WHILE campaigning in public for a speedy withdrawal of US troops from Iraq, Sen. Barack Obama has tried in private to persuade Iraqi leaders to delay an agreement on a draw-down of the American military presence.

According to Iraqi Foreign Minister Hoshyar Zebari, Obama made his demand for delay a key theme of his discussions with Iraqi leaders in Baghdad in July.

While in Iraq, Obama also tried to persuade the US commanders, including Gen. David Petraeus, to suggest a "realistic withdrawal date." They declined.

Obama has made many contradictory statements with regard to Iraq. His latest position is that US combat troops should be out by 2010. Yet his effort to delay an agreement would make that withdrawal deadline impossible to meet.
