Legal and illegal aliens. Ways in which Mexicans try to take possession of the United States under the leadership of left-wing organizations. My book is divided in three parts. The first part consists of a synthesized history of the countries of the immigrants that are concerning to the United States, their governments, their laws and their ways of life. The second part consists of what we can expect from the immigrants according to their habits of life in their home countries, the intentions and actions of the Mexican immigrants and government. The third part or the epilogue consists of the reactions of certain political figures and the U.S. government, and my premonitions.
