Did U.S. change Iraq policy to begin airstrikes months before war

The discovery, made by investigative blogger Ron Brynaert, raises questions of whether Britain and the United States violated a UN resolution to provide for the security of Iraqi citizenry in the wake of the 1991 Gulf War.
...Other U.S. commanders have admitted to “spikes of activity,” a phrase employed by both British and American officials when discussing bombings before the push for Congressional or UN approval.
“I directed it,” Defense Secretary Donald Rumsfeld told reporters at a Sept. 16, 2002 Pentagon press briefing in response to questions about the rising tide of Iraq airstrikes in 2002. "I don't like the idea of our planes being shot at. We're there implementing U.N. resolutions... And the idea that our planes go out and get shot at with impunity bothers me."
After repeated questioning about when the change was made, Rumsfeld was hesitant, and according to the transcript, reporters laughed.
"Less than a year -- less than a year and more than a week," the transcript records, “(Laughter.) I think less than six months and more than a month."
In his autobiography, American Soldier, retired U.S. General Tommy Franks, who led the 2003 invasion of Iraq, invoked the “ spikes” phrase—as far back as 2001.
"I'm thinking in terms of spikes, Mr. Secretary,” he wrote, referencing a conversation with Defense Secretary Donald Rumsfeld in December 2001, “spurts of activity followed by periods of inactivity. We want the Iraqis to become accustomed to military expansion, and then apparent contraction."
