Abstract:
The challenges of climate change for the military and the security aspects of space are the latest critical issues explored as part of a joint programme between the IISS and the Hanns Seidel Foundation. On 23 and 24 June 2021 the Hanns Seidel Foundation and the IISS held the fourth meeting of the High-Level Study Group on the Future Defence of Europe. While earlier sessions of the study group had focused on threat perceptions, military capabilities, the implications of intensifying great-power competition, and the impact of the COVID-19 pandemic on European defence, the growing impact of climate change on defence and security was the focus of the first day’s discussion. The second day considered developments in space exploitation, and the challenges and opportunities this raises for defence and security. The following paper draws on these discussions and includes the key themes and topics that were raised.

Abstract:
Two decades ago, the notion of arming an uninhabited aerial vehicle (UAV) was little more than a niche pursuit. Today, at least 20 countries have weaponised UAV systems in their inventories, with other nations pursuing acquisition, while the capability is also proliferating to non-state actors. The air vehicles range from small, crude, hobbyist-style UAVs favoured by some non-state groups, to large, long-endurance platforms capable of being fitted with a range of sensors and air-to-surface weapons. Technological development continues apace with an increasing emphasis on greater automation and reducing the human workload, along with the emergence of a type of hybrid UAV and air-to-surface munition along side the more established loitering munition. While uninhabited systems are increasingly embraced by many armed forces, they remain an uneasy subject in the wider public realm, where the perceived lack of human control remains an ethical issue. There also continues to be concern in the legal community regarding how increasingly automated – and perhaps one day autonomous – weapon systems fit within the law of armed conflict – legal concept rather than legislation, sometimes also referred to as international humanitarian law. These subjects were the focus of a 21–22 June 2021 seminar organised by IISS Europe to help further the debate and to better understand the implications of weapons-capable uninhabited systems. This paper reflects the discussions and many of the issues raised by the participants.

Abstract:
In 2019, European governments’ combined defence spending, when measured in constant 2015 US dollar terms, surpassed the level reached in 2009, before the financial and economic crisis led to a series of significant defence-spending cuts. However, a different strategic paradigm – one that Europe is struggling to adjust to and which is once more a concern for European governments – has re-appeared in this past decade: great-power competition. Russia attempted to change international borders in Europe through the use of force in 2014 by annexing Crimea and continues to support an armed insurgency in eastern Ukraine. Moscow’s challenge to Euro-Atlantic security exists in multiple dimensions: as both a conventional military and also a hybrid-warfare issue, with Russia working to dislocate existing societal alignments and disrupt political processes in Western states. The poisoning of a former Russian intelligence officer (and of his daughter) in the United Kingdom, attributed by the British government to Russia, underlines further how much the character of conflict has changed. How to manage the challenge Russia poses without simply reverting to Cold War logic remains a worrying problem for governments in NATO and the European Union member states. Meanwhile, European security establishments are beginning to recognise the growing political, economic and military influence of a rising China. Although less of an immediate challenge, China’s growth in these areas has possible profound consequences in the long run. Indeed, in December 2019, NATO declared: ‘We recognise that China’s growing influence and international policies present both opportunities and challenges that we need to address together as an Alliance.’2 For the United States, China has already become the pacing military threat. The US Indo-Pacific Strategy Report, released in June 2019, opens with the assertion that ‘the Indo-Pacific is the Department of Defense’s priority theater’. In other words, the European theatre is not. European analysts and officials have begun to wonder whether the US might begin to see Europe through an Asian lens, seeking to generate European commitments to the Indo-Pacific region, or at the very least getting Europeans to take on greater responsibility for their own security and thereby freeing up US resources. Although there will be some elements of the US military presence in Europe that are indispensable to US military action in other regions of the world, that might not be enough to sustain Washington’s firm commitment to European security in the future, regardless of who occupies the White House. Significantly, not even the US has the capability to fight two major wars simultaneously any more, meaning binary choices regarding focus are inevitable. As some observers have argued, Europeans need to urgently assess what Washington’s choices in this regard – and their implications for Europe – might look like. Considering both how to deter Russia and what a European contribution to containing China might entail represents a major challenge for Western European nations, which have relegated defence to a secondary position, as almost a discretionary activity. European states partially demobilised in the 1990s and early 2000s, intellectually and in terms of their force structures, in response to the end of the Cold War. For example, according to IISS data, in 1990 West Germany alone was thought to be able to field 215 combat battalions and the UK 94. Today it is a fraction of that. However, security challenges relating to regional instability, crisis management and transnational terrorism – which all dominated the previous two decades – have not disappeared. On the contrary, all these still demand attention and the investment of European resources. While there is a growing recognition among Europe’s analytical community, and some governments, that things cannot simply continue as before in terms of regional security and defence, coherence and resolve among core actors in the Euro-Atlantic sphere have weakened. The US administration has intensified its call for better transatlantic burden sharing, at the same time displaying a cavalier attitude to the collective-defence commitment enshrined in NATO. France’s President Emmanuel Macron has also expressed severe doubts about the viability of NATO’s collective-defence mission. In addition, the British decision to leave the European Union in 2020 implies that the EU has lost one of its most militarily experienced and one of its most capable member states. There is a tendency among many observers and some politicians to argue that European NATO and EU member states need to clarify the political dimension of their defence ambition, via-à-vis greater strategic autonomy, before resolving the problem of how to meet this ambition militarily, at what cost and in what time frame. Indeed, at times, the debate about European strategic autonomy seems to focus more on the degree of independence from the US that its various proponents would like to achieve and less on the military requirement that autonomy is meant to respond to. It is now widely accepted across Europe that Europeans need ‘to do more’ for their own security and defence. Most of the intellectual energy allocated to this aspiration is spent on achieving better coordination – and even a level of integration – among European armed forces. This is useful, but only if it is directed at building capability to provide for the defence of Europe. The existing military capabilities of the European NATO member states fall short when compared to the force requirements generated by the political–military level of ambition as defined by NATO, or for that matter the EU.5 However, this should not be an excuse to lower the level of ambition, nor should the assumption that Europeans are unable to defend themselves be declared an inevitability. Defence output is the result of political, financial and military choices by governments. To think systematically about the challenge of providing capabilities that can meet Europe’s emerging military requirements, The International Institute for Strategic Studies and the Hanns Seidel Foundation convened a group of thinkers and practitioners from Germany and the UK. The group took seriously the US assertion that Europe needs to be able to provide for its own defence. If Europeans can achieve this, they will be valuable partners to the US in upholding and strengthening the liberal international order on which Euro-Atlantic prosperity and security depend. Meeting twice in 2019, the group discussed threat assessments, debated European capability gaps and scoped potential approaches to addressing them. The following pages draw on the group’s deliberations but do not represent a consensus position.

