The European Union’s Strategic Test in Ukraine

Abstract

Russia’s ongoing invasion of Ukraine is the most severe challenge that the European Union faces. The EU has generally responded in a united and robust manner, overcoming the clash of national interests that had previously characterized its policymaking vis-à-vis Russia. The most transformative and significant decision that the EU has made is to treat Ukraine as a candidate for EU membership. However, cracks have appeared in the EU’s unity, and the enlargement process will be long and difficult—and it could be derailed if Ukraine’s territorial integrity is not restored. That will depend on increased European efforts and continued US military assistance to Ukraine, neither of which appear certain.
