Intervention vs Isolation: Paradoxical Logic in Trumpian Foreign Policy?

What happens when global leadership built on the promise of restraint turns to force? In less than half of his presidential term, Donald Trump reshaped the global stage in ways very few expected. The toppling of leadership in Venezuela and the decapitation of the government of Iran have thrusted the United States back to the centre of global conflict — a drastic transformation of US foreign policy.

Starting in August, the second half of 2025 witnessed a significant buildup of US military forces in the Caribbean. Codenamed Operation Absolute Resolve, the storming of Fort Tiuna in Caracas on 3 January 2026 with the stated aim of arresting Venezuelan President Nicolás Maduro saw him and his wife captured by US forces and flown out of the country to face US federal indictments related to narco-terrorism. 

US aggression did not stop in the Americas. Less than 2 months later, on 28 February 2026, the United States and Israel launched Operation Epic Fury against Iran. Airstrikes targeting the Iranian military, leadership and infrastructure resulted in the death of the Iranian Supreme Leader Ali Khamenei alongside other officials. Iran responded with missile and drone strikes targeting Israeli and US military bases across the Middle East. In subsequent weeks, strikes continued, causing significant damage to American military and Iranian oil infrastructure. As of early April 2026, Iranian strikes have caused over $800 million in damage to US military infrastructure.

These operations raise questions regarding the US’ — specifically, President Trump’s — approach to foreign policy. Predicted to be an isolationist president, as seen through his protectionist US tariff policies, strained relationships with European allies and strict border control, Trump has since demonstrated the unpredictability of his foreign policy directions. Is Trump pivoting to a more interventionist approach from what was promised, or has he always been aiming to retain a large military presence? If so, how can we identify a pattern in this seemingly abstract picture? 

Trump’s promise to American voters

The anti-war sentiment promoted by Trump became one of the most attractive features of his 2024 campaign. It was a direct rebuke of the Biden administration’s posture, which saw billions flowing into Ukraine, constant American entanglement in European affairs and domestic exhaustion from overextension in Middle Eastern affairs. Trump supposedly offered a stop to this constant entanglement in foreign affairs. He promised that his administration would end the Ukraine-Russia war in 24 hours, putting Americans first and above foreign obligations.

The policy frameworks that followed Trump’s return to the White House seemed to follow this premise. The tariff policy was the poster child, an attempt to shift the American domestic market back to American manufacturers. US military aid to Ukraine was frozen, then conditioned, then redirected. The early months of Trump’s return to office brought a systematic withdrawal from the multilateral commitments that had defined American foreign policy since 1945; the US withdrew from 66 international bodies and treaties, including key climate and UN-related organizations, such as the United Nations Framework Convention on Climate Change and the World Health Organization.

There seems to be a coherent logic to it — “America First” in its strictest reading means exactly what it says: the rejection of open-ended alliances, nation-building expeditions and purportedly policing global disorder on other states’ behalf. This was a posture which America is historically used to, from the isolationism of the interwar period to the long history of the realist critique of liberal interventionism. For voters who witnessed the wars in Iraq and Afghanistan burn away trillions of dollars and return nothing, this position was popular. Young conservative voters who helped return Trump to the White House in 2024 were drawn specifically by his promises to avoid foreign wars. 

What the events of 2026 have revealed is that the premise of isolationism was always only half the picture. At the heart of Trumpian foreign policy direction lies a mercantilist logic and a transactional militarism. Trump uses military interventions and alliances to coerce commercial deals rather than develop long-term soft power commitment. This strategy is drastically different from that of former President Joe Biden’s, whose foreign policy was centred around the re-establishment of alliance management and long-term strategic competition, particularly against China. Under Trump, embedding soft power through alliances became less common, and quick pushes using hard power are preferred. Donald Trump treats power transactionally, while Joe Biden treats it institutionally.

One of the major components of this strategy is the bomb and run strategy, where military actions are carried out for a specific short-term goal, leaving vagueness in its aftermath as a form of political leverage. Another component is alliance trading, where alliances can be traded depending on how beneficial they are in a given moment. This strategy explains Trump’s sudden and drastic maneuvers in Iran, Venezuela and Mexico; while also explaining the strained relationship with European allies, manifested through various comments on Greenland made in the last several months. 

While this approach in foreign policy appears to be rooted in the “pure” realist understanding of international relations, it rejects Trump’s isolationist promise to American voters.

