EU in Kosovo

The EU attempts to justify its activities in Kosovo with a number of Press Releases linked from here. I can so far find no reference to the legal basis for such adventurism. Only the Treaty of Nice is presently valid for the EU's activities. Would the World Trade Organisation be entitled to enter say Leicester or Bradford should a large section of the population eg Pakistani decide to opt for independence due to disappointment over the election situation in their own home country one is tempted to speculate. I quote two particular paragraphs of the Preamble to the Nice Treaty, the governing LAW for the EU: RECALLING the historic importance of the ending of the division of the European continent and the need to create firm bases for the construction of the future Europe, CONFIRMING their attachment to the principles of liberty, democracy and respect for human rights and fundamental freedoms and of the ruleof law, Involvement in Kosovo can only have a detrimental affect on both areas as far as I can tell. Reportedly the EU member states are not even agreed among themselves on the Kosovo issue so how can the EU separately take a position? The EU Commission is out of control as apparently is the Council!
