Abstract:
The United States under President Donald Trump has adopted an ambiguous position on European security. Although no immediate risk of abandonment is apparent, European countries are rethinking their defence strategies in case the US declines to support them, or provides only partial support, in a crisis. This discussion is particularly sensitive in relation to nuclear weapons, the ultimate deterrent, for which European countries depend extensively on the United States. We argue that a possible future US withdrawal from European nuclear security will force European countries to face a policy trilemma. If they stick to the existing policy framework of no proliferation and no joint deterrence, they expose themselves to nuclear blackmail, should the US withdraw its external guarantee. If they want to protect themselves from nuclear blackmail, they must choose how to provide nuclear security: either collective nuclear security, which would compromise some national sovereignty, or independent provision by individual countries, leading to nuclear proliferation in Europe. Having established that uncontrolled proliferation is an inferior outcome to some form of joint deterrence, we identify four main alternatives: an extension of the Franco-British nuclear deterrent; an extension complemented by a jointly financed expansion of existing deterrence; the absorption of the French (and perhaps British) nuclear arsenals into a European arsenal; and the construction of a separate European submarine deterrent (with Europe using French or British technology or developing new technology). We also discuss briefly forms of non-nuclear deterrence, which however would likely be a complementary rather than a substitute for a nuclear deterrent. We compare these options using a set of parameters: strategic autonomy and credibility, changes to treaties (including non-proliferation), costs, capabilities and readiness. Our analysis shows that all options have advantages and disadvantages, but some are politically, financially and militarily more feasible.

12. Not yet Trump-proof: an evaluation of the European Commission’s emerging policy platform

Policy Brief

Abstract:
The economic strategy being defined by the 2024-2029 European Commission seems to follow the prescriptions on innovation and single market reform, and the expansive approach to industrial policy, set out by Mario Draghi in his September 2024 report on European Union competitiveness, with two important differences. First, the Commission stops short of calling for World Trade Organisation-prohibited subsidies – this is welcome. Second, the Commission proposes a new state aid framework for national industrial policy rather than expansion of EU-level public investment funding. This runs the risk of weakening the single market and harming competition, with the unintended consequence of protecting incumbents and inhibiting structural change. In terms of specific policies, on defence, the Commission is right to face up to the challenge of defining an EU procurement mechanism that offers sufficient speed and cost advantages to justify large-scale funding. On economic security and international partnerships, the Commission is right to take a broader approach than a foreign economic policy focused only on supply chains. What is lacking is a much greater commitment to providing support for climate mitigation in developing countries. The second Trump presidency creates risks for the Commission strategy. President Trump has gone further than expected in threatening territorial expansion and with the speed, aggression and disregard for the rule of law with which he has started to implement his policies. These factors will complicate the EU-United States relationship. The best defence against both Trump and the competitive and security threats posed by China is to accelerate policies that address the EU’s structural weaknesses: raising productivity growth, defence capacity and economic security. Economic security, in turn, requires more resilient trade relationships, less financial dependence on the US and an improved standing with emerging market and developing economies. The EU should also seize the opportunity offered by the shift in US policy from subsidies to deregulation. While the EU should not race Trump to the bottom on environmental or financial deregulation, it should rapidly improve its own regulatory framework while building on its core strengths: human capital and the rule of law. Unlike tariff wars or discriminatory subsidies, a competition to provide a good business environment is not a zero-sum game.

