• UAE and Qatar are actively lobbying allies to persuade the Trump administration to end the escalating US-Iran military conflict, though prospects for near-term settlement remain limited.
  • Both Gulf states have condemned Iran's missile strikes while expressing concerns about the broader conflict, with the UAE noting Iran's unresponsiveness to GCC diplomacy.
  • Mediation efforts are severely constrained as Oman and Qatar, key mediators, have experienced Israeli strikes during negotiations, making further involvement unappealing.

Diplomatic Maneuvers Amid Military Escalation

In the wake of a large-scale US-Israel military operation against Iran that intensified in late February 2026, the UAE and Qatar are engaged in behind-the-scenes diplomatic efforts to address the conflict, according to sources familiar with the matter. Trump has indicated the bombing campaign "could last for weeks" and called for Iranian leadership to capitulate following the killing of Supreme Leader Ayatollah Khamenei, but Iran's security chief has ruled out negotiations, complicating peace initiatives.

Both Gulf states find themselves in a precarious position. The UAE, which has invested heavily in building stable relations with Tehran through growing trade and renewed diplomatic ties, strongly opposed Iran's attempt to "regionalize the conflict," with diplomatic adviser Anwar Gargash calling the approach "irrational." Qatar has not directly joined offensive actions but stated it has the "right to respond," leaving its options open regarding potential diplomatic or defensive measures. Efforts to reach UAE and Qatari officials for comment were not immediately successful.

Mediation Challenges and Future Outlook

A critical obstacle to peace efforts is that mediators Oman and Qatar now believe mediation itself has increased their insecurity, after experiencing Israeli strikes while serving as intermediaries. This has made mediation involving Iran and Israel "unappealing" going forward, according to regional analysts. Earlier negotiations in early February 2026 showed some promise, with Oman claiming potential for a breakthrough on uranium stockpiling, but Trump expressed dissatisfaction with Iran's refusal to dismantle its nuclear program entirely.

With the Supreme Leader reportedly deceased and Iran's security establishment ruling out negotiations, the viability of renewed diplomatic efforts appears severely constrained. Iranian negotiators historically approached talks methodically through multiple rounds, a strategy poorly suited to Trump's demand for rapid capitulation, further dimming prospects for a swift resolution. As the conflict drags on, Gulf states are balancing condemnation of Iran's actions with fears of broader regional destabilization, a delicate dance that underscores the complexities of Middle East diplomacy in a volatile era.
