Washington, DC - CIA and Defense Intelligence Agency war-games have predicted unfavorable consequences of a U.S. pre-emptive strike on Iran's nuclear facilities.

Newsweek quoted an Air Force source as saying, "The war-games were unsuccessful at preventing the conflict from escalating."

Newsweek National Security Correspondent John Barry and Special Correspondent Dan Ephron have said administration officials were instead hoping to cause a regime change in Tehran-by covert means. However, the officials weren't ruling out the possibility of using force if necessary.

Sources quoted by Newsweek said circulated memos echo the administration's unsuccessful Iraq strategy: oust the existing regime and quickly install a pro-U.S. government. The plan has found disfavor with some U.S. military leaders, and there's no evidence it has any backers at the cabinet level.