Abstract:
The study applies scenario analysis – with scenarios set in the early 2020s – to generate force requirements, and assesses the ability of NATO’s European member states to meet these requirements based on data from the IISS Military Balance Plus online database. The cost of closing the identified capability shortfalls through equipment acquisition has been estimated. The objective of the study is to enable informed policy dialogue both in Europe and in a transatlantic setting. The study explicitly does not intend to predict future conflicts nor the intentions of any of the actors involved. Neither does it wish to prescribe a certain path of action to be pursued by European NATO governments. The first scenario examined deals with the protection of the global sea lines of communication (SLOCs). In this scenario, the United States has withdrawn from NATO and has also abandoned its role of providing global maritime presence and protection, not just for its own national interest but also as an international public good. It thus falls to European countries to achieve and sustain a stable maritime-security environment in European waters and beyond, to enable the free flow of international maritime trade, and to protect global maritime infrastructure. The IISS assesses that European NATO members would have to invest between US$94 billion and US$110bn to fill the capability gaps generated by this scenario. The second scenario deals with the defence of European NATO territory against a state-level military attack. In this scenario, tensions between Russia and NATO members Lithuania and Poland escalate into war after the US has left NATO. This war results in the Russian occupation of Lithuania and some Polish territory seized by Russia. Invoking Article V, the European members of NATO direct the Supreme Allied Commander Europe (SACEUR) to plan Operation Eastern Shield to reassure Estonia, Latvia and Poland, and other front-line NATO member states, by deterring further Russian aggression. European NATO also prepares and assembles forces for Operation Eastern Storm, a military operation to restore Polish and Lithuanian government control over their territories.

Abstract:
In September 2015, the Russian military, predominantly though not exclusively through the use of air power, intervened in Syria’s civil war. Moscow’s aim appears to have been to bolster the Bashar al-Assad regime with even a comparatively modest Russian force, to allow it to prevail against the disparate array for opposition forces reined against the Baath administration. As 2017 drew to a close this appeared to be paying off, with the Syrian regime in an increasingly strong position, and the Russian political and military leadership effectively proclaiming success and the end of substantive hostilities. Russia’s credibility as an ally has been enhanced in the region and beyond.

Abstract:
The United Kingdom should seek to continue to support defence-technology cooperation with the European Union and partner states across all military domains. Avoiding, or at least minimising, the second-order effects of Brexit on wider defence cooperation with European partners will be easier if the UK is directly involved in the EU’s defence-technology initiatives. Specific opportunities present themselves across the military domains: Pursue cooperation in the air domain with regard to future combat- aircraft technology. While collaboration at the platform level is unlikely in the near term, exploring common R&D in key systems, such as radar, propulsion, avionics, sensors and weapons, is achievable. In the land domain, explore partnership with France and Germany on participating in the development of a next-generation main battle tank. Collaboration on applicable technologies at the component and sub- system levels should also be encouraged. This could include armour and armament R&D, and laser weapons. In the maritime domain, support cooperation in the air-defence arena, including the use of laser weapons for ship self-defence, and the use of naval vessels for ballistic-missile defence. In the space domain, examine potential cooperation on next-generation communication satellite requirements, and wider collaboration on geospatial intelligence.

Abstract:
he ability of the European Union to act in defence, today and in the future, is an important reference point in the debate about EU strategic autonomy in the context of Brexit. The EU has set itself a military level of ambition. Under the heading of the Common Security and Defence Policy (CSDP), EU member states want to be able to conduct a range of military operations. Together with the German Council on Foreign Relations (DGAP), this study assesses to what extent the EU is able to fulfil this level of ambition, today and with an outlook towards 2030. The IISS and DGAP have developed policy-compliant scenarios to assess where possible capability shortfalls lie. Our findings benchmark existing and future EU member state capabilities against the force requirements the EU level of ambition generates.
