Brexit will profoundly change politics in the European Union, and all countries will have to adjust to the new situation. But the issue is more pressing for small member states that are more dependent on international organisations than big states.
This article studies how the institutional setting affects a small state's preparations for Brexit in the areas of the common security and defence policy and internal market. Contrary to the expectations, it shows that the Czech Republic, the small state under scrutiny, has invested more effort into a preventive adjustment in the internal market policy than to the CSDP.
This result is explained by the existence of alternative institutional frameworks that are expected to mitigate the impact of Brexit on EU's security and defence policy. It also suggests that while small states profit from the existence of strong institutions, they also face the risk of unmitigated impact when these institutions change.
