Iran has fired 450+ ballistic missiles. Roughly 50 or so impacts have been recorded in Israel. That’s an interception rate of roughly 90% or slightly under.
Israeli AD has performed as well as can be expected, and that’s within the acceptable RISK Israel is willing to take when they’ve destroyed the Iranian military hierarchy, destroyed a huge amount of its ballistic missile program, and done significant damage to its nuclear sites. And they’re not anywhere near done. Israel has gained strategic effects on Iran, Iran has not. Therefore, Israel is currently winning the war.
If you don’t understand this, that’s your problem not mine.
