Nope
Both would have to fly through Iraq to engage each other.
Not happening
and we would ally with Israel, destroying Iran’s air fleet...
Game Over...
Especially since Israel has already struck Iraq recently right?
Game over indeed!
Actually, this war, whenever it happens, is Iran and her allies (Turkey, Russia, Libya and others) attacking Israel.
Israel doesn’t go out to attack them. They appear to be caught by surprise.
Hard to say when this happens but Iran and Russia are already operating in Syria. Some have said Turkey is there too (but I haven’t seen much about that - other than one reference to it).
