Observers assess that the ongoing war with Iran is placing sustained pressure on US global influence, while deepening tensions with countries already grappling with the geopolitical and economic fallout of Donald Trump’s second term.
A report published by Politico indicates that this erosion of American power may prove difficult to reverse, particularly as rival powers such as China capitalise on the shifting balance.
According to the report, the conflict is accelerating what some analysts describe as a growing US detachment from the rest of the world, driven by an assertive display of economic and military power, including the use of tariffs and unilateral actions.
An Asian diplomat based in Washington, speaking anonymously, noted that many governments are increasingly fatigued by the instability surrounding the war and concerned about its economic implications. While large scale protests have not materialised, the underlying unease remains significant.
The diplomat added that while a more measured leadership in the future could restore aspects of US credibility, policymakers are now confronting deeper structural questions regarding alliances, including how far they can continue relying on Washington as a dependable partner.
In a clear signal of shifting priorities, Canadian Prime Minister Mark Carney described his country’s economic ties with the United States as vulnerabilities that must be addressed. He emphasised the need for Canada to strengthen its independence, warning against relying on a single external partner amid ongoing instability.
Energy Disruptions and Strategic Realignment
Since the United States and Israel launched military operations against Iran on 28 February, global energy markets have experienced severe disruption. The closure of the Strait of Hormuz and Iranian strikes on regional energy infrastructure have intensified volatility.
Although Washington’s position as a leading oil and gas producer has delivered short term gains, the report suggests these advantages may not be sustainable.
Asian economies, particularly those exposed to energy price fluctuations, have responded by accelerating investments in renewable energy and restarting nuclear power facilities. Some countries have implemented temporary measures such as remote work policies or export restrictions to manage fuel shortages.
In Europe, governments are expanding energy efficiency initiatives, scaling renewable capacity, and promoting electric vehicle adoption to reduce reliance on single source suppliers.
This global transition is increasingly directing attention toward China, which dominates large segments of the solar energy supply chain, controls critical minerals essential for clean energy technologies, and produces competitively priced electric vehicles.
Masato Kanda stated that the objective is not merely to withstand the shock but to leverage the current uncertainty to establish a more resilient and sustainable energy framework.
In contrast, Chris Wright criticised the effectiveness of renewable energy policies in an interview with CNN, asserting that the United States will retain its influence as the world’s largest net exporter of natural gas and a major oil supplier.
Fracturing Alliances and Middle East Calculations
From a military standpoint, the report highlights a departure from previous regional conflicts, where US administrations were able to rally even reluctant allies. In the current scenario, the Trump administration did not provide prior briefings to key European partners and has yet to present a coordinated strategy.
Following the disruption of shipping routes through the Strait of Hormuz, United Kingdom and France convened meetings with allied nations to develop defensive maritime operations independently of the United States. Details regarding timing and force contributions remain under discussion.
Simultaneously, the European Union is exploring mechanisms to strengthen its collective defence framework under Article 42.7, a move interpreted as a response to escalating US unpredictability, including controversial territorial rhetoric regarding Greenland.
Despite these developments, Politico notes that US defence relationships remain deeply embedded and difficult to dismantle. Although Trump has repeatedly threatened withdrawal from NATO, no substantive steps have been taken, and many countries continue to view US military capability as indispensable.
This dynamic was reflected in the launch of major joint military exercises involving the United States and the Philippines, with expected participation from Japan and Canada, widely interpreted as a strategic signal directed at China.
Narrative Warfare and Washington’s Justifications
Diplomatically, internal US State Department cables cited by Politico reveal a growing spread of anti American narratives, with warnings that rival powers are actively exploiting the decline in US credibility.
Trump’s decision to establish a Gaza focused “peace council” has further strained relations with European partners, facing lukewarm reception and outright rejection from Belgium regarding financial support.
In response, US State Department spokesperson Tommy Pigott defended the administration’s actions, stating that they enhance long term global security by preventing Iran from acquiring nuclear weapons.
White House spokesperson Anna Kelly similarly argued that current policies have delivered stronger trade agreements, a position supported by former National Security Council official Alexander Gray, who suggested that the war could generate strategic gains for future US administrations.
