Former U.S. Defense Secretary Donald Rumsfield told Fox News that Israel is better off going at it alone against Iran.
While current Defense Secretary Leon Panetta attempted to stave off a strike on Iran's nuclear facilities during his visit to Israel last week, Rumsfeld said sanctions have been ineffective.
"The Prime Minister of Israel, Netanyahu, is probably correct," he said. "Sanctions tend not to work very well over a long period of time."
Rumsfield, who was secretary of defense during both the Ford and the second Bush administrations, expressed confidence in Israel's intellegence on Iran.
"I don't think that Israel has to destroy all of Iran's nuclear capability," he said. "Iran is a sophisticated country. They must have deeply buried sites. And I'm sure the Israelis know precisely what they currently have."
Rumsfeld also criticized the Obama administration for its pattern of leaking information to the press.
"If I were in the Israeli government, I don't think I would notify the United States government of any intent to do anything about Iran," he said.
"So my guess is, given the pattern of leaks out of the White House, that any prime minister of Israel would not call the United States and give clear intentions as to what they plan to do."
Despite President Barack Obama's continued solution of harsh sanctions, Panetta did assure both the prime minister and Defense Minister Ehud Barak that the United States would act when it is clear that military intervention is unavoidable.
