In April, Iran launched around 170 drones, over 30 cruise missiles, and more than 120 ballistic missiles towards Israel. Most were shot down while a few landed near Israeli military facilities.
CNN cites a senior White House correspondent saying the attack looks to be a similar size. A separate report from Reuters suggests the attack will be “at least as big” as the one in April.
The whole thing was a face-saving exercise from Iran then but it seems like Netanhayu is emboldened, so you never know what’s coming now.
