Britain's medium-power status requires institutional anchoring to exercise influence in a world of continental-scale competitors, but the council establishes that rejoining depends on resolving a fundamental question about British strategic identity that Brexit has sharpened rather than settled.
Thatcher argues that sovereignty once surrendered to supranational institutions requires principled independence, advocating comprehensive bilateral trade agreements over institutional membership. Schmidt counters that Britain's geopolitical vulnerability demands European anchoring, where pooled sovereignty strengthens rather than surrenders national capacity. De Gaulle maintains that Britain's Atlantic orientation makes stable European membership structurally impossible, preferring privileged partnership over institutional fiction. Adenauer contends that rejoining requires Britain to demonstrate that European integration enables rather than constrains effective sovereignty, following the path Germany took after its own strategic failure.
The irreducible split turns on whether British strategic culture can accommodate permanent European commitment, or whether any future membership would remain conditional and reversible when Atlantic alternatives prove more attractive.
