officer of the Ukrainian Galician Army) Ivan Babij. Most of these killings were organized locally and occurred without the authorization or knowledge of the OUN's emigre leaders abroad. In 1930 OUN members assaulted the head of the Shevchenko Scientific Society Kyryl Studynsky in his office. Such acts were condemned by the head of the Ukrainian Greek Catholic Church, Metropolitan Andriy Sheptytsky, who was particularly critical of the OUN's leadership in exile who inspired acts of youthful violence, writing that they were "using our children to kill their parents" and that "whoever demoralizes our youth is a criminal and an enemy of the people." OUN's terrorist methods, fascination with fascism, rejection of parliamentary democracy and acting against Poland on behalf of Germany did not find support among many other Ukrainian organizations, especially among the so-called Petlurites, i.e. former activists of the Ukrainian People's Republic. As Polish persecution of Ukrainians during the interwar period increased, many Ukrainians (particularly the youth, many of whom felt they had no future) lost faith in traditional legal approaches, in their elders, and in the western democracies who were seen as turning their backs on Ukraine. The young were much more radical, calling for the use of terror in political struggle, but both groups were united by national radicalism and advocacy of a totalitarian system. The leader of the "old" group Andriy Melnyk claimed in a letter sent to the German minister of foreign affairs Joachim von Ribbentrop on 2 May 1938 that the OUN was ideologically akin to similar movements in Europe, especially to National Socialism in Germany and Fascism in Italy. This period of disillusionment coincided with the increase in support for the OUN. By the beginning of the Second World War, the OUN was estimated to have 20,000 active members and many times that number of sympathizers. Many bright students, such as the talented young poets and Olena Teliha (executed by the Nazis at Babi Yar) were attracted to the OUN's revolutionary message. As a means to gain independence from Polish and Soviet oppression, before World War II the OUN accepted material and moral support from Nazi Germany. The Germans, needing Ukrainian assistance against the Soviet Union, were expected by the OUN to further the goal of Ukrainian independence. Although some elements of the German military were inclined to do so, they were ultimately overruled by Adolf Hitler and his political organization, whose racial
