Our Mission
The Center for Advanced Security, Strategic and Integration Studies (CASSIS) is an interdisciplinary research center at the Rheinische Friedrich-Wilhelms-Universität Bonn in the field of strategic foresight, European and security policy research. Committed to the approach "Global Challenges Need European Responses", CASSIS contributes in interdisciplinary and inter-institutional work to develop, evaluate and publicly discuss European strategies to current challenges in the field of foreign and security policy.
Our Partners
Since 2019, CASSIS has developed into an important platform for the transfer of academic expertise and knowledge on pressing strategic topics both to the academic and non-academic audiences through a range of our research and high-profile teaching and event formats. While doing so, we were able to receive invaluable support from our great partners. CASSIS is very grateful to their support and we are proud to be well connected to many wonderful institutions. Together with our valued and trusted partners, we are able to foster discussions on matters of strategic importance near and abroad and jointly conduct and advance important research projects.

From 19 October to 22 October 2023, ISFB will be held for the eighth time in person on the premises of the University of Excellence Bonn as the most important international security conference in North Rhine-Westphalia and all neighboring federal states.
Our Focus
The content focus of CASSIS is, on the one hand, on the interdisciplinary engagement with traditional foreign and security policy topics such as interstate conflicts, competing international order systems, and a return of geopolitics, and on the other hand, on non-traditional security challenges related to space, cyber, climate, and energy security, terrorism, and human security.

The discussion shed light on how the EU and its Member States can remain competitive while protecting their interests and values.
Current Media Contributions
“Certainly Not Normal”: Prof. Dr. Ulrich Schlie Criticizes Planned Baerbock Move to the UN
Annalena Baerbock is set to become President of the UN General Assembly, a move experts view as unusual and politically controversial. Her transfer to New York is not seen as a career advancement and has drawn criticism, particularly because the originally nominated diplomat, Helga Schmid, was sidelined. The process could also have long-term effects on Germany's diplomatic reputation.
Prof. Ulrich Schlie on TRT Global: Turning point in Berlin - Will the new government bring stability?
Germany is facing a twofold challenge: Domestically, pressure is growing due to the AfD and social polarization, while Trump's return and global uncertainties are exacerbating the course of foreign policy.
Prof. Heinemann-Grüder on n-tv: “People are being forcibly converted to Russianness”
Following the example of zoning in Germany after the Second World War, the USA is proposing a model for Ukraine. “It has the flavor of the 19th century,” says peace researcher Andreas Heinemann-Grüder. Meanwhile, Trump is trying to achieve a ceasefire. But that also seems a long way off.
Turkey at a crossroads - Prof. Dr. Ulrich Schlie on the Hessischer Rundfunk programme ‘DER TAG’
Turkey is playing an increasingly important role within NATO and is skilfully using its strategic influence and foreign policy contacts, for example with Russia and Ukraine. President Erdoğan combines economic interests with national security. Turkey is thus acting above its weight class - but this has increased significantly in recent years, argues Prof. Dr. Ulrich Schlie in the podcast ‘DER TAG’.
Prof. Heinemann-Grüder at GMX: The hurdles of Ukrainian elections: martial law, destruction and logistical problems
The Ukrainian government is under pressure to hold elections. However, the war and the associated challenges pose major hurdles. According to experts, it is difficult to hold elections under the current conditions.

Current Scientific Publications
Connectivity and ‘Reglobalization’: India-Middle East-Europe Economic Corridor and its Potential Digital Future
Dr. Gedaliah Afterman, Dr. N. Janardhan, Mohammed Baharoon & Dr. Maximilian Mayer argue that the India-Middle East-Europe Economic Corridor (IMEC) remains a strategic opportunity for driving economic growth, promoting technological collaboration, and serving as a platform for regional stabilization. The authors also stress that such initiatives have the potential to bolster middle powers and an inter- and trans-regional approach, thus mitigating U.S.-China bipolarism and fragmentation.

After NATO — the way forward
Emilian Kavalski and Maximilian Mayer write about the growing rift between Europe and the United States, drawing parallels between Winston Churchill’s contradictory views on America and the current strategic dilemmas facing Europe. While publicly advocating for a strong Anglo-American alliance, Churchill privately viewed the U.S. as an unreliable and self-interested partner—an argument that resonates today as the Trump administration actively undermines European security. In response, the authors call for Europe to pursue an independent defense strategy, moving away from reliance on the U.S. and toward a new security architecture.
Election campaign in focus: Disinformation and the Bundestag election 2025
The upcoming Bundestag election is threatened by foreign disinformation campaigns aimed at undermining trust in the democratic process. Russia, in particular, is relying on manipulated content and targeted influence on public opinion. Security authorities are responding with various measures to counter this threat.
Enhancing European Space Access: Fostering Innovation Ecosystems to Strengthen EU Space Capabilities
The relevance of the space sector will continue to increase in the future. Against the backdrop of the current geopolitical power shifts, the EU faces the challenge of developing a sustainable and robust strategy for the development of its own space capabilities. In the new CASSIS Policy Paper, Ulrich Schlie, Gregory Tutton and Philip Schäfer analyze the EU's strategic position in space and provide suggestions and impulses for improving Europe's space capabilities.
Follow-Up: Global Health in Crisis
Maximilian Schranner highlights the U.S. withdrawal from the World Health Organization (WHO) under Donald Trump, which represents less an unexpected break and more a continuation of the ongoing weakening of international health structures. In light of this development, the new federal government must acknowledge these new realities and work with international partners to establish a minimal global health protection framework.
U.S.-China Digital Fragmentation Is Putting the World in a Bind
Laura Mahrenbach and Maximilian Mayer write about the increasing digital fragmentation driven by regulation and national interests in major tech powers such as the U.S., China and the EU. To address the challenges and risks, they argue that countries should adopt a strategy of pragmatic resilience combined with cooperative approaches.
Transatlantic Cooperation in the Chip War
Philip Nock critically examines the U.S. and EU Chips Acts, which aim for a strategic realignment of semiconductor production, highlighting differences in funding, regulation and implementation approaches. The article concludes by emphasizing the urgency of strengthened transatlantic cooperation to reduce economic dependencies and ensure supply chain security in a world increasingly shaped by geopolitical challenges.
