At the beginning of this week, NATO warned about an ‘unusual’ concentration of Russian forces close to the Ukraine border. So far, the Kremlin has dismissed the warning as “alarmist” while the US alerted allies about the possibility of Moscow preparing for a possible invasion of Ukraine. Mark Leonard is joined by Marie Dumoulin the new director of our Wider Europe programme, in her first week on the job, and ECFR Senior policy fellows Gustav Gressel and Kadri Liik to talk about the Russian military built up on Ukraine´s borders: how serious is the situation?
