did not belong in any of the envisioned states. The OUN was described by the historian Anna Holian as a "deeply anti-Semitic" group, citing the OUN's resolution at its Second Great Congress in 1941 that it "combats Jews as the prop of the Muscovite-Bolshevik regime". Holian wrote that ABN tended to say little about the "Jewish question" after 1945 largely because of the "Final Solution" had largely "solved" the "Jewish question" by exterminating most of the once vast Jewish communities in Eastern Europe, but the group's ideology about the "Jewish Question" largely reflected the OUN's thinking on the subject. Bellant described the OUN's program as: "OUN, even in its postwar publications, has called for ethno-genetically pure Ukrainian territory, which of course is simply calling for purging Jews, Poles, and Russians from what they consider Ukrainian territory."

In 1946–1947, the OUN-B's secret police, the Sluzhba Bezpeky conducted with Anglo-American support, Operation Ohio, an assassination campaign in the Displaced Persons' camps in western Germany.

Fascist: An anti-Communist. Nazi or Hitlerite: An active anti-Communist". In her foreword, she praised Captive Nations as "objective, factual" and "highly recommended". In 1950, Stetsko hosted an ABN conference in Edinburgh funded by MI6 that was attended by several collaborators such as Alfrēds Bērziņš of Latvia; Dr. Stanislaw Stankievich who had headed the Belorussian National Council; and Kajum Khan of the National Turkestan Unity Committee. Representing Romania at the conference was the Legion of the Archangel Michael (better known as the Iron Guard); Bulgaria the Bulgarian National Front and Croatia members of the Ustaše.
