Hersh has written a series of articles for The New Yorker magazine detailing military and security matters surrounding the US-led invasion and subsequent occupation of Iraq. In a 2004 article, he alleged that Vice President Dick Cheney and Secretary of Defense Donald Rumsfeld circumvented the normal intelligence analysis function of the CIA in their quest to make the case for the 2003 invasion of Iraq. Another article, Lunch with the Chairman, led Richard Perle to say that Hersh was the "closest thing American journalism has to a terrorist."
