It sounds a bit like the United States is giving its blessing to Israel to attack Iran's nuclear facilities.
In an interview with ABC's This Week, Vice President Biden said Israel is a sovereign nation that must do what's in its best interests.
Biden's remarks seem to be the latest to support the possibility of Israel taking military action against Iran. Previously Egypt looked the other way as an Israeli submarine entered the Suez Canal, a signal to Iran that Israel is prepared to take the shortest route possible to the Persian Gulf if necessary. And Saudi Arabia tacitedly approved Israeli air force fly overs if an attack is launched.
