At this time, it is up to Israel whether or not war occurs between the US and Iran. Israel very much wants this war as a means of putting Iran and Syria into chaos, thus leaving Hezbollah isolated and unsupplied. Then Israel can succeed in occupying southern Lebanon.
The American neoconservatives want Iran in chaos, because then the chaos can be exported into the Muslim regions of the Russian Federation with the purpose of causing sufficient internal turmoil to remove Russia as a constraint on US unilateralism.
