The United States may have to alert thousands more National Guard and Reserve troops within weeks that they are needed for duty in Iraq, the Pentagon's second-ranking general said Wednesday. The Bush administration still hopes that Turkey, India, Pakistan or South Korea will contribute thousands of troops for security duty in Iraq, said Marine Corps Gen. Peter Pace, vice chairman of the Joint Chiefs of Staff. But military planners are not counting on it. Although reservists are called upon to serve in every overseas conflict, the scope of their involvement and length of their duty in Iraq have raised politically sensitive questions about whether the Bush administration is asking citizen soldiers to shoulder too much of the burden. The United States has about 130,000 troops in Iraq, of which at least 20,000 are National Guard and Reserve. An additional call-up is more likely if the administration falls short of its goal of persuading other countries to contribute a total of 10,000 to 15,000 troops for security duty in Iraq. The Pentagon needs to know soon whether it can count on them being there early in 2004. George Bush did not receive any offers of troops for Iraq during two days of meetings with foreign leaders at the United Nations this week, said a senior U.S. official, who added that the question of sending troops did not even come up during Bush's talks with the leaders of Pakistan and India. ** US Inquiry May Not Have WMD Proof*** An eagerly awaited US inquiry is expected to report finding no concrete proof Baghdad had the banned weapons used to justify the invasion of Iraq. A senior United States official, on condition of anonymity, said the report by weapons inspector David Kay is expected to report finding "documentary evidence" of Iraqi chemical and biological weapons programmes, but no proof of the arms themselves. The Kay report "generally will be about chemical and biological weapons and I think he's going to find evidence, documentary evidence, statements by Iraqi scientists and technicians, that they had chemical and biological weapons production programmes," the official said. **Warning*** "Whether they will find or disclose anything on the weapons themselves, I doubt," he added. US national security adviser Condoleezza Rice warned it was too soon to say what US and British arms inspectors scouring Iraq for evidence of weapons of mass destruction will say in a forthcoming report. "I think that it is premature for anybody to start saying what is or is not in that report," Rice said in a briefing to reporters. Former weapons inspector David Kay, who leads the 1,400-strong Iraq Survey Group, "is still in the process, with some people in the intelligence community, of developing that report," Rice said. Kay served as a United Nations nuclear inspector in Iraq in 1991. "My understanding is that it is a report that is very much a progress report and that doesn't rule anything out or anything in," Rice added. "I would not jump to any definitive conclusions about what's in that report, and I think anybody who's doing that probably doesn't really know" what's in it, she said. The CIA described the Kay report as an initial document that will "reach no firm conclusions." **PHOTO CAPTION*** U.S. soldier sitting atop a Bradley armoured vehicle is silhouetted against a mosque during a night raid on houses in Tikrit, about 110 miles northwest of Baghdad September 25, 2003.
