This briefing document presents findings from the latest Opinium / Observer polling series examining UK public attitudes towards the escalating conflict involving the United States, Israel and Iran. The research explores how the British public interprets the conflict, its perceived legitimacy and consequences, and what role, if any, Britain should play.
It covers:
- Public support for or opposition to the US–Israeli military action in Iran, including perceptions of the motives and legality of the intervention.
- How voters interpret the conflict, including responsibility for escalation and views on Iran’s retaliatory strikes.
- Public concern about the wider consequences of the conflict, including impacts on energy supplies, the UK economy, and the risk of Britain being drawn into the conflict.
- What role the British public believes the UK should play, including attitudes towards diplomatic engagement, humanitarian support, and potential military involvement.
- The domestic and geopolitical context surrounding the conflict, including assessments of UK political leaders and longer-term attitudes towards the United States, Israel and Iran.
The findings provide insight into how the British public understands the current conflict, the limits of public support for UK involvement, and how wider shifts in geopolitical trust may be shaping attitudes towards Western military action.
