This chapter discusses the challenges that the war against Ukraine has brought for the EU, putting particular emphasis on the question as to what extent these are linked to a conflict between liberal democracy and autocracy. The EU and its Member States are having to reposition themselves in a changing world order that is no longer liberal, but at least multipolar. There are new political realities, not only in political and economic, but also in ideational terms. Adjusting to this new setting is difficult for manifold good reasons: China is trying to gain (geo)political and economic power and influence; several big states abstained from voting on condemnation of the Russian invasion in the UN General Assembly; and a presidential election is coming up in the USA in 2024. With regard to the EU itself, Ukraine, Georgia and Moldova want to become EU members, while the EU already faces rule-of-law issues with Poland, Hungary, Romania and Bulgaria. In all this, the war is often discussed as a conflict between an autocratic regime on the one hand and the liberal democracies of Europe and the EU, to which Ukraine wants to belong, on the other. However, liberal democracy is also under threat in the EU itself and not only from outside the EU. Authoritarian tendencies and right-wing populist parties are on the rise in several EU states; there is visible democratic deconsolidation, i.e. citizens losing trust in representative democracy, and democratic backsliding. Consequently, for the EU to defend its values and liberal democracy is a challenge not only externally, but also internally. The war only amplifies these multiple tensions.
