Since the invasion of Ukraine, European states have taken major steps to rebuild their defense industrial bases, both to supply Ukraine and to rebuild their own militaries. Europe has been spending heavily on defense since 2022, but the Trump administration’s demand for European NATO members to take responsibility for the conventional defense of the continent has spurred further investments. Add in the Trump administration’s bellicose rhetoric around Greenland and public doubts about the reliability of America in NATO, plus the dual challenges of a resurgent Russia and a wavering United States, and the push for European officials to integrate their defenses further only grows. As European states continue to rearm in 2026, they face the prospect of rebuilding their militaries, supporting Ukraine, and deterring Russia with less U.S. support.
The new year has already shown a propensity for the unexpected. To help take stock of the way ahead for European security in 2026, we are excited to welcome Sophia Besch and Christian Mölling to this episode of Brussels Sprouts.
Sophia Besch is a senior fellow with the Europe Program at the Carnegie Endowment for International Peace.
Christian Mölling is the director of European Defense in a New Age, a Berlin-based think tank, and is a senior advisor at the European Policy Centre.
