Iran Conflict Strains Ties Between US, Europe, Vatican and Israel

International Conflict Exposes Growing Divisions Among Western Allies

The escalating situation with Iran has become more than just a military crisis—it’s now revealing deep fractures within Western partnerships that threaten long-standing diplomatic relationships. Recent developments show mounting friction between the United States and its European partners, with disagreements surfacing over military support, diplomatic strategies, and fundamental approaches to international conflict.

These tensions have manifested across multiple fronts simultaneously: Washington has publicly criticized European nations for insufficient backing, Italy has adjusted its relationship with Israel following incidents in Lebanon, and an unprecedented public dispute has emerged between the White House and Vatican leadership, involving key European political figures.

Israeli Prime Minister Benjamin Netanyahu has characterized Europe’s position as more than mere strategic disagreement, describing it during Holocaust Remembrance Day as evidence of declining moral strength and weakening commitment to defending civilization.

The current developments represent interconnected episodes where military actions, diplomatic communications, and public political statements have begun influencing and amplifying each other, creating a complex web of international tensions.

Italian-Israeli Relations Cool Following Lebanon Incidents

The breakdown in Italian-Israeli diplomatic relations developed gradually rather than through a single decisive moment. The situation began deteriorating when Italian forces serving with the United Nations Interim Force in Lebanon (UNIFIL) encountered problems in southern Lebanon, where they work to maintain border stability.

An incident involving Israeli warning shots that struck an Italian UNIFIL vehicle immediately transformed from an operational concern into a diplomatic crisis. Italy, which contributes significantly to the peacekeeping mission, could not dismiss the episode as routine. Prime Minister Giorgia Meloni’s reaction—calling the incident “completely unacceptable”—marked a clear shift from careful diplomacy to direct criticism. Her additional statement demanding that “Israel’s continued attacks in Lebanon … must cease immediately” expanded her critique beyond the specific incident to encompass Israel’s broader military operations in the region.

Foreign Minister Antonio Tajani escalated matters further by publicly condemning Israeli bombardments affecting Lebanese civilians as “unacceptable,” demonstrating that Rome’s concerns now extended beyond protecting its own forces to include broader humanitarian and legal issues. Israel responded by summoning Italy’s ambassador, mirroring Italy’s earlier decision to summon the Israeli ambassador, establishing a pattern of reciprocal diplomatic protests that signaled a transition into open disagreement.

Following this sequence of events, Italy chose not to automatically renew its bilateral defense cooperation memorandum with Israel. The agreement, originally signed in 2003 and active since 2006, primarily serves as a framework for military collaboration including equipment procurement, joint operations, and defense industry partnerships. Its renewal process is typically administrative rather than political, usually occurring automatically every five years. In practical terms, suspending the agreement immediately doesn’t substantially change existing cooperation levels. Israeli officials attempted to downplay the impact, stating it would have “no practical effect.”

However, the limited operational impact actually enhances the decision’s political significance. By halting a largely ceremonial agreement, Italy is communicating a shift in political positioning rather than dismantling concrete military structures.

Leo Goretti, who leads the Foreign Policy Program at the Istituto Affari Internazionali, explained to The Media Line that the action was primarily political. “In reality, I don’t even have direct knowledge of the merits of the agreement. My impression is similar to what you have expressed, that in this case, it is a bit like Sigonella’s speech a while ago, that is, these positions are above all positions that want to send a signal to public opinion.”

Goretti noted: “This is in line with what we said before, that is, the awareness that a change of pace is necessary on the side of the Italian position at the international level. However, it will not be easy, in the sense that we are so out of time in taking a stance, compared to other European countries.”

From an Israeli analytical viewpoint, the move reflects longer-term trends rooted in domestic political dynamics within Italy and across Europe.

Dr. Esther Lopatin, who directs the Center for European Studies at Reichman University, told The Media Line: “The decision by Giorgia Meloni, the prime minister of Italy, to suspend the defense agreement with Israel is not surprising at all. Over the last few years, Meloni has become increasingly critical of Israel. While in the past she claimed that the Likud party inspired her, in reality, criticism of Israel and of Benjamin Netanyahu has grown steadily over time, in line with the rising criticism within Italy itself.”

She referenced polling data from May 2025 indicating approximately 70% of Italians hold highly critical views of Israel, with only 18% maintaining positive opinions and just 9% supporting Israel’s Gaza policies. The widening gap between public sentiment and government policy has weakened Italian support for Israel.

Lopatin added, “Meloni wants to be liked and admired by her public, and one way to achieve this is by expressing criticism of Israel. For example, after October 7, 2023, Italy decided to impose an arms embargo on Israel due to the war in Gaza. It is politically more convenient to be critical of Israel, as this also earns her support from the left—or at least reduces criticism from the left.”

