Sorry, i didnt followed the thread so dont know what is really discussed.
About the balance of power
Well Israel could blow main iranian cities and strategical sites overnight but would have to go nuclear for that so a big no no. Furthermore it is not even sure that surface bursts would be enough to deal with hardened underground facilities like Fordo/Natanz.
What both can do is lobb each other conventional ordnance with limited effect
Israel alone doesnt have the means for a sustained long range air campaign except if somebody accepts its planes closer on its soil (KSA?, Irak?, politicaly dangerous, dont see it done). So it can operate F15 long range flight but is limited by refueling and rearming capacities. It can hit hard, but not really threaten the regime as a whole.
Iran has also long range means MRBMs like Sahab3 but limited in numbers (40 to 50 launchers IIRC) and subject to interception by Iron Dome. However, it can push its Hezbollah proxie to act which means hundred of short range systems activated, mostly against northern israeli settlements. A few of them can reach deeper but they are not the majority.
In other words, tacticaly each other can do harm to the oposite side but has no means to defeat the other country armed forces.
The result of a war between both would then depend of political factors, something that is not really predictable (failure to stop a sustained operation on one side or the other for example can eventualy topple a gov ... or trigger a nationalist reaction hardening the conflict. Hard to tell there)
