Much talked about, European defence is basically the expression of an ambition within the wider framework of the building of the European Union. It can take pride in some tangible achievements, notably in the field, and it has led to some industrial collaboration. None the less, it cannot be considered as a fixed star in the firmament since it is constantly evolving within the dynamic perspective which is Europe. Providing that some institutional uncertainties can be resolved, and that complementarity with NATO acquires real meaning, it can only become stronger, based on what is already in place and on the contribution it can make to the peace and security of the Continent.
