The concept of “flexible realism” gained traction in foreign policy circles as a potential path forward in a world increasingly defined by complexity and uncertainty. Proponents argued it offered a pragmatic alternative to rigid ideological stances, allowing nations to adapt to shifting circumstances and pursue their interests without being constrained by dogma. Although, the escalating tensions between the United States and Iran, particularly during the latter half of the 2020s, exposed the inherent flaws and the false promise of this approach. The pursuit of flexible realism, as practiced by the Trump administration, revealed itself not as a nuanced strategy, but as a foreign policy devoid of consistent principles, driven instead by domestic political considerations and personal impulses.
The core tenet of flexible realism, as it was presented, was the willingness to reassess alliances and adversaries based on immediate strategic calculations. This meant abandoning long-held commitments and embracing transactional relationships. While adaptability is undeniably crucial in international relations, the implementation under the Trump administration lacked the foundational stability of clearly defined national interests. Instead, decisions appeared reactive, often contradicting previous statements and undermining diplomatic efforts. This created a climate of distrust among allies and emboldened adversaries, ultimately increasing instability rather than fostering a more predictable world order.
The Unraveling of the Iran Nuclear Deal
A prime example of flexible realism in action – and its subsequent failures – was the withdrawal of the United States from the Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal, in May 2018. The State Department under President Trump argued the deal was flawed, failing to adequately address Iran’s ballistic missile program and regional activities. The decision, despite objections from European allies – the United Kingdom, France, and Germany – and other international partners, was framed as a necessary step to protect U.S. National security. However, the withdrawal was not accompanied by a clear strategy for containing Iran’s nuclear ambitions, leading to a gradual erosion of the deal’s restrictions and a resurgence of Iran’s nuclear program.
The reimposition of sanctions on Iran, intended to cripple its economy and force renegotiation of the JCPOA, had the opposite effect. Rather than bringing Iran to the negotiating table, it deepened its resolve to develop nuclear capabilities and increased its support for proxy groups in the region. The escalation culminated in a series of attacks on oil tankers in the Persian Gulf in 2019, attributed by the U.S. To Iran, and the downing of a U.S. Drone. The New York Times reported at the time that the incident brought the two countries to the brink of military conflict.
A Pattern of Inconsistency
The Iran case wasn’t an isolated incident. The Trump administration’s approach to North Korea, initially characterized by bellicose rhetoric and threats of military action, abruptly shifted to a series of unprecedented summits with Kim Jong-un. While these meetings generated significant media attention, they yielded little in the way of concrete progress toward denuclearization. Similarly, the administration’s fluctuating stance on China, oscillating between trade wars and appeals for cooperation on issues like North Korea, created uncertainty and undermined long-term strategic planning. This inconsistency wasn’t a sign of flexibility; it was a symptom of a foreign policy driven by short-term political gains and the personal whims of the President.
The Impact on Alliances
Perhaps the most damaging consequence of flexible realism was its erosion of trust with traditional U.S. Allies. The unilateral withdrawal from the JCPOA, the imposition of tariffs on steel and aluminum imports from allied countries, and the questioning of the value of NATO all strained transatlantic relationships. European leaders repeatedly expressed frustration with the unpredictability of U.S. Policy and sought to pursue independent strategies to safeguard their interests. This divergence in approach weakened the collective security architecture that had underpinned global stability for decades. The strain on alliances also extended to the Indo-Pacific region, where allies like Japan and South Korea questioned the reliability of U.S. Security commitments.
The Limits of Pragmatism Without Principles
The experience with flexible realism demonstrates that pragmatism, while valuable, cannot exist in a vacuum. A successful foreign policy requires a clear articulation of national interests, a consistent set of principles, and a commitment to long-term strategic goals. Abandoning these foundations in the name of flexibility ultimately leads to a reactive and incoherent approach that undermines credibility and increases risk. The pursuit of short-term tactical advantages without regard for the broader strategic context can create unintended consequences and exacerbate existing tensions. The escalating crisis with Iran, marked by military escalations and a breakdown in diplomatic efforts, served as a stark warning about the dangers of a foreign policy without a moral compass.
Looking ahead, the Biden administration has signaled its intention to rejoin the JCPOA, albeit with modifications, and to restore traditional alliances. However, the damage done during the previous administration will take time to repair. The long-term implications of the Trump administration’s approach to Iran, and the broader experiment with flexible realism, will continue to shape the geopolitical landscape for years to come. The next major checkpoint will be the outcome of ongoing negotiations with Iran regarding the terms of a potential return to the JCPOA, expected by the end of 2026. Reuters reported in March 2024 that talks are expected to resume shortly.
