Iran's Pezeshkian tells Pope Leo: Tehran stands firm on diplomacy
Synopsis
Iran's President Pezeshkian has written directly to Pope Leo to praise his 'moral stance' against US-Israeli military action — a soft-power move that puts the Vatican at the centre of the Iran nuclear standoff. With Trump publicly rebuking the Pope and declaring Iran will never have a nuclear weapon, the diplomatic battle for international opinion is intensifying on multiple fronts simultaneously.

Iranian President Masoud Pezeshkian on Saturday, 16 May wrote to Pope Leo to commend the pontiff's 'moral stance' against US-Israeli military action, while reiterating that Tehran remains steadfastly committed to diplomacy and peaceful resolution of regional tensions. The message, reported by Iran's official news agency IRNA, comes amid an escalating war of words between Washington and Vatican City over Iran's nuclear status.
What Pezeshkian Said
In his message to the Pope, Pezeshkian expressed appreciation for the Catholic leader's position on what he described as strikes carried out by the United States in coordination with Israel. The Iranian President argued that the strikes violated international law and undermined ongoing diplomatic efforts.
Pezeshkian reiterated that Iran remains 'sincerely committed to dialogue and lawful peaceful solutions,' while preserving its right to self-defence. He also appreciated the Pope's stated commitment to 'just peace.'
Iran's Call to the International Community
Beyond his message to the Pope, Pezeshkian called on the broader international community to oppose what he characterised as 'illegal demands and dangerous policies by the United States,' urging nations to adopt a 'realistic and fair approach,' according to IRNA.
He argued that the conduct of both the US and Israel posed a challenge to the rule of law within the international system, as well as to humanitarian values and the teachings of major religions. This is not the first time Tehran has sought to frame its position in terms of multilateral legal norms — a recurring diplomatic strategy amid international pressure over its nuclear programme.
Trump Pushes Back on Pope Leo
The backdrop to Pezeshkian's outreach is a sharp public disagreement between US President Donald Trump and Pope Leo. Trump last week publicly criticised the pontiff, suggesting he appeared to support Tehran's ability to possess nuclear weapons — a position Trump said Washington would never accept.
When asked what message he hoped Secretary of State Marco Rubio delivered to Pope Leo XIV during a visit to the Vatican, Trump was unequivocal: 'Well, I can tell you this, that as far as the Pope is concerned, it's very simple — whether I make him happy or I don't make him happy, Iran cannot have a nuclear weapon.'
Trump then suggested the Pope had taken a position at odds with Washington's on Tehran — a rare and pointed public rebuke of a sitting pontiff by a US president.
Diplomatic Context
The exchange highlights the increasingly complex diplomatic geometry around Iran. Tehran is simultaneously engaged in nuclear talks, facing military pressure from US-Israeli operations, and now cultivating moral support from the Vatican — a soft-power play aimed at shaping international opinion. Notably, Pope Leo's papacy has already drawn significant geopolitical attention in its early weeks, with multiple world leaders seeking audiences or sending direct communications.
With US-Iran nuclear negotiations still in a fragile state, the coming weeks will test whether diplomatic channels can hold against the pressure of military escalation and competing international narratives.
Point of View
Not just negotiating tables, can shift the calculus. Trump's rare public rebuke of a sitting Pope, meanwhile, reflects how deeply the Iran file has become entangled with domestic US political messaging. The harder question mainstream coverage is underplaying is whether any of this diplomatic theatre is moving the actual nuclear talks — or simply providing cover for continued escalation on all sides.
