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.
My emphasis was more on the fact that the widely-touted success of the Patriot during the Gulf War did not, it seem, hold up to further scrutiny after the fact.
In light of this, proclamations of similar success in modern times should still be treated with the same level of scrutiny.
