It might not have been the original aim to integrate defence. Nevertheless, it doesn't mean that defence integration should not be done. The aims are changeable; they should be reconsidered and revised, according to requirements and demands of current situations. Few would have imagined how far Europe would come in other areas such as freedom of movement or the creation of a European Common Foreign policy from a mere industrial coalition between few countries. The EDF will be a rationally reasonable step for the EU, considering the advances that the community has made in integration in other areas of policy. To protect all its achievements, to connect its member states, and to provide its citizens with more safety the EU needs a dedicated defence force.
