Not only are rockets are not missiles, but why are you bringing up the Iron Dome when the subject of the article was the Patriot?
Why are your bringing up data from 1991 in 2023? The Patriot of today is a several generations newer than 1991.
I mention Iron Dome to highlight that technology has moved on since 1991, and we can see surface to air missile systems successfully intercepting daily.
Israel has successfully tested, used, and currently deploys Patriot missile batteries, so you might infer that Israel knows that the Patriots work.
