The porosity of borders has become a key characteristic of contemporary international relations. While this has long been recognized for trade and information networks, it also has an impact on the field of defense and security.
The impossibility of clearly separating internal from external threats is not a new phenomenon, as demonstrated by the many attacks of international origin that hit the Paris area during the 1970s and 1980s.
Although the concept of a defense and security continuum has reached a consensus since the publication of the 2008 Defense White Paper in France, there is still a need to anticipate future internal-external interactions and understand their implications for the French population’s collective security. The objective of the Homeland Security program is to study more specifically:
- The process of radicalization (the role of social networks as tools of ideological radicalization and informal mobilization, the emergence of new forms of violent opposition, the repercussions of the Israeli-Palestinian conflict in France)
- Terrorism (the evolution of the international jihadist movement, the potential physical and cyber threats on critical infrastructure, the improvement of prevention and repression procedures)
- Technological and sanitary risks (early warning procedures, pandemics)
