UN Secretary-General, world leaders speak on US attack of Iran nuclear facilities

Antonio Guteress, United Nations Secretary-General

Following the announcement by President Donald Trump that the United States bombed three nuclear sites in Iran, the United  Nations Secretary-General, Mr António Guterres has urged cautious diplomacy with some world leaders supporting while others condemned the move.

 

The UN Secretary-General said he was gravely alarmed by the use of force by the United States against Iran today 22 June 2025.

 

“This is a dangerous escalation in a region already on the edge – and a direct threat to international peace and security. There is a growing risk that this conflict could rapidly get out of control – with catastrophic consequences for civilians, the region, and the world.

 

“I call on Member States to de-escalate and uphold their obligations under the UN Charter and other rules of international law. At this perilous hour, it is critical to avoid a spiral of chaos. There is no military solution. The only path forward is diplomacy. The only hope is peace,” Mr Guterres said.

 

On the other hand, according to Reuters, Israeli Prime Minister, Benjamin Netanyahu hailed the strikes as a “historic turning point” and thanked the US for using “righteous and awesome might.” Defence Minister Yoav Gallant echoed the same sentiments.

 

The UK Prime Minister, Keir Starmer said the action addressed the nuclear threat but urged the warring parties to return to negotiations. EU leaders generally agree diplomacy remains essential while backing preventive measures.

 

Australia, Japan, New Zealand, Qatar, and South Korea echoed concerns about destabilization and pushed for restraint and renewed dialogue.

 

Iran’s Foreign Minister labelled the strikes violations of the UN Charter and threatened retaliation. Venezuela, Cuba, and Mexico condemned the US action as illegal aggression. Czech Rebublic and Slovenia urged immediate ceasefire and stopping the military hostilies.

 

While Israel and Western governments view the strikes as a decisive move against proliferation, a large group of nations and international bodies are deeply concerned about destabilization and potential refugee, humanitarian, and regional war fallout. Iran and its allies are preparing for reciprocal actions.