13. Ukraine: European democracy’s affordable arsenal

Policy Brief

Abstract:
European NATO members must raise defence spending by enough to deter through strength an irredentist Russia. This must be done possibly without the United States and when ageing populations demand higher social spending. Raising defence spending to sufficient levels could result in a doubling of current primary deficits to just over 3 percent of GDP on average. This seems likely to be a fiscally unattainable goal for this group of countries. European NATO members, in addition to their quantitative defence spending challenge, face the qualitative challenge of significantly increasing their outlays on new modern military equipment, especially drones, to credibly deter Russia. This will require all European NATO members to significantly increase investments in their domestic and regional military-industrial capacities. While its armed forces are physically defending their country against Russia’s onslaught, Ukraine is transforming gradually into a very large, advanced and cost-competitive military equipment and weapons producer. Through the so-called ‘Danish Model’, individual European Union and NATO members are already actively funding Ukrainian defence production, helping it to help itself against Russia. Much more focus should be put on Ukraine’s ability, if fully integrated with the military-industrial sector in the rest of Europe, to produce much of the modern military equipment wanted by itself and the rest of Europe. This Policy Brief shows how Ukraine already produces drones and modern howitzers, arguably the two most important weapons in defensive warfare today, at prices well below those achieved by other Western military suppliers. The EU, with a fully integrated and funded Ukrainian military-industrial sector, will have the capacity to produce much of the cost-competitive military equipment it will need in future, while continuing to fund its welfare systems. To facilitate this development, the EU must in all defence and military-related matters begin treating Ukraine immediately as a full EU member.

14. The governance and funding of European rearmament

Policy Brief

Abstract:
Europe faces a grave security threat. Gaps in European military equipment are substantial compared to Russia’s military build-up. The European defence market is fragmented and weakened by home bias in procurement, low order numbers and technological gaps. These problems reflect the combination of past reliance on the United States and Europe’s nationally-based defence governance. With the US now retreating from its role of European guardian, greater cooperation is essential to close technological gaps and reduce rearmament costs. Unless procurement is pooled and fragmentation reduced, additional demand for defence goods will mainly drive up prices. Better-integrated defence markets would both increase competition and facilitate entry of new defence technology firms. The combination of integrated markets and scaled-up procurement could lead to a halving of unit costs. European Union measures including the European Defence Fund, the Act in Support of Ammunition Production, the European Defence Industry Reinforcement through Common Procurement Act and ReArm Europe represent progress towards strengthening the supply of military goods but the incentives offered are too small to address the home bias in procurement or to coordinate the provision of ‘strategic enablers’ such as military satellites. To go further, the EU and its European allies have two options. First, the role of the European Defence Agency could be broadened, possibly in combination with a new lending instrument similar to the EU’s 2020-22 SURE programme. Second, a European Defence Mechanism (EDM) could be created: an institution similar to the European Stability Mechanism, based on an intergovernmental treaty. The EDM would undertake joint procurement and plan for the provision of strategic enablers in specified areas, with a capacity to fund these roles. It could own strategic enablers and charge usage fees to EDM members, reducing the budgetary impact of rearmament. EDM membership would entail prohibition of both state aid and procurement preferences that benefit national defence contractors at the expense of contractors from other EDM members. Of the two options, the second is preferable, as it would (1) create a defence industry single market among EDM members, (2) create a financing vehicle that might make large-scale projects fiscally feasible, and (3) include non-EU democracies such as the United Kingdom on an equal footing, while also giving an opt-out to EU countries that lack the political appetite for more defence integration, or that have national constitutional constraints.

16. Denmark needs to rethink its multilateral engagement

Content Type:
Policy Brief
Institution:
Danish Institute for International Studies (DIIS)
Abstract:
Uncertainty about NATO’s future and American commitment to European security is challenging the foundations of Danish foreign and security policy. Denmark must face this new reality and strengthen its commitment to multilateralism as central to its long-term security and influence. Denmark’s 2023 foreign policy strategy acknowledges that ‘the rule-based world order and multilateralism are under pressure’ – a stark reality for a small state whose security and prosperity fundamentally depend on international rules. Intensified geopolitical competition, rival visions of global governance, and the erosion of consensus on international security norms have plunged multilateralism into a full-blown crisis, placing Denmark – like many countries – in an increasingly difficult position.

