World Leaders React to U.S. Strikes on Iranian Nuclear Sites

President Donald Trump announced on Saturday, June 21, 2025, that the United States had carried out a “very successful attack” on three key Iranian nuclear facilities: Fordow (Fordo), Natanz, and Esfahan. In a Truth Social post, Trump declared that all U.S. aircraft had safely exited Iranian airspace and emphasized, “IRAN MUST NOW AGREE TO END THIS WAR.” He later described the operation — involving B-2 bombers dropping Massive Ordnance Penetrators on the heavily fortified Fordow site — as a “spectacular military success” that “completely and totally obliterated” Iran’s nuclear enrichment capabilities.

The strikes marked a significant escalation, bringing the U.S. directly into the ongoing Israel-Iran conflict. Trump framed the action as necessary to prevent Iran from developing nuclear weapons and to pave the way for peace.

Iran responded with strong condemnation. Foreign Minister Abbas Araghchi called the attacks “outrageous” and a “grave and unprecedented violation” of the UN Charter, international law, and the Nuclear Non-Proliferation Treaty. “The events this morning are outrageous and will have everlasting consequences,” he stated on X. Araghchi stressed that Iran “reserves all options” for self-defense to protect its sovereignty, interests, and people, holding the U.S. fully responsible for any further escalation.

International reactions were sharply divided. Israeli Prime Minister Benjamin Netanyahu praised Trump, stating the strikes would “change history” and thanking the U.S. for coordinated action against a shared threat.

UN Secretary-General António Guterres expressed being “gravely alarmed,” describing the strikes as a “dangerous escalation in a region already on the edge” and urging immediate de-escalation and a return to diplomacy.

European leaders, including UK Prime Minister Keir Starmer, acknowledged the threat posed by Iran’s nuclear program but called for restraint and renewed negotiations. Russia and China strongly condemned the action as aggression and a violation of sovereignty. Saudi Arabia expressed “great concern,” while countries like Cuba and Venezuela issued harsh rebukes.

The strikes have heightened fears of wider regional instability, oil price volatility, and retaliatory actions. As of now, both sides appear to be weighing further moves amid urgent diplomatic efforts to prevent a broader conflict. Analysts suggest the operation set back Iran’s nuclear program significantly, though Tehran has vowed to rebuild and defend itself.
