Interview: Why a Ukraine ceasefire wouldn't guarantee peace for Europe

Wolfgang Ischinger, Chairman of the Munich Security Conference, has warned that the end of the war in Ukraine would only be the start of European efforts to secure peace in Europe. Speaking to DW's Nina Haase, Ischinger also cautioned that the Trump administration's view of Europe - including what is set out in its new National Security Strategy - poses an 'ideological challenge' to Europe.
