Subject: Re: WHY does Israel have to wait for
As I recall, it was reported that the Iranian ships activated their targeting systems against our aircraft. We then made short work of them. They didn't fire, and we didn't give them the chance to. Activating targeting radar was enough.

Yup. If you've turned on your tracking radar, that's akin to pointing a gun at somebody and cocking the trigger. You take the shot in that case.
