Even if other countries such as Russia are unwilling to give up their own seats Britain and France have an alternative in the form of joint European Union membership. Both countries are therefore much more likely to agree to lose their seats than Russia w  The member states of the European Union haven’t harmonized their foreign policies so far simply because they have vastly divergent interests in the arena of global power politics. The interests of Germany vis-a-vis Russia are a world apart from France and the UK’s interests, let alone Poland’s. For example in the brief war between Georgia and Russia in 2008 France, Germany and Italy tried to avoid confrontation with Russia while Eastern Europe and Britain demanded a much tougher stance with sanctions. [1] And France and the UK famously took very different positions over the Iraq War, while their different experiences of empire and decolonisation give them a wider international perspective than most other EU states. Handing the EU a single seat does nothing to change those interests, and thus would actually harm every member state’s individual foreign policy interest, instead of furthering it.
