“All sides must return to negotiating table”: World leaders react to escalation between Iran, Israel, and U.S.

EU High Representative for Foreign Affairs and Security Policy Kaja Kallas called on all parties involved in the military standoff around Iran to return to talks. At the same time, she reaffirmed the EU’s stance that Iran must not obtain nuclear weapons.

“Iran must not be allowed to develop a nuclear weapon, as it would be a threat to international security. I urge all sides to step back, return to the negotiating table and prevent further escalation. EU Foreign Ministers will discuss the situation tomorrow,” Kallas said.

UK Prime Minister Keir Starmer also called Iran’s nuclear program a major threat, while noting that the U.S. has taken action to curb it.

“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,” Starmer wrote.

Senate Democratic Leader Chuck Schumer demanded answers from President Donald Trump following the strikes, according to CNN.

In a statement, Schumer said Trump must give the American public and Congress clear answers about the strikes and what they mean for U.S. national security.

“No president should be allowed to unilaterally march this nation into something as consequential as war with erratic threats and no strategy,” Schumer said.

He called for immediate action on the War Powers Act, urging Senate Majority Leader John Thune to bring it to the floor. Schumer also asked senators from both parties to support it, saying he would vote in favor.

“Confronting Iran’s ruthless campaign of terror, nuclear ambitions, and regional aggression demands strength, resolve, and strategic clarity. The danger of wider, longer, and more devastating war has now dramatically increased,” Schumer added.

European Council President Antonio Costa posted on X: “Deeply alarmed by the news arriving from the Middle East. I call on all parties to show restraint and respect for international law and nuclear safety.  Diplomacy remains the only way to bring peace and security to the Middle East region. Too many civilians will once again be the victims of a further escalation. The EU will continue engaging with the parties and our partners to find a peaceful solution at the negotiating table.”

• In the early hours of June 22, U.S. President Donald Trump announced airstrikes on three Iranian nuclear facilities. According to him, the U.S. military targeted sites in Fordow, Natanz, and Isfahan.
• Meanwhile, Iran’s Atomic Energy Organization said it would continue its operations despite the attacks by the U.S. and Israel.
