War News, the IRA's main publication, became increasingly pro-Nazi in tone, even claiming active IRA involvement in the German bombing of British cities. But more chillingly it began to ape anti-Semitic arguments. Satisfaction was expressed that the 'cleansing fire' of the German armies was driving the Jews from Europe. British war minister Hore Belisha was described as a 'wealthy Jew' only interested in 'profits'. War News condemned the arrival in Ireland of 'so-called Jewish refugees', along with unspecified numbers of 'Albanian, Abyssinian, Mongolian [and] Tartars'. These new arrivals were not only supposedly putting Irish people out of work but also exploiting those that they employed. Belfast was said to be increasingly in the 'hands of international Jewry' because of this influx. 'The Jews', War News warned, were 'like the English, when they are strong they bully and rule.' In Dublin de Valera's government was also dominated by 'Jews and Freemasons' who were becoming the 'new owners of Ireland'. Fianna Fáil TD Robert Briscoe was singled out for attack.
