Partly as a reaction to this confiscation of a manuscript copy of his forthcoming book, he began recruiting people into the Universal Gentiles' League (aka the Universal Gentiles' Club), an organization he founded whose primary purpose was to raise awareness of and support for the issues and claims he planned to present in great detail in his forthcoming book.

He began his recruitment campaign by mailing circulars to thousands of people (mostly to Russian emigres living in the U. S.), offering details about, and membership in, the League.
