EU leaders have requested that officials draft a blueprint detailing how the bloc's previously obscure mutual assistance clause would function, host Cyprus announced at a summit on Friday. This move comes amid growing concerns over the United States' commitment to the NATO military alliance.
Growing Urgency Amid US Skepticism
Worries about President Donald Trump's criticism of NATO for not supporting the war with Iran, along with his earlier threats to seize Greenland from ally Denmark, have heightened the urgency to define the EU's mutual assistance provisions. Cyprus President Nikos Christodoulides stated that EU leaders agreed at a summit in his country on Thursday evening that it was time to flesh out the pact, which is outlined in Article 42.7 of the bloc's core treaty.
"We agreed last night that the European Commission will prepare a blueprint on how we respond in case a member state triggers Article 42.7. There are a number of questions that we need to have an answer to," Christodoulides said.
Article 42.7 vs. NATO's Article 5
Unlike NATO's Article 5 collective defense pact, which is considered the cornerstone of European security, the EU's mutual assistance clause lacks detailed operational plans and military structures. It has been activated only once, by France after Islamist attackers killed 130 people in Paris in 2015. In that instance, member states contributed to EU and international military missions, freeing up France to redeploy its troops.
Cyprus is particularly keen to strengthen Article 42.7 after a drone struck a British air base on the island last month during the Iran war. The country, which currently holds the rotating EU Council presidency, is not a member of NATO.
Balancing EU and NATO Commitments
Some EU countries, however, are anxious to avoid any actions that might suggest they are turning away from NATO and its Article 5 mutual defense pact. "For me it is an absolutely crucial thing that Article 5 is the key of our collective defense and collective security and it will remain so," Lithuania's President Gitanas Nauseda told reporters on Thursday.
Article 42.7 of the Treaty on the European Union states that "if a Member State is the victim of armed aggression on its territory, the other Member States shall have towards it an obligation of aid and assistance by all means in their power." Christodoulides explained that the blueprint would address questions such as which countries would be first to respond and what the needs of the triggering country would be.
EU foreign policy chief Kaja Kallas briefed leaders on ongoing work to flesh out Article 42.7 at the summit, an EU official said. "NATO remains the bedrock of collective defense," said the official, speaking on condition of anonymity. "But the EU has tools available that are complementary to NATO - such as sanctions, financial assistance and humanitarian aid - which could come into play in an Article 42.7 situation."
Kallas' team is drawing up scenarios including hybrid attacks, conventional attacks, and a case in which both Article 42.7 and NATO's Article 5 are triggered in parallel, the official added.
