It was past midnight in Ayia Napa when the EU leaders who had gathered for the first day of the informal European Council in Cyprus began filing out one by one. The handful of journalists still on the premises were waiting for some word on what had actually been said about Article 42.7 of the Treaty on European Union — the mutual assistance clause.
The issue had been forced into the open in March, as everyone will remember, in the immediate aftermath of the incident at the British base at Akrotiri. Cyprus had begun quietly asking how it might secure help from its partners if things deteriorated further — if the Hezbollah-launched Shahed drone from Lebanon was followed by more.
The mutual assistance clause has existed on paper for years. It was last invoked eleven years ago, in 2015, when France triggered it following a terrorist attack — requesting support so that French troops deployed across various African countries could be relieved. In the wake of that request, a study was drawn up the following year examining the lessons of the French case. And there the matter rested.
A full decade passed before another EU member state went through the process of asking what help the Union could actually provide if it came under attack. When Cyprus began doing exactly that, it discovered something uncomfortable: in the intervening years, virtually nothing had been done to advance the discussion or translate it into concrete steps.
The reasons are not hard to find. Most EU member states are also NATO members, and they had no appetite whatsoever for opening this conversation — fearing it would irritate Washington, or leave them open to accusations of undermining Alliance cohesion.
Speaking with several people on the Cypriot side who have been involved in the discussions and the study of the issue, what I have picked up over recent days is this: Article 42.7 is not the same as NATO’s Article 5, and there is no question of it replacing Article 5 in any meaningful sense. Under NATO, you are talking about military action triggered within the framework of an alliance. Under 42.7, you are talking about a legal obligation of mutual assistance.
But what Ayia Napa brought to the surface — and what deserves more attention than it has received — is not simply the political decision to open the conversation, significant as that is. More important is the fact that one country, Cyprus, actually sat down and worked through, step by step, what invoking this clause would mean in practice.
And it found serious gaps. What precisely does a state request when it activates the clause? What do other member states actually have available? What can each country realistically offer? A source I spoke to in the past 24 hours put it plainly: “Right now, none of us has a clear picture of which countries have specific procedures in place, what those procedures are, what their capabilities actually are, or how quickly they could respond.”
Other gaps have also been identified — among them the national parliamentary or constitutional processes that govern whether a country can even agree to provide assistance when asked, and the basic question of who the right point of contact actually is if such a need arises.
It is the sum of all these unknowns that has given rise to the idea of a “playbook”: a comprehensive operational guide that answers all of these questions before a crisis hits, so that when it does, the response can happen in real time. “When you know what you’re going to ask for and who you’re going to ask,” the same source told me, “you can actually plan.”
The EU leaders have taken the political decision to open the discussion. The next important step is the actual work of putting that playbook together. The European Union needs it.
