Ya...It's anyones guess really. WEU does look interesting though:
----------------------------------------------------------------------------------------------------------------------------------
Set up in 1948 by the Treaty of Brussels, the WEU is a European organisation for the purposes of cooperation on defence and security. It consists of 28 countries with four different statuses: Member States, Associate Members, Observers and Associate Partners. Of the EU-15 countries,
ten are full Member States, while the remaining five - Austria, Denmark, Finland, Ireland and Sweden - have observer status. The six Associate Members are the Czech Republic, Hungary, Iceland, Norway, Poland and Turkey, and there are seven Associate Partners: Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia and Slovenia.
In the Treaty of Amsterdam the WEU was defined as an integral part of the development of the Union because it
gave the EU operational capability in the field of defence. However, the paragraph concerned was deleted by the Treaty of Nice.
The WEU did indeed play a major role in the first Petersberg tasks, such as the
police detachment in Mostar or cooperation with the police in Albania. However, it now seems to have abandoned that role in favour of
developing the Union's own structures and capabilities in the sphere of the European security and defence policy (ESDP).
The transfer of the WEU's operational capabilities to the Union attests to this. The WEU's subsidiary bodies, the
Security Studies Institute and the Satellite Centre, were hived off to the Union on 1 January 2002. The Treaty of Nice also deleted from the Treaty on European Union a number of provisions concerning relations between the WEU and the Union.
Collective defence, a primary responsibility of the WEU, now falls within the North Atlantic Treaty Organisation's (NATO) sphere of competence.

It does seem it's primarily concerned with policeing and "defence".
