Trump threatens economic sanctions on countries aiding Iran

U.S. President Donald Trump warned on Tuesday that any nation that assists or conducts business with Iran will face what he called an “economic D‑Day,” signaling a potential escalation of American sanctions against Tehran’s allies. The remark was made during a press briefing at the White House, where the president reiterated his administration’s stance that Iran’s nuclear program and regional activities pose a direct threat to U.S. interests and that the United States will not tolerate external support that could bolster the Iranian economy.

The statement follows a series of executive orders and legislative measures aimed at tightening financial restrictions on Iran, including secondary sanctions that target non‑U.S. entities engaging in prohibited transactions. Treasury officials have indicated that the “economic D‑Day” threat could translate into expanded asset freezes, prohibitions on access to the U.S. financial system, and heightened enforcement actions against foreign firms. International partners have expressed concern over the possible impact on global trade and diplomatic relations, while the administration maintains that the policy is intended to pressure Iran into compliance with nuclear agreements and curb its regional influence.
