The amendment would “strike the current ban on domestic dissemination” of propaganda material produced by the State Department and the Pentagon, according to the summary of the law at the House Rules Committee’s official website.

The tweak to the bill would essentially neutralize two previous acts—the Smith-Mundt Act of 1948 and Foreign Relations Authorization Act in 1987—that had been passed to protect U.S. audiences from our own government’s misinformation campaigns.

In a little noticed press release earlier in the week — buried beneath the other high-profile issues in the $642 billion defense bill, including indefinite detention and a prohibition on gay marriage at military installations — Thornberry warned that in the Internet age, the current law “ties the hands of America’s diplomatic officials, military, and others by inhibiting our ability to effectively communicate in a credible way.”

The bill’s supporters say the informational material used overseas to influence foreign audiences is too good to not use at home, and that new techniques are needed to help fight Al-Qaeda, a borderless enemy whose own propaganda reaches Americans online.

Critics of the bill say there are ways to keep America safe without turning the massive information operations apparatus within the federal government against American citizens.

The new law would give sweeping powers to the State Department and Pentagon to push television, radio, newspaper, and social media onto the U.S. public. “It removes the protection for Americans,” says a Pentagon official who is concerned about the law. “It removes oversight from the people who want to put out this information. There are no checks and balances. No one knows if the information is accurate, partially accurate, or entirely false.”

According to this official, “senior public affairs” officers within the Department of Defense want to “get rid” of Smith-Mundt and other restrictions because it prevents information activities designed to prop up unpopular policies—like the wars in Iraq and Afghanistan.
