He arrived in Oslo in August 1935 . He was given a post as a secretary with the " International Bueau of Revolutionary Youth Organisations " ( '' " Internationalen Büro revolutionärer Jugendorganisationen " '' / IBRJ ) , a combined grouping that linked member organisations of the " Socialist Youth International " , and essentially , for many purposes , an exiled continuation of the Socialist Youth League of Germany ( '' " Sozialistischer Jugend-Verband Deutschlands " '' / SJV ) . The IBRJ operated under the auspices of what was known , at this time , as the " London Büro " . The Oslo affiliate was led by Willy Brandt , with whom Peter Blachstein was able to build a relationship of mutual trust . The two men worked closely together . One of Blachstein 's principal jobs involved producing the International Youth Bulletin ( '' " Internationalen Jugend Bulletin " " '' ) . He was also entrusted with organising and implementing a theoretical training programme for the IBRJ , designed to help create a united front against fascism . It was only several years later , after Stalin 's political purges and his own more personal experiences of Stalinist communism in action during his time in Spain , that Blachstein would become implacably opposed to any sort of political alliance with the communists
