US President George Bush announced that the US is stepping up discussions with key European and Asian allies about the overhaul of US global military deployments. US Secretary of State Colin Powell and Defence Secretary Donald Rumsfeld will provide more details of Washington's plans at NATO ministerial meetings in early December, Bush said in a statement released by the White House. A senior administration official said the president was not accelerating the process of revamping deployments, just moving ahead with planned consultations with key allies on where best to position US forces.
