What Happened to Trump Administration's Iran Policy?

The Trump administration's Iran policy, first implemented during his initial term, marked a dramatic shift from the preceding Obama administration's diplomatic engagement. Central to this policy was the unilateral withdrawal of the United States from the Joint Comprehensive Plan of Action (JCPOA) on May 8, 2018. President Trump criticized the deal for not adequately addressing Iran's ballistic missile program, its regional malign activities, and the sunset clauses on nuclear restrictions, deeming it a 'great embarrassment' that failed to halt Iran's nuclear ambitions. Following the withdrawal, the administration launched a 'maximum pressure' campaign, reimposing and expanding stringent sanctions on Iran's economy, particularly targeting its oil exports, financial sector, and key industries like iron, steel, aluminum, and copper. The stated goal was to force Iran to negotiate a new, broader agreement that would encompass its nuclear program, ballistic missiles, and regional behavior.

In response to the escalating US sanctions, Iran gradually began to breach the limits set by the JCPOA starting in May 2019, increasing its uranium enrichment levels and stockpiles, and reducing cooperation with International Atomic Energy Agency (IAEA) inspections. This period saw heightened tensions, including attacks on oil tankers in the Gulf and the US killing of Iranian General Qassem Soleimani in January 2020, which brought the two nations to the brink of direct conflict. Despite the economic pressure, Iran did not return to the negotiating table on US terms during Trump's first term, and the JCPOA remained in jeopardy.

Upon President Trump's return to the White House in February 2025, the 'maximum pressure' campaign was immediately reinstated and intensified through National Security Presidential Memorandum 2 (NSPM-2). This renewed hardline approach aimed to drive Iran's oil exports to zero and aggressively enforce existing sanctions, citing Iran's funding of terrorist proxies and rapid improvement of nuclear capabilities. The period from late 2025 into 2026 witnessed significant internal unrest in Iran, with nationwide protests violently suppressed by the regime, which the US attributed partly to sanctions-induced economic collapse.

The situation dramatically escalated in June 2025 when the US and Israel launched coordinated military strikes against key Iranian nuclear facilities, including Fordow, Natanz, and Isfahan, following an IAEA finding of Iran's non-compliance with NPT safeguards. These strikes severely damaged Iran's enrichment infrastructure. Despite initial claims of success, tensions continued to mount, culminating in the outbreak of the '2026 Iran War' on February 28, 2026, with US-Israeli airstrikes targeting Iranian officials, including Supreme Leader Ali Khamenei, and military infrastructure. Iran retaliated with missile and drone attacks and by blocking the Strait of Hormuz.

As of August 2026, the conflict has seen a fragile two-week ceasefire in April 2026, which later collapsed in July. While US and Israeli strikes have significantly disrupted Iran's nuclear program, leaving its status unclear due to reduced IAEA access, Iran is reportedly showing signs of attempting to rebuild some facilities. International sanctions remain robust, with the EU designating the IRGC as a terrorist organization in February 2026 and Canada imposing new sanctions in August 2026 for activities in the Strait of Hormuz. Diplomatic efforts to end the war and address Iran's nuclear ambitions are ongoing, with the Trump administration engaging a broader range of European interlocutors, but a comprehensive resolution remains elusive, and the US House is advancing a new sanctions bill.