17. A battle against time – and against Putin’s Russia

Centre for European Policy Studies (CEPS)
Abstract:
With Putin’s war against Ukraine about to enter its third year, the EU’s enlargement policy remains at the top of its foreign policy priorities, with the focus being on both Ukraine and Moldova. This is following the European Council’s decision to open accession negotiations with both countries. But where does this leave the countries of the Western Balkans and their very long journey towards the EU which began over 20 years ago? Will these countries’ hopes for much needed political momentum in their accession prospects be fulfilled during 2024, despite the repeated delays and the EU’s failure to respect its commitments to the region over the past few years? With elections taking place across Europe offering fertile ground for Russia to deploy its arsenal of disinformation tactics, time is not on the EU’s side. To counter Russian attempts to influence developments in the region, as well as to reverse the dangerous trend of backsliding in democratic and rule of law reforms, the EU will need to adopt a more robust, consistent and determined approach towards the Western Balkans. Without any further delay, it needs to set out a much needed geopolitical and security direction for its enlargement policies in the Western Balkans.

Abstract:
“Understanding EU-NATO Cooperation: How Member States Matter” by Nele Marianne Ewers-Peters conducts a distinctly member-state based theoretical examination of interorganizational cooperation between the EU and NATO. Ewers-Peters mainly intends to demonstrate member states’ foreign/security policy orientations, roles and positions affecting the functionality and dys-functionality of Euro-Atlantic security, between the period of the end of the Cold War and 2021. The book is composed of seven chapters including conclusion and implications. By providing 28 face-to-face semi-structured interviews carried out in Berlin and Brussels between February 2017 and February 2018, with different member states’ representatives (see Appendix A.), as well as document analysis of primary and secondary sources, the book relies on well-designed qualitative research.

19. Vernacular Border Security: Citizens’ Narratives of Europe’s ‘Migration Crisis’

Abstract:
After the waters of the Mediterranean Sea washed the dead body of Alan Kurdi ashore in 2015, issues of migration, border security, and European Union (EU) migration policy gained more widespread interest. Although many scholars deal with the issue from different angles by focusing on the roles of different ‘agents’ and their roles in the politics of the EU’s 2015 ‘migration crisis’, Vernacular Border Security: Citizens’ Narratives of Europe’s ‘Migration Crisis’ argues that there is no comprehensive study analyzing the EU citizens itself (p. 4). Problematizing the passive recipient role given to the EU citizens, Nick Vaughan-Williams critically intervenes, problematizing contemporary scholarship’s “propensity to speak for, rather than to (or, perhaps better, with) ‘ordinary people’…”.1 Asking “[w]hy is it that the intensification of EU border security appears to have heightened rather than diminished border anxieties among EU citizens?” (p. 3), Vaughan- Williams highlights a theoretical and methodological shift in studying border security, one that juxtaposes ‘top-down’ elite narratives of border security with ‘bottom-up’ investigations of ordinary EU citizens’ knowledge on the issue. Chapter 1 justifies this unique theoretical shift, namely the ‘vernacular turn’ in critical security studies. Connecting elite and vernacular narratives becomes a must if we are to transcend dominant securitizing narratives of migration and see alternative ways of ‘living with’ strangers (p. 3-4). Forming such a connection allows us to understand better the interconnected relationship between the macro-level of national border security and border anxieties at the micro-level of citizens. And, in the final analysis, it is important to see how these elite narratives are both reproduced and contested locally in citizens’ everyday lives. Chapter 1 also contributes to vernacular security studies by conceptualizing ‘vernacular narratives’, which has been absent so far in the theoretical discussion (p.12).

20. The Defence of Europe by Europeans: a myth, a necessity, an ambition, a hope?

Abstract:
Without overstating the case, 2024 is shaping up to be a pivotal year. It has already been marked not only by the continuation of ongoing conflicts and crises, but also by their geostrategic effects and consequences, the full extent of which has yet to be assessed. 2024 will also be a year of great memorable moments and electoral events, a year of risks and, let's hope, opportunities, particularly for Europe. Like a leitmotif, or for some an “old chestnut”, European defence will be the focus of analysis, but also of a real stress test. With this in mind, it cannot be too early to raise a question that is vital to the future of Europe, and the European Union in particular.
