Trump, Bolton and Iran: The Evolution of a Confrontational Policy

Saturday 14 March 2026

The relationship between Donald Trump’s Iran policy and the ideas of his first-term National Security Adviser, John Bolton, is a study in paradox. During Trump’s first presidency (2017–2021), Bolton was widely regarded as the most hawkish voice in Washington on Iran, advocating regime change and military action against the Islamic Republic. Yet Trump repeatedly resisted Bolton’s most extreme proposals. In his second presidency, however, events appear to have taken a curious turn. Trump’s current approach to Iran, culminating in open military conflict in early 2026, seems in certain respects to have gone well beyond what Bolton himself had publicly advocated.

This apparent reversal illustrates a broader theme in Trump’s foreign policy: a mixture of rhetorical extremity, strategic improvisation and personal instinct that often sits uneasily alongside the structured doctrines of traditional national security officials. The story of Trump and Iran, across two presidencies, therefore offers a revealing insight into how American foreign policy is shaped not merely by ideology but by personality, circumstance and the changing architecture of presidential power.

Bolton’s worldview

John Bolton entered the Trump administration in April 2018 with one of the clearest strategic visions of any American policymaker regarding Iran. A long-time neoconservative figure, he had argued for years that the Islamic Republic represented an irreconcilable threat to American interests and that diplomatic accommodation was futile.

Bolton’s preferred strategy had three principal elements.

First, the United States should withdraw from the Joint Comprehensive Plan of Action (JCPOA), the nuclear agreement negotiated by the Obama administration in 2015.

Secondly, Washington should impose maximal economic pressure designed to collapse Iran’s economy and weaken the clerical regime.

Thirdly, the United States should actively pursue regime change in Tehran, either through internal uprising or military force.

The first of these objectives Trump readily embraced. In May 2018 he withdrew the United States from the JCPOA and launched what became known as the “maximum pressure” campaign, imposing sweeping sanctions aimed at reducing Iran’s oil exports to zero and forcing Tehran back to the negotiating table. 

Yet Bolton soon discovered that Trump’s motivations were not identical to his own. Bolton saw sanctions as a step towards regime change. Trump saw them primarily as leverage to secure a new deal.

This distinction would prove decisive.

Trump’s first-term restraint

Despite the bellicose rhetoric that often accompanied his statements on Iran, Trump demonstrated a repeated reluctance to initiate a large-scale war.

The clearest example occurred in June 2019. After Iran shot down an American surveillance drone over the Persian Gulf, senior advisers including Bolton reportedly recommended a retaliatory strike on Iranian targets. Trump initially approved the operation but cancelled it shortly before launch.

The episode revealed the fundamental difference between Trump and his hawkish advisers. Bolton viewed military action as an inevitable stage in confronting Iran. Trump, by contrast, feared being drawn into a Middle Eastern war that would contradict his political narrative of ending “endless wars”.

Even Bolton himself later suggested that Trump was often reluctant to pursue decisive action against Iran, believing the president possessed a strong instinct for dramatic rhetoric followed by attempts at negotiation. 

Trump’s behaviour elsewhere reinforced this pattern. His diplomacy with North Korea followed a similar trajectory: intense threats followed by unexpected summits and personal diplomacy.

In short, during the first Trump presidency the most aggressive strategic ideas within the administration often came not from the president himself but from advisers such as Bolton and Secretary of State Mike Pompeo.

The break with Bolton

Bolton’s tenure in the White House ended abruptly in September 2019 after a series of policy disagreements. Iran was among the most significant of these disputes.

Bolton was deeply sceptical of Trump’s interest in negotiating directly with Tehran. Trump, however, repeatedly suggested that Iran’s leadership should return to talks and hinted at the possibility of a new nuclear agreement.

Bolton’s departure symbolised the triumph of Trump’s personal diplomacy over the more doctrinal approach of traditional national security hawks.

At the time, many observers concluded that Trump’s Iran policy would remain essentially coercive but ultimately transactional: sanctions and threats designed to produce negotiations rather than war.

The second presidency: a different environment

Trump’s second presidency has unfolded in a markedly different geopolitical and institutional context.

