Yet,, we still there.
If Iran enters a war with Israel, yes
Air route is too easy to intercept, you can't make a plane disappear.....sea route again, NATO would block both Red Sea and Gibraltar choke point, you can't ship anything to Lebanon if you cannot pass thru either choke point. And how much stuff you can carry thru ground route and how long does it take. It's like asking Russia to bring in their war material to support the war in Ukraine over land from Siberia.....
Basic manufacturing, probably, not anything complex, and you can't win a war without a Ground component, Russian SRBM wouldn't work in Ukraine, hell, RuAF didn't work in Ukraine either and you are talking about Israel, which are 100 times better defended from the air. You will need heavies to go in and take Israel out, otherwise it's hard to punch thru the Iron dome, and even if you can, each SRBM have a payload no more than a 2000lb bombs, it's not going to make much difference. And it would be extremely non-cost effective to lob missile into Israel.
