Iran warned nearby countries they could be treated as enemies and have their interests targeted if they join the United States’ economic campaign against Tehran. Supreme National Security Council Secretary Mohsen Rezaei issued the warning in a Saturday interview with state broadcaster IRIB, saying Iran would first negotiate and seek to separate neighboring states from Washington before giving them time to reconsider and ultimately acting against those that continued to support the US. Rezaei also warned that Iran could prevent oil exports through the Persian Gulf and Strait of Hormuz and target alternative shipping routes. He said the Strait of Hormuz remains closed despite US claims to the contrary and would not reopen until Washington fulfills its commitments. The warnings followed President Donald Trump’s pledge to launch the "most crushing economic operation" yet against Iran, impose "tremendous economic consequences" on countries providing Tehran "any type of lifeline," and Treasury Secretary Scott Bessent’s statement that, "You’re either with us or against us." Iran’s Foreign Ministry condemned the planned measures as "extraterritorial sovereignty" over United Nations member states, while reports said Tehran had considered targeting US allies in Europe that support Trump’s operations.
