Senator Ryan asked about extending the Petersberg Tasks and the clarification of competencies. No major extension is being proposed to the Petersberg Tasks. There is, in a sense, a clarification. The Petersberg Tasks were formulated before international terrorism was seen as a threat and before it emerged on 11 September 2001 in the United States. The idea is to see how the Petersberg Tasks can cope with a situation where states increasingly have to protect themselves against that type of attack and what role the Union plays in that area. This is where the concept of a solidarity clause arises. It is not the same as a mutual defence clause. If, for example, the UK believes there is a threat of biological attack and Ireland has a service, be it medical or otherwise, that could be of assistance, we would make it available. There would be other implications as well. However, it is an under-developed idea at present.