The Middle East itself has changed profoundly since 2021. Iranian regional proxies have been weakened by successive conflicts, particularly following Israel’s wars with Hamas and Hezbollah. As a result Iran has appeared more strategically vulnerable than at any time in decades. 

At the same time the composition of Trump’s national security team has shifted. Analysts have noted that the second administration contains fewer independent-minded figures willing to challenge the president’s instincts. 

Former officials from the first administration have argued that this change has significantly altered Trump’s decision-making environment. Without advisers willing to question his assumptions, policy debates within the White House have become narrower and more personalised.

Bolton himself has suggested that the principal difference between the two presidencies is that senior officials are now less likely to tell Trump that he may be mistaken. 

From maximum pressure to war

Trump initially revived the same strategic framework he had employed during his first presidency: the restoration of maximum pressure sanctions combined with demands for a new nuclear agreement. 

However the policy gradually escalated. By early 2026 the United States had deployed large military forces to the region and launched extensive strikes against Iranian military infrastructure.

The resulting conflict has been characterised by large-scale aerial bombardment and attacks on Iran’s missile capabilities, air defence systems and naval assets. According to Trump’s own statements, thousands of targets have been struck and much of Iran’s military capacity has been severely degraded. 

In public remarks the president has described the campaign as a short, decisive operation designed to neutralise Iran’s strategic threat.

Such actions go significantly further than the policy pursued during his first presidency. They also appear, in certain respects, to exceed Bolton’s earlier proposals, which tended to emphasise regime destabilisation and internal pressure rather than a large-scale direct war.

Bolton’s critique of the new strategy

Ironically Bolton himself has been among the critics of the current approach.

His objections do not stem from opposition to confronting Iran but from scepticism about the strategic coherence of Trump’s decisions. Bolton has repeatedly argued that the president does not pursue policy through a clearly defined strategic framework, instead responding impulsively to events.

In Bolton’s view the problem is not excessive aggression but insufficient planning. Military strikes without a clear long-term strategy risk destabilising Iran without producing a stable alternative.

In particular, Bolton has emphasised the importance of exploiting divisions within Iran’s security apparatus, especially between the Islamic Revolutionary Guard Corps and the regular army. Such political engineering, he argues, would be necessary for successful regime change.

Whether this strategy would work is uncertain, but it illustrates the difference between Bolton’s methodical approach and Trump’s more improvisational style.

Trump beyond Bolton?

The paradox of Trump’s second-term Iran policy is therefore striking.

During the first presidency Bolton represented the maximalist position and Trump acted as a restraining force. In the second presidency the situation appears partially reversed: Trump has embarked upon a military confrontation that many of his former advisers regard as strategically unfocused.

This does not mean that Trump has adopted Bolton’s ideology. In fact the opposite may be true. Bolton’s worldview is rooted in a coherent, if controversial, strategic doctrine derived from decades of American conservative foreign policy thinking.

Trump’s approach is less ideological and more personal. It reflects his belief in dramatic demonstrations of power followed by negotiations, a pattern that has appeared repeatedly in his diplomacy.

The difference lies in the scale of the demonstration. In the current conflict with Iran that demonstration has become extraordinarily large.

Trump and Bolton, different sides of a coin

The story of Trump and Bolton illustrates a broader transformation in American foreign policy during the past decade. Traditional strategic doctrines, whether interventionist or isolationist, have increasingly given way to a more personalised style of decision-making centred on the president himself.

Bolton entered the White House believing he could guide Trump towards a long-standing neoconservative objective: the overthrow of the Iranian regime. Instead he discovered that Trump viewed foreign policy as a series of tactical confrontations rather than a structured strategic campaign.

Yet history has produced an unexpected twist. In his second presidency Trump has moved further towards direct confrontation with Iran than Bolton was ever able to persuade him to go.

Whether this represents the culmination of Bolton’s long campaign against the Islamic Republic, or the beginning of a far more unpredictable conflict shaped by Trump’s instinctive style of leadership, remains an open question.

What is certain is that the relationship between the two men has left a lasting imprint on the trajectory of American policy towards Iran.
