Remember SDI? That Reagan `smart pebbles` concept that was used to bring the Russians to Reykjavik? The Dims pooh-pooed it then as not workable.
Roll forward 30 years and a world away and you have Israel implementing their own version of SDI. One to deal with the Hamas Gaza threat a second intermediate range to deal with Iran. They may not have a fool proof system but dealing with 80% ain’t bad.
I also note that the systems in the video all appear to be portable. At least the radar array certainly is. Think Iron Dome deployed in Saudi Arabia and the both countries might be capable of hitting the rockets in boost phase.
