U.S. ambassador to the Zionist entity, Dan Shapiro, said that his country is coordinating moves on Iran's issue with "Israel" more than any other subject.
This statement came on the background of the announcement by Chief of Staff U.S. Army, Martin Dempsey, who declare that he does not know whether "Israel" will alert the U.S. in advance about any attack against Iran in the absence of an "Israeli" commitment to the United States of acting alone against Iran. 

Dempsey spoke several days ago that there is a disagreement between the United States and "Israel" about the best way to confront Iran, and the US Secretary of War Leon Panetta had failed, according to "Israeli" media, to obtain a clear commitment by the "Israeli" Prime Minister Benjamin Netanyahu and Defense Minister Ehud Barak to not act against Iranian nuclear facilities without coordination with the United States.
