Iran-Israel War: World leaders reacted to President Donald Trump’s announcement that the United States has entered Israel’s war against Iran by bombing three nuclear sites of the Islamic Republic in the second week of the conflict on Satuday night (US time).

Israeli Prime Minister Benjamin Netanyahu said Trump’s bold decision will change history. “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,” Netanyahu said.

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

‘Catastrophic consequences for civilians’

“There is a growing risk that this conflict could rapidly get out of control – with catastrophic consequences for civilians, the region, and the world,” Guterres said in a statement as reported by news agency Reuters.

“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,” he said.

Speaking from the White House on Saturday night (US time), President Trump dubbed Iran as "the bully of the Middle East" and warned that the Islamic country "must now make peace." Trump's statement came after the US attacked three Iranian nuclear sites — Natanz, Isfahan and Fordow — further escalating the ongoing conflict between Iran and Israel.

"Iran's key nuclear enrichment facilities have been completely and totally obliterated. Iran, the bully of the Middle East, must now make peace," the US President said.

Iran's Foreign Minister Seyed Abbas Araghchi said that US attacks will have 'everlasting consequences'

“The United States, a permanent member of the United Nations Security Council, has committed a grave violation of the UN Charter, international law and the NPT by attacking Iran's peaceful nuclear installations,” Araghchi said in a post on X. 

Outrageous and will have everlasting consequences: Araghchi

The events this morning are outrageous and will have everlasting consequences, he said, adding that each and every member of the UN must be alarmed over this extremely dangerous, lawless and criminal behaviour.

“In accordance with the UN Charter and its provisions allowing a legitimate response in self-defense, Iran reserves all options to defend its sovereignty, interest, and people,” the Minister said. 

The attack was, by and large, condemned, with world leaders pushing for a diplomatic dialogue for peace in the region. 

US may be repeating past strategic mistakes: China

China condemned the US airstrikes through state media, warning Washington may be repeating past strategic mistakes. A flash commentary by CGTN, the foreign-language arm of China’s state broadcaster, described the US action as “a dangerous turning point.”

“History has repeatedly shown that military interventions in the Middle East often produce unintended consequences, including prolonged conflicts and regional destabilization,” the commentary stated, referring to the 2003 Iraq war.

It said a measured, diplomatic approach that prioritises dialogue over military confrontation offers the best hope for stability in the Middle East, according to reports.

Venezuela condemned the US ‘military aggression’. The country's foreign minister, Yvan Gil, posted on Telegram demanding an immediate ‘cessation of hostilities’.

"The Bolivarian Republic of Venezuela firmly and categorically condemns the bombing carried out by the United States military, at the request of the State of Israel, against nuclear facilities in the Islamic Republic of Iran, including the Fordow, Natanz, and Isfahan complexes," Gil said in a statement as quoted by Reuters.

‘Diplomatic dialogue for peace’

Mexico's foreign ministry urgently called for diplomatic dialogue for peace between the parties involved in the Middle East conflict.

"In keeping with our constitutional principles of foreign policy and our country's pacifist conviction, we reiterate our call to de-escalate tensions in the region. The restoration of peaceful coexistence among the states of the region is the highest priority," it said in a post on X.

Cuba's president, Miguel Díaz-Canel, also condemned the attack.

There is no military solution. The only path forward is diplomacy. The only hope is peace.

"We strongly condemn the US bombing of Iran's nuclear facilities, which constitutes a dangerous escalation of the conflict in the Middle East. The aggression seriously violates the UN Charter and international law and plunges humanity into a crisis with irreversible consequences," Canel said in a post on X.

Iran should return to the negotiating table: UK PM

"Iran's nuclear programme is a grave threat to international security. "Iran can never be allowed to develop a nuclear weapon, and the US has taken action to alleviate that threat. The situation in the Middle East remains volatile and stability in the region is a priority. We call on Iran to return to the negotiating table and reach a diplomatic solution to end this crisis," Keir Starmer said in a statement.
