Israel, in response to Iran's missile attacks, may attack Iran’s military bases, intelligence facilities or command posts, but not its nuclear facilities, according to sources, reports The New York Times. The sources added, however, that Iran's key nuclear facilities could be targeted in the future in the event of a possible further escalation of tension by Tehran if it retaliates. But there are growing calls in Israel and the United States to use the moment to delay Iran's nuclear program for many years.
