WASHINGTON - A growing rift between the United States and its traditional allies is reshaping global diplomacy, as President Donald Trump faces mounting criticism over his confrontational approach to the Iran conflict, according to a new analysis by CNN.

What began as a regional war is rapidly turning into a broader political and economic challenge for US allies, many of whom are struggling to balance Washington’s demands with domestic opposition to the conflict.

Leaders across Europe and Asia, many of whom initially sought to maintain close ties with Trump, are now distancing themselves, citing both political and economic fallout from the war.

British Prime Minister Keir Starmer has openly expressed frustration over rising energy costs linked to the conflict, while Italian Prime Minister Giorgia Meloni described Trump’s criticism of Pope Leo XIV as “unacceptable,” signaling a sharp shift in tone from previously supportive leaders.

The analysis suggests that such reactions reflect not only disagreement with US foreign policy but also growing domestic pressure, as voters in allied countries increasingly oppose involvement in the Iran war.

The economic consequences of the conflict are amplifying tensions. The International Monetary Fund has warned that global growth could slow to 2.5% this year, down from 3.4% in 2025, with energy-dependent economies particularly vulnerable.

Countries such as Japan and the UK -- both heavily reliant on Middle Eastern energy -- are facing rising costs and economic uncertainty, placing additional strain on their governments.

Japanese Prime Minister Sanae Takaichi, who recently took office, is already grappling with economic headwinds linked to higher shipping and energy prices.

- Political Backlash Against Trump

Trump’s assertive rhetoric and unilateral policies are also reshaping political landscapes in allied nations.

In Canada, Prime Minister Mark Carney has consolidated power on a platform partly defined by resistance to Trump’s policies, following tensions over sovereignty and trade.

Meanwhile, in Europe, the defeat of Hungarian leader Viktor Orbán -- long seen as aligned with Trump-style populism -- signals a broader shift, with leaders increasingly wary of close association with the US president.

- NATO and Strategic Divisions

Trump policies also exposed deeper fractures within the transatlantic alliance, particularly around NATO.

Trump’s criticism of allies for not supporting US efforts -- such as calls for military involvement in securing the Strait of Hormuz -- has highlighted both political reluctance and declining military capabilities among European nations.

Analysts say years of defense cuts have left many NATO members unable to meet US expectations, even if political will existed.

The CNN analysis argues that Trump’s reliance on pressure tactics -- including threats, tariffs, and military moves -- may be eroding the very alliances that have underpinned US global influence for decades.

Public opinion data also reflects the divide, with surveys showing low approval ratings for Trump across many allied countries, further limiting their leaders’ willingness to align closely with Washington.

At the same time, the White House appears committed to a strategy centered on unilateral power, viewing alliances less as partnerships and more as instruments to advance US interests.

Despite growing tensions, allied leaders face constraints in distancing themselves completely from the United States, given longstanding security and economic ties.

The paradox, analysts note, is that while Trump’s policies are pushing allies away politically, their dependence on US military support-- particularly under NATO -- prevents a full rupture.

As the Iran conflict continues and diplomatic efforts struggle to gain traction, the widening gap between Washington and its allies could have lasting implications for global order.

For now, the analysis concludes, Trump’s approach risks leaving the United States increasingly isolated -- at a time when coordinated international action may be most needed to prevent further escalation in the Middle East.
