American Empire: A post for the 4th of July

I've written already about Independence Day, in "The Fourth of July: A Marxist-Leninist look at the Revolution of 1776", which looks at some of what U.S. Marxist-Leninists William Z. Foster and Harry Haywood had to say about the bourgeois-democratic revolution in the United States. But since today's the day, I wanted to cap that off with this video, "A People's History of American Empire by Howard Zinn"
