Any normalisation of relations with Russia will only take place once Moscow gives up its imperial ambitions and pays for its crimes. There should be no notion of a new policy towards the Kremlin without change at the top and the complete removal of its threat to European security. We cannot repeat the mistakes of 1991.

Germany’s post-reunification Ostpolitik has ended in a national and European disaster. A policy that was supposed to foster peace, stability and reconciliation has resulted in war and an energy crisis. This is not to say that Germany is to blame for the aggression against Ukraine. The responsibility clearly lies with the criminal policies of Vladimir Putin and his regime. Nevertheless, Berlin needs to accept that post-reunification Ostpolitik, especially in the last 15 years, helped to enable the Kremlin to pursue its attacks on neighbours.
