The principal Cossack émigré leader after 1945 was Nikolai Nazarenko, the self-proclaimed president of the World Federation of the Cossack National Liberation Movement of Cossackia, who enjoyed a prominence in New York as the organizer of the annual Captive Nations parade held ever July. In 1978, Nazarenko dressed in his Don Cossack uniform led the Captive Days day parade in New York city, and told a journalist: "Cossackia is a nation of 10 million people. In 1923 the Russians officially abolished Cossackia as a nation. Officially, it no longer exists...America should not spend billions supporting the Soviets with trade. We don't have to be afraid of the Russian army because half of it is made up of Captive Nations. They can never trust the rank and file". The journalist Hal McKenzie described Nazarenko as having "cut a striking figure with his white fur cap, calf-length coat with long silver-sheathed dagger and ornamental silver cartridge cases on his chest". Nazarenko was also the president of Cossack American Republican National Federation, which in turn was part of the National Republican Heritage Groups Council, and he attracted much controversy in the 1980s owing to his wartime career and certain statements he made about Jews. The American journalist Christoper Simpson in his 1988 book "Blowback: America's Recruitment of Nazis and Its Effects on the Cold War" called Nazarenko a leading Republican activist who made "explicit pro-Nazi, anti-Semitic" statements in his speeches.