US-Europe Divide Reflects Deep Strategic Differences

The disagreement between Washington and European capitals regarding Iran stems from fundamental differences in strategic thinking, threat assessment, and political capabilities that the current conflict has highlighted rather than created.

European governments have generally maintained preferences for diplomatic engagement despite escalating Iranian tensions. This approach combines normative commitments with structural limitations rather than simply representing “soft power” preferences.

Lopatin explained that Europe’s diplomatic focus reflects both strategy and constraints. “Europe—and especially the European Union—has long believed that the best way to manage international conflicts is through diplomatic means—what is often referred to as soft power,” she said.

“In contrast to the Americans, Europeans have traditionally argued that they do not believe in relying primarily on military force, and that the best way to handle conflicts is through negotiations and diplomacy.”

This approach has historical foundations in EU engagement with Iran during the 1990s, when economic relationships were maintained alongside efforts to influence Tehran’s domestic policies.

“In the case of Iran, for many years—especially during the 1990s—they promoted what was called a ‘critical dialogue’: continuing trade with Iran while at the same time trying to encourage it to respect human rights, including the rights of women and the LGBTQ,” Lopatin said.

“In practice, this approach did not fully succeed, but many Europeans still believe we should not abandon the diplomatic track.”

Simultaneously, Europe’s position is shaped by practical limitations. “Most EU countries are relatively small, such as Belgium, the Netherlands, and Luxembourg—countries that do not have the military capacity to fight a country like Iran. Even those that do have significant military capabilities, such as Germany, France, and Italy, lack the desire to engage in a war with Iran,” she said.

“The average German or Italian is not willing to die so that Iran becomes a democracy. After all, this is not an existential war for Europe.”

Trade between the European Union and Iran remains limited compared to pre-sanctions periods but continues to exist, with European governments weighing economic consequences of escalation. Lopatin cited approximate annual EU-Iran trade at around €5 billion, with Germany and Italy among the primary European commercial participants. Germany earns approximately €1.2 billion from Iranian exports and imports roughly €200 million in Iranian goods, while Italy exports around €700 million to Iran and imports about €170 million.

“These figures show that economic considerations play a role—Europe benefits economically from its relations with Iran. In conclusion, unlike Israel, this is not an existential war for Europe,” Lopatin said.

“Iran seeks to destroy Israel, not Italy or Germany. Looking at the economic benefits of trade with Iran, it is easier to understand the European approach.”

NATO Faces Unprecedented Strain Over Alliance Expectations

From Washington’s viewpoint, European restraint represents failure to meet alliance obligations rather than strategic caution. The Trump administration has characterized the issue in terms of burden-sharing, arguing that European allies have benefited from American security guarantees while refusing to support US-led efforts in the current conflict.

A White House official, speaking anonymously, told The Media Line: “The president speaks candidly to world leaders when he disagrees with them. This is nothing new.”

More formal communications have made underlying frustrations explicit. Anna Kelly, principal deputy press secretary at the White House Press Office, told The Media Line: “President Trump has made his disappointment with NATO and other allies clear. The United States has thousands of troops stationed in Europe—yet requests to use military bases in order to defend American interests were denied. The president has effectively restored America’s standing on the world stage and strengthened relationships abroad—but he simultaneously will never allow the United States to be treated unfairly and taken advantage of by so-called ‘allies.’”

Olivia Wales, White House assistant press secretary, was more direct. “NATO was tested, and they failed. The United States doesn’t need help from any other country—the blockade is working perfectly, implemented by the greatest Navy in the world, while Iran’s navy is at the bottom of the ocean,” she told The Media Line.

Lopatin said this perception shapes President Trump’s expectations. “Trump really expected Europe to assist him in the conflict with Iran, especially given that the United States has contributed to Europe’s security since the establishment of NATO in 1949, so there is a clear possibility that NATO could weaken or even begin to fall apart,” she said.

Trump-Meloni-Vatican Triangle Creates Unprecedented Diplomatic Crisis

The tensions reached their most public point in an interconnected confrontation involving President Trump, Meloni, and Pope Leo XIV. What might have remained a policy disagreement expanded into symbolic and ideological conflict. The crisis intensified when the president directed criticism not only at Europe generally, but specifically at Meloni and Pope Leo XIV. In an interview with Italian newspaper Corriere della Sera, President Trump responded to Meloni’s condemnation of his papal comments by saying: “She’s unacceptable. She’s unacceptable because she doesn’t mind that Iran has a nuclear weapon and would blow up Italy in two minutes if they had the chance.”

