As a general rule, we always try to find the most economic approach in all our activities. However, when we are dealing with a real operation, such as the one in Libya, it is up to every nation to propose its own contribution. We also need to bear in mind the basic principle of solidarity under NATO: every nation assumes the costs of its contribution. So NATO incurs no additional costs. NATO does not have a fund per se that pays for an operation and that will pay differently, depending on whether the troops come from Canada or Italy, for example.
Each country has to first decide on the merits of the operation; that is what happened in Libya. Twenty-eight countries said that we had to intervene. As sovereign nations, every country then has to decide how it will contribute to the activity. So once again, that is why there were only eight NATO member states that physically contributed to the operation in Libya. But all the member states contributed through the command structure and through some common financial resources that were made available. As to how forces are assigned to an operation, each nation decides what its contribution will be in terms of equipment and the number of people, and it decides on who will bear the costs.
