- Mark Twain's Weapons of Satire, a collection of articles, essays, and such written against American imperialism against the Phillipines and Cuba.
- Howard Zinn's People's History of the 20th Century
- Zinn's People's History of American Empire, which picks up at the close of the Indian Wars.
- Albert Marrin's The Spanish-American War, which is more apologetic than critical but still admits to the brutal treatment of the Phillipines by American forces. Interestingly, both Marrin and Bradley see McKinley as someone interested in peace, but beaten into submission by the press and warmongers like Roosevelt into sanctioning war against the Spanish.
