A foreign country loaned Israel MIG 29 fighter jets for practice purposes. Iran operates MIG fighter jets. Israel equipped its F-16's with maximum payload for the exercises.
In a related story from the Jerusalem Post, outgoing IAEA Chief Mohamed ElBaradei said Israel would be "utterly insane" to attack Iran:
"That would turn the region into one great fireball, and the Iranians would immediately begin building the bomb - with the support of the entire Islamic world."
Israel has a habit of making war with direct support from the United State. We'll find out how much has changed. Their record on settlements remains clear.
