ASAD AIR BASE, Iraq, September 03, SPA -- U.S. President George W. Bush made a surprise visit to Iraq on Monday, using the war zone as a backdrop to argue his case that the buildup of U.S. troops is helping stabilizing the nation. Bush secretly flew 11 hours to Iraq as a showdown nears with Congress over whether his decision in January to order 30,000 more U.S. troops to Iraq is working. Defense Secretary Robert Gates arrived ahead of Bush, and convened a meeting with the country's top political leaders to highlight Bush administration hopes for prodding Iraq into a «bottom-up» approach to national reconciliation. Gates conferred with senior U.S. officials, including Gen. David Petraeus and U.S. ambassador to Iraq Ryan Crocker , before opening a session with Prime Minister Nouri al-Maliki, President Jalal Talabani, and other top Iraqi officials from Baghdad. Bush and his national security team flew directly to this air base in a remote part of Anbar province, bypassing Baghdad in a symbolic expression of impatience with political paralysis in the nation's capital. The gesture underscored the U.S. belief that the spark for progress may come at the local level. Next week, Petraeus, the top U.S. commander in Iraq, and Crocker, testify before Congress. Their assessment of the conflict, along with a progress report the White House must give lawmakers by Sept. 15, will determine the next chapter of the war, the Associated Press reported.
