“Treaty of Lisbon. Questions and Answers”. Europea.eu – Will the Treaty create a European army?
No. Military capabilities remain in national hands. The Treaty foresees that Member States can make available civilian and military resources to the Union for the implementation of its Common Security and Defence operations. However, any Member State has the right to oppose such operations and all contributions to them will be always on a voluntary basis.
A group of Member States who are willing and have the necessary capability will be able to undertake disarmament operations, humanitarian and rescue tasks, military advice and peace-keeping tasks. No Member State can be forced to participate in such operations.
