World leaders express concern over recent U.S. strikes on Iran's nuclear sites, urging dialogue and caution to prevent further conflict in the Middle East.
In the early hours of June 22, 2025, tensions rose significantly as the U.S. launched military strikes on three nuclear facilities in Iran, directly engaging in a conflict extending from Israel's ongoing war. The nature of this military intervention spurred immediate reactions from world leaders, many of whom voiced concerns about potential consequences across the Middle East.

In the United Kingdom, Prime Minister Keir Starmer stated that the U.S. action was necessary to address the nuclear threat posed by Iran but urged the nation to return to diplomatic discussions. Meanwhile, Australia echoed sentiments of caution, emphasizing the necessity of continued diplomatic engagement and warning against the destabilizing effects of Iran's nuclear pursuits.
From New Zealand, Foreign Minister Winston Peters voiced the importance of diplomacy, insisting on the urgency to prevent further military actions in the region. Meanwhile, South Korea convened to evaluate the repercussions of the strikes on its own security and economic stability.
Countries like Mexico and Cuba also joined in the call for peace, with Mexico advocating for diplomatic dialogue while Cuba condemned the military action as a dangerous escalation. Chile's President Gabriel Boric questioned the legality of the strikes under international law, urging for an immediate end to hostilities. Similarly, Venezuelan officials denounced the attack as an aggressive and unjustifiable act.
With varied perspectives emphasizing the need for negotiation and a resolution to rising tensions, the world watches closely for potential shifts in the geopolitical landscape and the implications for global security.
