WASHINGTON – US Secretary of State Hillary Clinton leaves Sunday for an overseas tour to find ways to help the Libyan opposition oust a third Arab leader and maintain the momentum of democracy revolutions. The chief US diplomat is due first in Paris for face-to-face talks with Libya’s opposition before she travels to Tunisia and Egypt, where she will become the highest-level US official to visit since their presidents were toppled. In Paris on Monday, Clinton will also meet her counterparts from host France as well as Russia, Britain, Canada, Germany, Italy and Japan to discuss combat-torn Libya amid divisions over calls for foreign military intervention. Her visit comes as forces loyal to Colonel Moamer Kadhafi have recaptured some lost territory and as top US spy James Clapper has said Kadhafi’s regime will prevail in the long run despite US and international calls for him to go.
