CNN found that intervention is often weighed against political and economic costs.

Declassified U.S. government documents show that while Saddam Hussein was gassing Iraqi Kurds, the U.S. opposed punishing Iraq with a trade embargo because it was cultivating Iraq as an ally against Iran and as a market for U.S. farm exports.

According to Peter Galbraith, then an idealistic Senate staffer determined to stop Hussein from committing genocide, the Reagan administration "got carried away with their own propaganda. They began to believe that Saddam Hussein could be a reliable partner."."
