External policies of the EU in non proliferation of WMD

External policies of the EU in non proliferation of WMD

Focus not on history part of the policies, but on the external activities, actions and policies of the EU in non proliferation of WMD. Describe the most important policy, why it has more power than the rest or previous. My conclusion is that EU external policies are ineffective, yes they contributed to some changes in neighborhood and other countries, but generally they are ineffective.
