In 1993, he was fired from the National Review by his one-time mentor William F. Buckley after Buckley called Sobran's writing "contextually antisemitic". He criticized some aspects of Jewish influence and the Israel lobby.
Sobran had some associations with the Institute for Historical Review and David Irving. He stated that "I am not, heaven forbid, a "Holocaust denier." I lack the scholarly competence to be one. [...] Why on earth is it 'anti-Jewish' to conclude from the evidence that the standard numbers of Jews murdered are inaccurate, or that the Hitler regime, bad as it was in many ways, was not, in fact, intent on racial extermination? Surely these are controversial conclusions; but if so, let the controversy rage."
