Donald Trump reinstated his “maximum pressure” campaign on Iran, signing a memorandum that reimposes economic sanctions aimed at reducing Tehran’s oil exports to zero. The policy mirrors measures taken during Trump’s first term, to prevent Iran from obtaining a nuclear weapon. Trump accused President Joe Biden of weak enforcement, allowing Iran to fund its nuclear program and Middle Eastern militias through oil sales. Iran’s uranium enrichment has reached 60, near weapons-grade levels, according to the U.N. nuclear watchdog. The policy directs the U.S. Treasury and State Department to enforce strict sanctions.
