Condemnation of Nazism is absolutely mandatory and apology is the best approach in that case, Bulgaria’s President Rumen Radev told journalists on Saturday on occasion of the recent scandal related to the Nazi salutes published by some representatives of the United Patriots in the social media. Although Europe was divided by the Iron Curtain after the war, all countries united around the stand that Nazism should be condemned. We must continue to be united around this consensus, President Radev further said. President Radev attended on Saturday the 34^th Congress of the Union of Community Centers.
