Iran, Warns Global Supporters
Donald Trump says the United States will use very strong economic pressure against Iran.
He called the plan an “economic D-Day” and said it would isolate Iran.
He warned other countries not to help Iran through banks, businesses, airports, or government agencies.
The plan would target oil smuggling, money transfers, exchange houses, and companies used to avoid restrictions.
Trump said the pressure would stop Iran from supporting armed groups and obtaining nuclear weapons.
Talks between the United States and Iran about ending the war have stopped making progress.
One major disagreement is who controls shipping through the Strait of Hormuz.
Trump said the strait is open, but Iran’s parliament speaker said it will stay closed until US commitments are met.
Trump also threatened Oman if it interfered with his administration’s talks with Iran.
Donald Trump announced what he called the most crushing economic operation ever taken against a country, describing it as economic warfare and isolation against Iran.
Trump warned countries whose financial institutions, businesses, airports, or government entities support Iran that they would face tremendous economic consequences.
The measures target Iran’s alleged economic lifelines, including oil smuggling, financial transfers, exchange houses, ship registries, and front companies.
US-Iran talks to end the war have stalled, with the Strait of Hormuz and the terms of a June 17 memorandum remaining major disputes.
Iranian Parliament Speaker Mohammad Bagher Ghalibaf said the strait would remain closed until the United States meets commitments including lifting the blockade and easing sanctions.
