United in Hate: The Left's Romance with Tyranny and Terror is a 2009 book by Jamie Glazov.

In the book, Glazov analyses what he sees as segments of the political left's sympathies for radical Islamists.

Among those Glazov accuses of having found common ground with Islamic terrorists are Jimmy Carter, Michael Moore, Noam Chomsky, Ramsey Clark, Lynne Stewart, and Stanley Cohen, while noting that Norman Mailer called the 9/11 hijackers "brilliant", and Ted Turner calling them "brave".

"[2] Jonathan Schanzer wrote in Middle East Quarterly that Glazov "exposes the hypocrisy of leftists and liberals who claim to champion the principles of freedom, democracy, liberalism, and feminism yet support both communist and Islamist dictatorships, which implement none of these principles.

"[2] Bruce S. Thornton said in City Journal that the book "is a valuable aid for those wishing to understand one of the strangest spectacles in history: a large number of a society’s most privileged people, who enjoy unprecedented freedom, education, material well-being, and leisure, relentlessly attacking the institutions and ideals that make such benefits possible—and extolling enemies who seek to destroy all of these goods.
