Phalanx of defence pacts? Mapping bilateral defence partnerships in Europe

Böll EU Brief
Europe’s defence map is being redrawn. Our new Böll EU Brief tracks over 160 defence partnerships signed since 2014 among EU countries, the UK and Ukraine – most of them after Russia’s full-scale invasion of Ukraine. Bilateralism boosts trust, interoperability and procurement speed, but also risks duplication and fragmentation. To turn this patchwork into strategy, the EU and NATO should map and integrate these deals into joint planning, strengthen the European Defence Agency’s role, and use bilaterals to offset declining US support.

Budgeting for security?

Discussion paper
The ReArm Europe/Readiness 2030 proposal has limited fiscal impact and is unable to address the persistent lack of coordination among Member States, as it does not adequately incentivise joint procurement. Instead, the authors suggest to future-proof the EU's fiscal rules and develop an EU grants-mechanism tied to strategic cooperation, greater parliamentary oversight, and a broader concept of security that includes climate and democratic resilience.

Cable diplomacy: Securing influence, data and global rules

Böll EU Brief
Subsea data cables are the digital lifelines of our modern world. Yet, external factors frequently expose vulnerabilities in the network and its supporting infrastructure. While around 150 cable faults occur globally each year, states suspect a growing number of cable faults to be linked to hybrid or malicious activity. Recognising that many states around the world face similar risks, the EU Action Plan on Cable Security proposes to establish “an advanced cable diplomacy”. But cable diplomacy is not a one-size-fits-all strategy. Technological sensitivities, dual-use aspects and geopolitical considerations demand a tailored approach. Where and how should the EU build effective cable diplomacy partnerships?

Beyond Brexit: A new chapter for EU-UK relations

Böll EU Brief
The EU and the UK are holding their first post-Brexit summit on 19 May. Since coming to power in July 2024, the focus of Labour’s much-vaunted ‘reset’ with the EU has been on building friendly relations with EU institutions and Member States. Whilst these overtures have been positively received, (substantive) progress has been slow. The summit will therefore be crucial in determining whether the two sides can move from ambition to action.
