Washington: President Donald Trump pulled the United States out of an international nuclear deal with Iran, raising the risk of conflict in the Middle East, upsetting European allies and casting uncertainty over global oil supplies.

Trump said in a televised address from the White House that he would reimpose U.S. economic sanctions on Iran to undermine “a horrible one-sided deal that should have never, ever been made.” The 2015 agreement, worked out by the United States, five other world powers and Iran, lifted sanctions on Iran in exchange for Tehran limiting its nuclear program. The pact was designed to prevent Iran from obtaining a nuclear bomb.

But Trump complained that the accord, the signature foreign policy achievement of his Democratic predecessor, Barack Obama, did not address Iran’s ballistic missile program, its nuclear activities beyond 2025 or its role in conflicts in Yemen and Syria.

Abandoning the Iran pact was one of the most consequential decisions of Trump’s high-stakes “America First” policy, which has led him to withdraw the United States from the Paris climate accord, come close to a trade war with China and pull out of an Asian-Pacific trade deal.
