WASHINGTON, Jan 3, SPA -- U.S. President George W. Bush is expected to announce his new Iraq strategy in an address to the nation early next week, several sources in Washington told CNN Tuesday. The president has not yet signed off on any changes, including a possible increase of U.S. troops, according to sources with information about Bush's deliberations on Iraq. However, the sources say he is "driving toward a conclusion" and a plan is "taking shape" which is "getting more detailed" as the president puts "on the finer points." National Security Council spokesman Gordon Johndroe denied a report Tuesday that Bush was ready to sign off on increasing troop strength in Iraq by 20,000, saying that "the president has not made any decisions."--SPA www.spa.gov.sa/415619
