How Trump Can Win Back Allies and Rejuvenate US Diplomacy on Iran
How Trump can win back allies - As tensions over Iran reached a boiling point, Secretary of State Marco Rubio’s recent trip to Abu Dhabi highlighted a critical shift in American strategy. During his June 23 visit to the Gulf, Rubio outlined the administration’s renewed focus on engaging regional partners, emphasizing the importance of incorporating their perspectives into all strategic decisions. This statement, though welcomed, underscored a long-standing issue in Trump’s foreign policy: the sidelining of allies during the initial stages of the Iran conflict.
“We want to make sure their views are taken into account in every decision that we make,” Rubio told reporters upon arriving in Abu Dhabi. His words, while hopeful, revealed a pattern of delayed diplomatic outreach that had left many allies feeling abandoned.
The Gulf states, particularly those in the direct path of Iranian retaliation, bore the brunt of the war’s economic and physical consequences. Critical infrastructure—including energy facilities, transportation networks, and tourist attractions—was targeted, causing widespread disruption. The closure of the Strait of Hormuz, a vital maritime chokepoint, sent shockwaves through global markets, driving oil prices to unprecedented heights and straining the economies of Europe and Asia.
Despite these challenges, the Trump administration had not prioritized alliance-building prior to the conflict. Instead, it had acted unilaterally, dismissing warnings from Gulf nations about the potential for Iranian strikes. Countries that had long-standing partnerships with the U.S. were left to confront the fallout alone, with no top officials from Washington present to offer solidarity or guidance.
This lack of consultation became a defining flaw in the U.S. approach to the Iran war. While Rubio’s efforts in June signaled progress, they also exposed a deeper problem: the administration’s failure to recognize the value of alliances before the conflict escalated. The memorandum of understanding that concluded the war, while achieving a symbolic victory, left many unanswered questions about Iran’s long-term commitments. The document, though securing the reopening of Hormuz, failed to address the concerns of nations eager to restore pre-war conditions.
Trump’s foreign policy had long been characterized by a disdain for diplomatic engagement, favoring assertive action over consensus-building. The Iran war exemplified this trend, with the U.S. relying on military force rather than coalition-building. By the time the conflict reached its peak, the administration had to scramble to reengage its partners, only to find them skeptical or reluctant to support further interventions.
The aftermath of the war revealed the consequences of this approach. NATO allies, once steadfast in their commitment to U.S. leadership, hesitated to commit resources to reopening Hormuz. Years of economic pressure, trade disputes, and public criticism had eroded trust, leaving the U.S. isolated when it needed support most. The irony was stark: the same countries that had warned of Iranian retaliation were now hesitant to back the U.S. in its own war efforts.
Rebuilding alliances will require more than rhetorical gestures. It demands a commitment to sustained engagement, mutual respect, and shared objectives. Trump’s critics argue that alliances are not mere tools to be activated in crisis but relationships cultivated through years of collaboration and trust. The administration’s unilateral approach, which prioritized speed over diplomacy, had left many partners feeling like pawns rather than partners.
Two key areas remain where U.S. diplomacy can still make a meaningful impact. First, the reestablishment of the Strait of Hormuz. While the memorandum of understanding pledged Iran to reopen the strait, it left its governance ambiguous. Most nations, including those in Europe and Asia, seek a return to the status quo, with no Iranian fees or regulatory controls imposed. Leveraging this widespread consensus could help isolate Iran and reaffirm U.S. leadership. A binding United Nations Security Council resolution, backed by China and Russia, could be a powerful tool to enforce these terms.
Second, the ongoing negotiations on Iran’s nuclear program. The administration had ceded significant economic leverage before these talks even began, weakening its position in critical discussions. Rebuilding this power requires assembling a broad coalition around a common definition of a fair agreement. The goal—limiting Iran’s enriched uranium stockpiles, imposing permanent restrictions on enrichment, and ending Tehran’s support for proxy forces—aligns with U.S. interests and those of its allies. Success here would not only stabilize the region but also restore credibility to American diplomacy.
The Iran war served as a stark reminder of the importance of diplomacy in shaping global outcomes. When the U.S. stripped away its diplomatic tools, it left a vacuum that allowed Iran to dictate terms in its own favor. The administration’s belated recognition of this reality is a step forward, but it also highlights the need for a more proactive approach to alliance-building. If Trump is to reclaim his standing as a global leader, he must demonstrate that the U.S. is willing to invest in long-term relationships rather than treating them as temporary allies.
Ultimately, the war underscored a fundamental truth: American power is most effective when it is backed by a coalition of willing partners. By ignoring the warnings of Gulf states and European allies, the Trump administration had sown the seeds of its own vulnerability. Now, with the conflict over and the stakes high, the U.S. must prove that it can rebuild trust and reassert its role as a reliable partner in the global arena. Whether it can do so will depend on its ability to transform rhetoric into action and prioritize diplomacy over dominance.
As the dust settles, the lessons of the Iran war are clear. Alliances are not just a network of countries but a foundation of international influence. The U.S. cannot afford to treat them as expendable in times of crisis. If it is to avoid future isolation, it must embrace the principles of consultation, collaboration, and respect that define effective statecraft. The path forward for Trump and his team is not easy, but it is essential—for the sake of American credibility and global stability.
