In the past few weeks, the US defence secretary, Donald Rumsfeld, ordered contingency plans for a war on Syria to be reviewed following the fall of Baghdad.

Meanwhile, his undersecretary for policy, Doug Feith, and William Luti, the head of the Pentagon's office of special plans, were asked to put together a briefing paper on the case for war against Syria, outlining its role in supplying weapons to Saddam Hussein, its links with Middle East terrorist groups and its allegedly advanced chemical weapons programme. Mr Feith and Mr Luti were both instrumental in persuading the White House to go to war in Iraq.

....However, President George Bush, who faces re-election next year with two perilous nation-building projects, in Afghanistan and Iraq, on his hands, is said to have cut off discussion among his advisers about the possibility of taking the "war on terror" to Syria.

"The talk about Syria didn't go anywhere. Basically, the White House shut down the discussion," an intelligence source in Washington told the Guardian.
