Until now, the member states of the European Union have never been able to coordinate their foreign policies effectively. This has led to divided positions amongst member states, for example towards Russia, China and other global players, allowing them to play a ‘divide-and-rule’-strategy against European interests. Giving the EU a single seat would give the Member States a clear incentive to harmonize their policies: a coordinated policy can then be expected to actually take effect, instead of it being a supplement to domestic foreign policy. Interests are guided by who decides what the interests are. With a unified voice from a unified external action service and President Europe will be able to define what the interests of the Union as a whole are.
