I understand the Belgian authorities have yet to make any formal announcements regarding their EU presidency work programme in the security and defence area. I am not aware of any current proposal to integrate the Western European Union into the EU.
At the time of the Treaty of Amsterdam, it was envisaged that the Western European Union would play a key role in the security and defence area. Article 17 of that treaty evoked the possibility of a future merger of the EU and Western European Union. However, with the enhancement of the EU's capabilities in the area of humanitarian and crisis management tasks, through the European security and defence policy, the role of the Western European Union has diminished. In effect, the issue of the possible integration of the Western European Union into the EU has now been left aside. In the Treaty of Nice, the relevant clauses regarding a possible future EU-WEU merger have now been deleted.
