Violations of NATO airspace: How to restore deterrence

The recent violations of Allied airspace represent an unprecedented escalation of tensions between NATO and Russia. Matus Halas writes that NATO must try to protect its airspace against unauthorised activities, but the inconsistency of approach within NATO makes deterrence harder. While different incursions must be treated differently, there needs to be consistency both over time and across member states.

Widening the ceasefire toolkit: The promise of geophysical monitoring in Ukraine and beyond

Any monitoring mission deployed to observe an end to the hostilities in Ukraine is likely to incorporate a range of remote-sensing technologies to support its verification activities. Drawing on insights from the Norwegian research institute NORSAR’s real-time monitoring of the 2022 Ukraine conflict, this policy brief by Ben D.E. Dando, Kjølv Egeland, and Sebastian Schutte, finds that scientific advances and a growing availability of relevant data have made ‘seismo-acoustic’ analysis a cost-effective means of complementing, backing up, and in some cases replacing other ceasefire monitoring technologies.

Summit survival guide: How NATO’s June 2025 Summit can preserve the Alliance’s core values and interests

NATO’s upcoming Summit in The Hague comes at a key point in the Alliance’s history; Russia’s continued aggression against Ukraine, American impatience with European underspending on defence, and European fears of American withdrawal from collective defence all represent major threats. Former NATO Assistant Secretary General for Operations, Stephen Evans, and ELN Senior Associate Fellow former UK Ambassador to NATO, Sir Adam Thomson, argue that NATO’s history demonstrates it is capable of combining strength and flexibility in times of crisis. They argue for a ‘back to basics’ approach to ease internal tensions, strengthen partnerships and move towards a state of ‘managed co-existence’ with Russia.
