European leaders from France, Germany, and the United Kingdom have maintained a consistent emphasis on defensive measures and diplomatic engagement since the February 2026 onset of U.S.-Israel military operations against Iran. Joint statements have condemned Iranian missile and drone attacks on regional allies while pledging only proportionate responses to protect navigation in the Strait of Hormuz and safeguard personnel, with deployments limited to naval assets and support for allied operations. Ongoing U.S.-Iran ceasefire talks and nuclear negotiations through April have reinforced Europe's preference for de-escalation over direct strikes, reflecting institutional constraints and domestic political realities. This positioning underpins trader consensus favoring no independent action by the June 30 deadline. A major Iranian attack on European forces or assets could still prompt a limited defensive response.
