Sadly, EU institutions in the area of direct foreign policy have been continuously undermined - mostly by French and UK governments who wanted "their hands free", but also by tactical US moves to ensure NATO would stay relevant. There are real contrasts in outlook among member states when it comes to larger geopolitical issues (even extremely close to home, like Lybia and Turkey), coupled with a general unwillingness, among most member states, to engage in dangerous (and expensive) geopolitical games. That makes it hard to formulate robust action plans beyond the usual platitudes. There is no EU military force yet for that same reason, in practice.
The hope is that long-term economic integration will progressively reduce these problems, by turning "national spheres of influence" into "European spheres of influence". But at the moment, EU foreign-policy mechanisms (and appointees...) are fairly weak. We'll see what happens after we digest the loss of Britain, which was an extremely vocal (and followed / respected) member on these topics. Maybe we'll finally grow up a bit.
