The European Union is preparing its first-ever exercise simulating a member state requesting assistance under the treaty’s mutual aid clause, potentially against Russian aggression.
Article 42.7 of the EU Treaty
The exercise focuses on activating Article 42.7 of the EU Treaty, distinct from Article 5 of the North Atlantic Treaty. This EU clause obligates member states to provide assistance and support to a member experiencing an armed attack, utilizing all available means, without affecting individual national security policies.
First-of-its-Kind Exercise
The European Union is preparing the first-ever exercise where a member state requests support from other countries due to a threat, including potential aggression from Russia, according to Finnish daily “Helsingin Sanomat.”
The scenario involves a member state becoming the target of a massive hybrid attack, serving as preparation for potential Russian aggression. The exercise is scheduled for early May, coinciding with concerns about waning U.S. engagement in NATO.
Limited Prior Activation
The procedure outlined in Article 42.7 has only been invoked once previously, following the terrorist attack in Paris in 2015.
Non-Military Focus & Key Players
The exercise will be conducted at the ministerial level, involving departments of diplomacy and defense, and will not be military in nature. The High Representative of the EU for Foreign Affairs and Security Policy, Kaja Kallas, is responsible for its preparation.
Avoiding Signals of Independence from NATO
Sources cited by “Helsingin Sanomat” describe the exercise as “politically sensitive,” as the EU aims to avoid signaling an ability to defend itself independently of the U.S. or outside the NATO framework. However, the need to define the mutual assistance clause within the EU has grown due to increasing distrust of the U.S. administration under Donald Trump.
The newspaper recalls earlier this year, the EU feared the U.S. might unilaterally annex Greenland, formally belonging to Denmark, potentially through military force.
Calls for a Stronger EU Defense Structure
Former Finnish President Sauli Niinistö, who prepared a 2024 report for the EU on strengthening civil and defense readiness, repeatedly emphasized the strong treaty obligation of EU states to assist one another—potentially even stronger than Article 5 of NATO. He also advocated for developing a common EU defense structure, serving as a “European pillar of the North Atlantic Alliance.”
Finland’s Shift to NATO
Niinistö served as Finland’s head of state from 2012-2024 and, in response to the full-scale Russian invasion of Ukraine in 2023, led Finland’s accession to NATO.
