In 2002, Beers worked for the U.S. State Department to produce propaganda videos intending to sell a “new” America to Muslims around the world by showing that American Muslims were living happily and freely in post-9/11 America. The $15 million Shared Values Initiative produced five mini-documentaries for television, radio, and print with shared values messages for key Muslim countries. Less than a month after the release of the Shared Values Initiative, the State Department abruptly discontinued it.
