The European Union is considering extending its mutual defense clause to Ukraine even before the country becomes a full member.
According to sources cited by The Economist, some EU countries are against fast-tracking Ukraine’s full membership. However, there is general agreement on offering Ukraine alternative forms of cooperation, such as observer status in EU institutions and in the Council of the EU without voting rights.
Meanwhile, European countries are open to invoking the EU’s mutual defense clause, Article 42.7 of the Treaty on European Union, in relation to Ukraine. This clause is similar to NATO’s Article 5, which requires members to assist a country under attack.
One source said EU officials were asked to study this idea during a recent summit in Cyprus.
The proposal is mainly supported by countries concerned about the risk of possible Russian aggression against Europe. In that scenario, they see Ukraine as a strong partner due to its large, experienced army and its advanced capabilities in drones and artificial intelligence.
Article 42.7 of the EU
Article 42.7 of the Treaty on European Union is a political commitment of solidarity, without a unified command structure.
NATO, by contrast, has a more integrated military structure and coordinated defense planning.
The only known case of its activation was by France in 2015 following the Paris terrorist attacks. At that time, other EU countries provided support, including through military missions and operations.
If similar guarantees were extended to Ukraine, it would mean that EU countries would be legally obliged to respond to any potential aggression against it – even without full EU membership.
