The world must still be on guard against attempts to return to Nazism and theories of racial superiority, Russia's president Vladimir Putin has warned. During the celebration of the 60th anniversary of the Soviet victory over Nazi Germany in May 1945, special attention should be paid to attempts to rehabilitate Nazism, he said according to a report by the news agency "Interfax". This was "especially important, because attempts to rehabilitate Nazis and rewrite history still occur", Putin added. He was addressing the committee in charge of organizing the May anniversary celebration, to be attended, among others, by the political leaders of France, Germany and the United States. "The ideas of racial and religious superiority, behind which the claims for world leadership are hiding, serve as a ground for new threats," such as international terrorism, separatism and extremism, Putin said.
