As part of their plans to destroy Aryan civilization, Chamberlain wrote: "Consider, with what mastery they use the law of blood to extend their power." Chamberlain wrote that Jewish women were encouraged to marry Gentiles while Jewish men were not, so the male line "remained spotless ... thousands of side-branches are cut off and employed to infect Indo-Europeans with Jewish blood." In his account of the Punic wars between "Aryan Rome" and "Semitic Carthage", Chamberlain praised the Romans for their total destruction of Carthage in 146 BC at the end of the Third Punic War as an example of how Aryans should deal with Semites.
