U.S. President George W. Bush has given Israel an "amber light" to begin preparations for a military attack on Iran, a Pentagon official told The Sunday Times this week. According to the official Amber means get on with your preparations, stand by for immediate attack and tell us when you're ready," the official said. The official told the Times that Bush informed the Israeli government he would back an Israeli plan to strike Iran's main nuclear sites with long-range aerial weapons if diplomatic talks over Tehran's contentious atomic program broke down. 07/13/08
