It's how they took control of Saudi Arabia (through miscegenetion, subversion, and infiltration of the Saudi royalty), through creating "Muslim" terrorist organizations, which are actually led and operated by jews, through interbreeding with black slaves in the U.S. (most slave owners were jews, and most of the half breeds were jewish admixture), and how they infiltrated European societies, by mixing with locals and using the "fellow White people" mantra. This is why there's such a wide variety of jews throughout the world, when in reality a race of people is supposed to be homogeneous. If you go back to Biblical times, they were ardent race mixers then, too, often in direct violation of what God commanded them to do.
