Israel's defense minister Ehud Barak said Thursday that differences remain with the U.S. over Iran's nuclear program, despite efforts by Israel and the U.S. to come to an agreement on the issue.
He said "the clock is ticking at a different pace" for the U.S. and Israel. Barak spoke after meeting the U.S. Vice Chairman of the Joint Chiefs of Staff, Adm. James A. Winnefeld.
Israel and the U.S. both believe that Iran is trying to develop nuclear weapons. Israel views a nuclear-armed Iran as an existential threat, citing Iranian calls for Israel's destruction, the country's development of missiles capable of striking the Jewish state, and Tehran's support for Islamic militant groups hostile to Israel, such as Hamas and Hizbullah.
