As tensions simmer in the Middle East, leaders from Gulf states have sounded a stark warning to their US allies: Iran's relentless expansion through proxy groups remains an acute threat to regional stability, despite the recently inked deal between Tehran and Washington.
A senior US official has acknowledged these "concrete concerns", insisting that any lasting agreement must not only rein in Iran's nuclear programme but also bring an end to its clandestine backing for militant organisations like Hamas, Hezbollah, Shia militias in Iraq, and the Houthi rebels in Yemen. Yet analysts and Western security experts predict that Tehran will bolster support for these groups, capitalising on the strategic advantages gleaned from recent regional conflicts.
Hezbollah, a decades-old Iranian client with roots in Lebanon, remains a linchpin of Iran's proxy network. Despite suffering significant losses during protracted battles in 2024 and 2025, Tehran has demonstrated an unwavering commitment to the organisation. Experts posit that Iran views this as a temporary setback, believing Hezbollah will regroup, and that rebuilding these proxies is crucial for the Iranian Revolutionary Guards.
The Houthi rebels in Yemen have showcased their capacity to target Israel and threaten international shipping in the Red Sea, albeit with a degree of independence from their Iranian patrons. Similarly, Shia militias in Iraq, nurtured by Iran for over two decades, have flexed their capabilities during the conflict, claiming responsibility for drone and rocket attacks on US assets and targeting Kuwait, though they did not mobilise their full offensive arsenal.
The UK Government remains vigilant regarding regional developments, updating travel advice frequently for countries in the affected area. The ongoing tensions and potential proxy activity pose risks to regional security, which could impact international trade routes – particularly through the Red Sea – crucial for global shipping. Britain has consistently advocated for de-escalation in the region and supports diplomatic efforts to curb destabilising activities.
The implications for the UK include disruptions to global supply chains, potentially affecting the cost of goods and energy. British nationals residing or travelling in affected areas are advised to remain cautious, as regional instability could have far-reaching consequences for international trade and security.
