World leaders reacted to President Donald Trump’s announcement Saturday that the U.S. had carried out a “very successful attack” on three nuclear sites in Iran, including Fordo.

“This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISRAEL, AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR,” Trump posted on Truth Social.

Here’s how world leaders reacted after the attack.

Israeli prime minister Benjamin Netanyahu said “Trump’s bold decision will change history. Speaking minutes after the attack, Netanyahu said, “President Trump and I often say: ‘Peace through strength.’ First comes strength, then comes peace. And tonight, Donald Trump and the United States acted with a lot of strength,”

Meanwhile, United Nations Secretary-General Antonio Guterres on Saturday warned that the U.S. strikes on Iran represent a dangerous escalation in an already volatile region, posing a serious threat to global peace and security.
