No one can accuse Donald Trump of lacking faith in his own abilities. Tweeting early Tuesday morning, the president said he was aiming for world peace, “nothing less,” as he praised his new sanctions against Iran. “The Iran sanctions have officially been cast,” he wrote. “These are the most biting sanctions ever imposed, and in November they ratchet up to yet another level. Anyone doing business with Iran will NOT be doing business with the United States. I am asking for WORLD PEACE, nothing less!” Iran’s President Hassan Rouhani hit out at the White House for its reinstatement of economic sanctions, describing the measures, which came into effect overnight, as “psychological warfare.” The sanctions take aim at various sectors including Iran’s automotive industries, its trade in gold and other precious metals, as well as aluminum, steel, coal, and software used in industrial processes. The sanctions come after the U.S. withdrew from the Iran nuclear deal this year.
