The practice of big business promoting war to profit materially was firmly in place by the time Major General Smedley D. Butler wrote about it in his anti-corporate pamphlets. This historical biography explores the life of Butler, a little-known American Marine who exposed an alleged fascist coup to remove President Franklin D. Roosevelt from office. This text is an exploration of the political issues of the first half of the twentieth century and an examination of a complicated, valiant man who shifted from Republican ideals to anti-corporate, left-wing populism.
