Von der Leyen Proposes a European Article 4, a European Security Council and a Strategic Enablers Instrument
Strasbourg, 16 September 2026
Key points
- In the State of the Union address on 16 September Ursula von der Leyen proposed "Europe's own Article 4 – or an Emergency Security Protocol": "When triggered by one Member State, all Member States would convene. To coordinate a European response. To deter further escalation. And to mitigate the impact"
- She framed it as "a mechanism to flank NATO's 'Article 4'" for incidents "which fall below armed aggression but clearly threaten our national security", cited the past week in Denmark, Lithuania and Poland, and called the attempted drone attack in Leipzig "an attack using military-grade material, carried out by Russian operatives on European soil"
- She announced a new European security strategy with the High Representative, said the Commission "will set out our ideas to make a European Security Council a reality" with partners like Canada, Norway, Ukraine and the United Kingdom, and announced a European Instrument for Strategic Enablers, "fully aligned with NATO", spanning air and missile defence, strategic transport, air-to-air refuelling, space and cyber
- On Ukraine she named the Freya project as the heart of an affordable, modular missile-defence system and a programme for joint projects with Ukrainian companies "using the remaining funds from SAFE"; none of the proposals carries a figure, a legal base or a date
Ursula von der Leyen used the 2026 State of the Union to propose an EU consultation clause for attacks below the threshold of armed aggression, a leaders' security council that reaches beyond the Union, and a financing instrument for the enablers Europe borrows from the United States. The speech dates none of them.
The protocol appears as an example under the security strategy she will propose with Kaja Kallas, inside a passage arguing that "hybrid threats facing Europe are less and less hybrid and less and less threats" and that Europe "needs its own counter-hybrid playbook". As described, it obliges member states to meet. It names no output, no threshold and no relation to the treaty's existing mutual-assistance clause, Article 42.7, which the speech does not mention.
That omission has a history. The Nicosia summit in April tasked the Commission and Kallas's service with an operational blueprint for 42.7, hybrid cases included, with no delivery date; none has been published. On 7 September Kallas withdrew her High-Level Group on Defence the day before its launch, after Paris and Berlin withheld support. The new protocol lands on the same desk.
A second consultation clause does not address why the first goes unused: NATO's Article 4 has no threshold either, and Signal No. 147 records that no ally has invoked it after any flank incident since late July, last week's shootdown over Lithuania included. Capitals that decline to call a meeting they are entitled to call will not be moved by a second venue. The enablers instrument is the consequential item, because it maps onto a gap with numbers on it: the June Force Model cuts removed all eight US tankers from the pool, and air-to-air refuelling is on her list. An instrument needs a legal base and a budget line in the next financial framework; a protocol needs only a speech. Which of the two appears first in a Commission proposal will show what Wednesday was for.