His statements about Pope Leo were equally direct. The Washington Post reported that President Trump called the pope “WEAK on crime” and “terrible for Foreign Policy,” and said he was “not a fan of Pope Leo.” It also reported that the US president posted an AI-generated image depicting himself in a Jesus-like pose alongside the American flag. Reuters and AP both reported that the clash intensified after Pope Leo condemned the president’s threat against Iran as “truly unacceptable” and continued to insist on a message of peace and dialogue.

Vice President JD Vance then added another dimension to the dispute. Speaking on Fox News and at a Turning Point USA event, he said it would be “best for the Vatican to stick to matters of morality” and “let the president of the United States stick to dictating American public policy.” He also said it was “very, very important for the pope to be careful when he talks about matters of theology.” AP separately reported that Leo, while avoiding direct confrontation, continued speaking about peace, dialogue, and unity across religious and political differences.

Meloni’s response to the US president was politically significant because it marked a rare public break with President Trump, saying that Italy will always be a partner of the US but not its “subject,” also siding firmly with the pope. This mattered not only because Italy hosts the Vatican, but because Meloni had been treated as one of President Trump’s closest ideological partners in Europe. She was the only EU leader invited to the president’s second inauguration and had been widely regarded as his key European ally.

Goretti said the rupture was predictable. “The only gluing element between the right-wing and European nationalists like Meloni is an ideological glue, but if you look at the concrete interests, they are divergent, so in any case, this relationship would have been tested in the long run,” he said.

He added: “Returning to the theme of the Trump attacks on the pope, the first response of Giorgia Meloni was a very generic response to the limits of ambiguity, not to have a direct confrontation with Trump, but after a few hours she had to address this again and condemn what had been said.”

Netanyahu Frames European Position as Moral Failure

Benjamin Netanyahu’s Holocaust Remembrance Day speech connects to this broader narrative because it demonstrates how Israeli leadership now characterizes European hesitation as moral decline rather than prudent strategy. In his address at the official opening ceremony for Holocaust Martyrs’ and Heroes’ Remembrance Day, Netanyahu said Europe today was suffering from “deep moral weakness” and was “losing control over its identity, its values and its commitment to protect civilization from barbarism.” He said Europe had “forgotten so much since the Holocaust” and that Israel, alongside the United States and other allies, was defending not only itself but “the entire world.”

These comments are not casual rhetoric. They represent an attempt to place current European criticism of Israel—whether regarding Lebanon, Gaza, or the Iran conflict—within a much broader historical condemnation. In Netanyahu’s framework, Europe has not simply chosen different strategy; it has failed a civilizational test.

This framing reflects fundamental divergence in conflict perception. Lopatin said that was the core meaning of Netanyahu’s speech. “Iran seeks to destroy Israel, not Europe; this is the meaning behind the speech of Netanyahu,” she said.

Vatican’s Unique Role in International Politics Under Pressure

The dispute with the Vatican extends beyond typical Trump controversies. It matters because the Holy See maintains a distinctive position in international politics: it remains one of the few actors that can speak in explicitly moral terms while maintaining diplomatic channels across ideological divisions and conflict lines.

Massimo Faggioli, a professor of theology and religious studies at Trinity College Dublin, told The Media Line that President Trump’s approach reflected political self-legitimization. “It is the picture of a presidency that sees itself with a religious function … it is covered with a messianic cloak. Trump believes he is the savior of America, the savior of the Middle East, the savior of the world.”

He added: “It is a salvific vision of himself and therefore does not recognize the moral authority of anyone else who can act on what is being done in the United States.”

By contrast, Faggioli said the Vatican’s role is stabilizing. “The pope is not interested in humiliating the United States or Trump, but in having a more stable and responsible America in its international policy and in respecting democracy and peace,” he said.

Goretti added a geopolitical perspective. “The Vatican … is also an important diplomatic actor … which tends to try to bring conflicts to some kind of business resolution and thus to peace. If you politicize it, … you also burn bridges to those third actors who could help you to find a path to get out of this situation,” he said.

Collectively, these developments indicate broader transformation rather than temporary disruption.

Goretti said the shift is structural. “The US strategic interest … is progressively moving toward the so-called Asia-Pacific. … This means that NATO loses importance. You can have the maximum of values, visions, everything we want, but if the interests are divergent, notoriously, nationalists of different signs tend to clash,” he said.

He added: “In the contemporary world, the transatlantic relationship … is destined to be resized.”

At the same time, he cautioned against viewing the current moment as definitive. “If the day after tomorrow there are again talks in Pakistan and there is some kind of agreement, Trump will go around saying that he defeated Iran and made the most beautiful peace in the world and returns to be on good terms with Meloni as if nothing had happened. So let’s not believe word-for-word what he states in these circumstances,” he said.

The alliances remain formally intact. But their internal balance—between strategy, politics, and legitimacy—is increasingly unstable. The Iran conflict did not create this shift. It exposed it.