Trump’s Dramatic Rejection of Isolationism in 2026

Through the final months of 2025, the United States assembled what Trump described as “the largest Armada ever seen in the History of South America” off the Venezuelan coast. A maritime blockade of sanctioned oil tankers was already in place. American strikes on drug boats in the Caribbean had killed over a hundred people between September and December. The reward for Maduro’s arrest had been doubled to fifty million dollars. By the time the airstrikes on Fort Tiuna began, the operation had been months in the making.

Trump’s Mar-a-Lago press conference that afternoon was a case of bravado without blueprint. He announced that Washington would “run” Venezuela in the interim, which is a remarkable statement on its face. He claimed Maduro’s vice president had been sworn in and was “essentially willing to do what we think is necessary”, a characterisation her own government promptly contradicted. He said the operation would “cost nothing” because American oil companies would move in and generate revenues. The details would follow, he suggested. They largely have not, as Trump declined further elaboration and American oil companies provide little details.

The framing of the operation was deliberate and revealing. There was little conventional spin on American “warspeak” employed, no “pre-emptive strike,” no “stabilisation mission.” The administration emphasised that the Venezuela action was a law-enforcement exercise — a criminal extraction backed by military force to serve narco-terrorism indictments. Maduro was not killed either. He was arrested. This distinction mattered to the administration because it allowed the US to act without triggering the full weight of having invaded a sovereign nation. Whether international law accepted that framing is a separate question, but as a mode of political communication, it served a purpose: minimum action, minimum commitment, maximum result. This reflects Trump’s transactional militarism. Framing the operation as a form of law enforcement helped Trump coerce the Venezuelan government into acquiescing to his goals, while avoiding the implication of a broader intervention. 

Weeks later in Iran, the same administration dropped the law-enforcement pretence. When Operation Epic Fury began, the stated objective was not to serve a warrant, but rather to decapitate a government. Supreme Leader Ali Khamenei was killed in the first wave of strikes. Iranian defence officials, IRGC commanders and the intelligence chief were targeted systematically. Trump announced the operation in an eight-minute video uploaded to Truth Social, declaring that the US would “raze” Iran’s missile industry to the ground. Where Venezuela had been dressed as a police action, Iran was presented as what it was: a war of regime change.

What made the timing of the Iran operation so striking was not the strikes themselves, but what preceded them by 24 hours. On 27 February, Oman’s foreign minister had announced that a diplomatic breakthrough was within reach, that Iran had agreed to full IAEA verification and to irreversibly downgrade its enriched uranium stockpile. Talks were expected to resume on 2 March 2026. The US and Israel attacked the following morning. Oman’s minister said afterwards that he was “dismayed” and that “active and serious negotiations” had been undermined. Why would Trump abandon diplomacy if it had not reached its full value? 

This confusion rests on a misunderstanding of the role of diplomacy within this framework. Diplomacy is not an instrument meant to reach a stable agreement, but an informational and strategic phase to reveal opponent’s constraints and willingness to concede. Once information is extracted, the value of continued negotiation declines. In fact, waiting can reduce leverage if it gives the opponent time to regroup and harden their position.

From this view, the strike is not a rejection of diplomatic leverage, but an alternative use of it. The concessions showed the limit of Iran’s compromise, and acting immediately locks in that advantage before it’s gone. The damage to real diplomacy is felt, but within this logic it is an acceptable trade-off for an immediate strategic gain.

Between these two grand episodes, a third one played out more quietly, but belonging to the same logic. On February 22, Mexican armed forces — operating on an intelligence package provided by a newly established US Joint Interagency Task Force-Counter Cartel (JITF-CC) — killed Nemesio “El Mencho” Oseguera, the leader of the Jalisco New Generation Cartel, in a pre-dawn raid in Tapalpa, Jalisco. The White House confirmed the US provided intelligence support. No American boots were on the ground, and the Mexican government was careful in framing the attack as their own. But the pressure that produced it, including the tariff threats made early in his presidency and the explicit warning from the Trump administration that it would conduct a Maduro-style raid inside Mexico and other South American countries if there was no government action, have blurred the line between US-led and US-supported. Cartel retaliation quickly spread throughout the country within hours. The kingpin is dead, the cartel remained intact, but is now shattered violently into competing factions. To the US, the operation achieved its symbols, to shatter and disorganize the cartel, and what followed, again, is not Trump’s problem.

