Unhumans: The Secret History of Communist Revolutions (and How to Crush Them) is a 2024 American political polemic by alt-right conspiracy theorist Jack Posobiec and co-author Joshua Lisec.

The core thesis of the tome holds that the American left intends to terrorize and subjugate the United States under a communist dictatorship, as leftists have allegedly done or attempted in many places throughout history.

[3] In it the authors laud the contributions of Francisco Franco, Chiang Kai-shek, Augusto Pinochet, Joe McCarthy, Julius Caesar, and Elon Musk to what they frame as an existential struggle against the dark forces of communism.

The book features praise from public figures, including Tucker Carlson,[a] Donald Trump Jr.,[b] Michael Flynn,[c] and Robert Stacy McCain.

The book, according to Corn, describes the January 6 United States Capitol attack as a false-flag trap sprung as a "purge of Trump supporters... from public life", and also advises that law enforcement in red areas should target antifa, Black Lives Matter, and some NGOs, as "It is time to stop playing by rules they won’t".
