Tensions between Donald Trump and Italian Prime Minister Giorgia Meloni escalated Tuesday after the U.S. president publicly rebuked one of his closest European allies, accusing her of lacking “courage” and failing to support Washington’s efforts against Iran.

In a phone interview with Italian daily newspaper Corriere della Sera, Trump called Meloni “unacceptable” and said he was “shocked” by her stance, according to the outlet’s English-language version.

The dispute with Trump was further fueled by Meloni’s criticism of his recent remarks targeting Pope Leo XIV, which she called “unacceptable,” prompting Trump to respond that “she is the one who is unacceptable.”

In a scathing rebuke of the Vatican’s call for Middle Eastern de-escalation, President Trump took to Truth Social to blast Pope Leo XIV. Labeling the pontiff “WEAK on Crime” and “terrible for Foreign Policy,” Trump warned him to “focus on being a Great Pope, not a Politician.” The post, which quickly went viral, accused the first American pope of “catering to the Radical Left” at the expense of global security.

In the interview to Corriere della Sera Trump also reiterated criticism of Pope Leo, saying the pontiff “has no idea what’s going on in Iran” and “doesn’t understand” what is at stake.

She “isn’t giving us any help, I’m shocked by her,” Trump said about Meloni in the six-minute conversation.

He went further, accusing Meloni of relying on Washington while refusing to act.

“They depend on Donald Trump to keep it open,” he said, referring to global energy routes through the Strait of Hormuz.

The comments mark a sharp shift in tone toward Meloni, who attended Trump’s 2025 inauguration and was praised by him as “a great leader” just weeks ago.

The White House and Meloni’s office did not immediately respond.

The public rift comes as Meloni has begun distancing herself from both Washington and Jerusalem amid mounting domestic and political pressure over the widening Middle East conflict.

On Tuesday, Meloni confirmed in a statement that Italy had suspended the automatic renewal of a long-standing defense cooperation agreement with Israel, signaling a significant recalibration in ties.

“In light of the current situation, the government has decided to suspend the automatic renewal of the defence agreement with Israel,” she said, according to Reuters.

The move follows recent tensions between Rome and Jerusalem, including Israeli warning shots fired near Italian troops serving in southern Lebanon under a U.N. mandate, as well as growing Italian criticism of Israeli military operations in the region.

Israel downplayed the impact of the decision, saying the agreement was largely symbolic and “has never contained any substantive content,” Reuters reported.

In Israel, opposition leader Yair Lapid sharply criticized the government following Italy’s move.

“Italy’s decision to suspend the defense cooperation agreement with Israel is another embarrassing failure of the prime minister and the non-existent foreign minister,” Lapid wrote on X.

“Meloni is not a left-wing progressive European leader,” she added. “She belongs to the conservative right and understands the need to fight terrorism.” 

Meloni’s shift reflects what analysts describe as a broader political repositioning, as the war’s economic fallout, particularly rising energy costs, weighs heavily on Italy’s import-dependent economy and public opinion.

Italy’s Foreign Minister Antonio Tajani defended Meloni, reaffirming Italy’s alliance with the United States while emphasizing that cooperation must be grounded in “loyalty, respect and mutual frankness.”

The escalating tensions highlight growing fractures within Western alliances as the U.S.-led confrontation with Iran reverberates across Europe, forcing leaders like Meloni to balance strategic partnerships with domestic political realities.