And then there is Greenland, which does not fit the pattern of previous US foreign policy. That is why it matters most. Venezuela, Iran and Mexico are adversaries or pressure points. Greenland is a territory within Denmark; it is a NATO ally. When Trump said in January that it “may be a choice” between acquiring Greenland versus preserving NATO, and when his advisers began posting maps of the island overlaid with the American flag the morning after Maduro’s arrest, European capitals understood something that the administration had not quite said aloud: the same logic of transactional coercion that was being applied to rivals was now being applied to partners.  Denmark’s prime minister said that a US attack on Greenland would end NATO. She was not exaggerating. The Danish Defence Intelligence Service named the US a potential national security threat for the first time in its history. Trump eventually backed down from the most explicit threats, ruling out military action at Davos, but the Carnegie Endowment captured the residue precisely: the episode had “crossed a line that cannot be uncrossed”.

The Consequence of Transactional Militarism

What these four cases share in common is not a world ideology. Trump is not a Wilsonian liberal exporting democracy, nor a cold-war hawk defending rule-based order. He is not, despite his personal branding, a genuine isolationist. What these cases share is a method: force, or its credible threat, applied to a subject whether they are foe or friend, with little intention of dealing with its long-term consequences: a transactional militarism. Venezuela’s governance vacuum, the Iran conflict’s seemingly uncertain continuity, the CJNG’s violent fracture, NATO’s corroded trust. These are not failures of the strategy. They are a feature of it. US Secretary of War Pete Hegseth, when asked to defend the Venezuela Operation, described the Iran war as “the exact opposite of Iraq.” He argued that the US had spent decades purchasing “in blood and got nothing in return economically.” He argued Trump had flipped the script by prioritising military action in exchange for resources and political leverage, without the long-term burden of sustaining or mediating a conflict. This statement in itself is quite remarkable because of how honest it is. It implicitly confirms that the vagueness of all of these conflicts’ purpose is political leverage for the US. Commitment seals a deal. Vagueness extends leverage.

However, this framework cannot easily accommodate allies. A transactional worldview such as this one divides the world into two: the US, who receives leverage, and counterparties. Trump’s threats toward Greenland — while tangible action is fortunately not yet a reality — have visibly eroded alliances. Putting the same coercive logic to Greenland has fractured the post-war alliance architecture decades in the making. 

The beneficiaries of this are not difficult to identify. Russian Foreign Minister Sergei Lavrov noted the transatlantic rift with visible satisfaction. Former Estonian Prime Minister Kaja Kallas observed that Beijing and Moscow were “probably celebrating.” Every fracture in NATO is a margin of maneuver recovered by the adversaries the alliance was built to deter.

Open Verdict

Whether this transactional militarism framework works is quite an open question. The short-term benefits for the American is obvious: leaders of adversary governments are effectively decapitated — Maduro has been arrested and Khamenei assassinated, Iran’s nuclear program appears deferred and one of the biggest narco bosses in a generation is dead. 

But the political implications do not end there. A new precedent is now in place following Venezuela: that a large country may indict and militarily extract the leader of a smaller one. US Senator Mark Warner asked an important question back in January: what prevents China from claiming the same authority over Taiwan’s leadership? Or Russia over Ukraine? The administration did not answer. The Venezuelan government is experiencing a vacuum of leadership despite the Venezuelan vice-president having been sworn in as an interim president; as with the CJNG, who has reacted with violent fragmentation and leadership transition. The Iran war is still ongoing, with a fragile ceasefire currently in place following 40 days of fighting. High-stakes negotiations in Pakistan between the US and Iran have recently stalled without any long-term agreement. 

The full shape of what Trump is building — or dismantling — is not yet visible. The Maduro trial continues, the continuity of the Venezuelan government is still uncertain and the peace talks in Pakistan have recently failed. The 2026 NATO summit will be the first formal test of whether the alliance, or in a sense, the global order, can hold its form under the strain of distrust caused by the US and the precedent they have set. Will it demonstrate its ability for self-reparation or further its destruction? These are the episodes that will reveal whether what we have witnessed in the first months of 2026 will be perceived as a permanent doctrine or the temporary misconduct of an individual. Either way, it is remaking the world in ways that we cannot map just yet.
