Sure, but Iran did sponsor proxies that did attack Israel. And whether something is direct war or proxy war feels more like meaningless semantics imo.
Historically speaking I think it's clear Iran has been the aggressor in this specific conflict.
Not that I think Israel took smart actions, but that's a different matter.
Korea was a proxy war between the US and China - which is very different from a direct war between those two countries, wouldn’t you say?
