U.S. Envoys Head Out on a Mission to Rally Iran's Neighbors.

With tensions over Iran's nuclear ambitions hitting new levels, the United States is mounting a diplomatic full-court press in the Middle East, sending four top diplomats, including Secretary of State Hillary Rodham Clinton, to confer with Arab and Israeli leaders. The envoys' visits to Israel, Lebanon, Syria, Jordan, Egypt, Saudi Arabia and Qatar were planned separately in recent weeks, but they now have a common purpose, administration officials said: to reassure Iran's neighbors that the United States will stand firm against Tehran, and to enlist other countries in a global effort to put pressure on the Iranian authorities.
