Most Illegal Aliens strongly believe in Racist La Raza (The Race), M.E.Ch.A. and their written Statements that Mexicans  are Entitled to the U.S. States bought from the Spanish Colonists.  And have stated that either by Out Populating (Higher Birth Rates than U.S. Citizens) or by Paramilitary Force they will seize U.S. States to form their Racist Hispanics Only Nation of Aztlan.
The Majority of Illegal Aliens work for the Mexican Drug Cartels, many are still in Debt to the Mexican Drug Cartels.  At the U.S. the Illegal Alien Gangs as the Wholesalers of the Mexican Drug Cartels are also the Enforcers at the U.S. that make sure that the Illegal Aliens pay their Debts to the Mexican Drug Cartels, and Illegal Aliens do as Ordered. example the Illegal Aliens at the U.S. transported Iranian Oods Operatives from Southwestern U.S. to Washington D.C. to attempt to Assassinate the Saudi Arabian Envoy to the U.S..
There is an Alliance with the Mexican Drug Cartels and Muslim Nation of Iran.
