Senior US figures discuss drawing down troops

President Jimmy Carter rejects a pre-emptive withdrawal of US troops but urges the Bush administration to drawdown its forces in Iraq. The US ambassador to Iraq compares the toppling of Saddam Hussein to opening a Pandoras Box. It might be argued that, as Zalmay Khalized makes so few public statements, and even fewer as frank as this one, there is a significant debate at the highest level of American government regarding the timing of any troop withdrawal.
