Romania: A key country on NATO’s south-eastern flank
This news brief examines Romania, noting its increasingly prominent geostrategic role since the end of the Cold War, as it has gradually integrated into NATO and the EU, a process that began in the early 2000s. It then highlights the country’s central importance since Russia’s invasion of Ukraine in 2022, owing to its location on the Black Sea and its relations with Turkey. Finally, it highlights internal political instability and how this has been exploited by Russia through hybrid attacks (including drone strikes, as well as campaigns of interference and disinformation).

Hungary: Between strategic continuity and political change
As a pivotal state in Central Europe, Hungary combines close integration with Western structures with a strategic culture characterised by the pursuit of autonomy and the preservation of its sovereignty. Under Viktor Orbán, this stance has manifested itself in a policy of «multi-alignment», that is to say, varying degrees of alignment with the European Union, NATO, Russia, Turkey and China. Péter Magyar’s rise to power marks the beginning of a new political phase, but the geopolitical, energy-related and institutional constraints that shape Hungarian politics remain largely unchanged.

In this pivotal and historic year marking the Institute’s 90th anniversary, we look back at the archives that have shaped strategic thinking and the spirit of defence. From 1936 to 1977, illustrious figures — from Charles de Gaulle to John F. Kennedy, including Raymond Aron and Léopold Sédar Senghor — addressed IHEDN students to analyse their era.
