Article 42(7)

Article 42(7) of the Treaty on European Union states that if a European Union (EU) member state is attacked, other EU countries have a duty to assist that state, including providing aid and support. This clause emphasizes collective defense among EU nations, similar to NATO's principle of mutual defense. However, the specifics of the assistance are determined by each member state, meaning they can choose how to respond. This article reflects the EU's commitment to solidarity and security among its member countries, reinforcing the idea that an attack on one is considered an attack on all.
