U.S. President George W. Bush has told a roomful of top Pentagon brass his administration would never stop looking for ways to harm the United States. The latest installment of misspeak from a president long known for his malapropisms came during a signing ceremony for a new 417 billion US dollar defence appropriations bill that includes 25 billion in emergency funding for operations in Iraq and Afghanistan. **"Our enemies are innovative and resourceful, and so are we. They never stop thinking about new ways to harm our country and our people, and neither do we," Bush said on Thursday.*** The Republican incumbent, who is in a tight race for reelection against Democrat John Kerry, a decorated Vietnam veteran, used the 11-minute presentation to underscore his commitment to U.S. troops. On hand for the ceremony were Defence Secretary Donald Rumsfeld, deputy Defence Secretary Paul Wolfowitz and Gen. Richard Myers, chairman of the Joint Chiefs of Staff. **PHOTO CAPTION*** U.S. President George W. Bush.
