 Many commentators when discussing the influence of ethnic interest groups tend to focus on new entrants to the competition for influence while accepting that the historic role that the Anglo-Saxon ethnic group had is no longer influencing, the foreign policy of the United States.According to the Anglo authors as it usually is it was the United States' Anglo-Saxon's ethnic-ideological identity that, according to Paul McCartney, drove it to enter into the Spanish–American War.Similarly, United States foreign policy in the mid-20th century was shaped in favor of South African apartheid, according to Catherine Scott, as a result of the influence of people who identified with the Afrikaners based on a feeling of shared "whiteness."
