Iranian spokesmen have begun to threaten Israel not only with a massive response to any potential attack, but also with a preemptive strike. And a drone was recently sent over southern Israel, most likely launched from Lebanon, either by Hezbollah, acting in Iran's service, or by forces of the Iranian regime itself.

TEL AVIV – A drone recently penetrated Israel’s airspace from the Mediterranean. It was allowed to fly for about half an hour over southern Israel before being shot down by the Israeli air force over a sparsely populated area. It is still not known who dispatched the drone and from where, but it is now assumed that it was launched from Lebanon, either by Hezbollah, acting in Iran's service, or by forces of the Iranian regime itself.
