Dr. Farid Mirbagheri, Senior Scholar Middle East, writes on the divergence of US and UK policy on Iran. The key contributions of the article are the following

1. Growing divide between the US and UK weakens Western unity
The article argues that there is a significant and unusual gap between Washington and London on Iran policy, even wider than disagreements seen during the Ukraine war. This lack of coordination undermines the coherence and credibility of the Western alliance.

2. Disunity risks Europe’s strategic position and influence
European hesitation to fully support US actions, such as denying airspace access, signals deeper fractures. Combined with economic strain from Ukraine, this weakens Europe’s global standing and its ability to act as a unified strategic actor.

3. Historical US–UK alignment was key, and its absence now delays outcomes in Iran
The article highlights that major developments in Iran historically occurred when London and Washington acted together. Today’s lack of alignment is seen as slowing or obstructing political change and effective policy outcomes regarding Iran.
