In conformance with the
Presidential directive, the U.S. began providing tactical battlefield advice to the Iraqi Army. "The prevailing view", says Alan Friedman, "was that if Washington wanted to prevent an Iranian victory, it would have to share some of its more sensitive intelligence photography with Saddam."
[3]At times, thanks to the White House's secret backing for the intelligence-sharing, U.S. intelligence officers were actually sent to Baghdad to help interpret the satellite information. As the White House took an increasingly active role in secretly helping Saddam direct his armed forces, the United States even built an expensive high-tech annex in Baghdad to provide a direct down-link receiver for the satellite intelligence and better processing of the information... p. 27
The American military commitment that had begun with intelligence-sharing expanded rapidly and surreptitiously throughout the Iran–Iraq War. A former White House official explained that "by 1987, our people were actually providing tactical military advice to the Iraqis in the battlefield, and sometimes they would find themselves over the Iranian border, alongside Iraqi troops." p. 38
Author Barry M. Lando says, by 1987,
the U.S. military was so invested in the correct outcome, that "officers from the Pentagon's Defense Intelligence Agency dispatched to Baghdad were actually planning day-by-day strategic bombing strikes for the Iraqi Air Force."
[20][7] Iraq used this data to target Iranian positions with chemical weapons, according to ambassador Galbraith.
