According to the news of the American press, which is based on US and Israeli sources, the proposal was conveyed during the visit of US Secretary of Defense Lloyd Austin, Chief of Staff General Mark Milley and US Central Command (CENTCOM) Commander General Michael Erik Kurilla to Israel.
Israel, on the other hand, showed an "indifferent" approach to the proposal, fearing that if the US objects to a possible attack on Iran, it will tie their hands in Israel's unilateral military actions.
An unnamed US official stressed that the proposal to carry out "joint military planning" against Iran "is not a joint attack plan against Iran's nuclear program".
Another US source claimed that the plan was not intended to "tie hands" on Israel.
An unnamed Israeli official, on the other hand, pointed out that while they did not reject the idea (offer), they were waiting for an explanation as to what this would mean in practice and whether it would evolve into joint operations.
Pentagon spokesman Lieutenant Colonel Phillip Ventura told Axios that Defense Department leaders "have repeatedly made public statements of interest in expanding military cooperation with the Israel Defense Forces, including increasing joint participation in military training exercises to develop and promote interoperability."
