Alliances

European Union

Major economic bloc, JCPOA party, and the principal Western voice for diplomatic preservation of the nuclear architecture.

Role in conflict

The EU, especially through the E3 (France, Germany, UK before Brexit), has been a consistent voice for preserving the JCPOA framework and a major source of humanitarian funding to the region. Its leverage is primarily economic — Iranian access to European markets, banking, and energy infrastructure — but its political leverage has narrowed since 2018.
