You overestimate the power of conventional ballistic missiles and underestimate the power of merely owning nuclear weapons. In World War Two, Germany suffered more explosive power than what ever Iran has, and they were no where close to extinction, and that was when the Allies had shared borders and air superiority over Germany, you think you are going to wipe out cities with maybe at most a few kilotons worth of conventional weapons, and that's not even considering their kilometers long CEPs, the fact that the majority of them won't even reach Israel, and that most of the ones that will reach Israel will be intercepted?
Didn't you say Iran need to up its budget? You were so worried, you said "it's time Iran starts taking precautionary defensive measured", as if it's gonna loose otherwise, but later on you claim everything is fine and Iran has all in its hands, and that Iran's current arsenal is enough for an easy victory.
Not enough to get Israel anywhere near destruction
Most of your missiles will be located in Western Iran, because in order to reach Israel they need to be as close to it as possible, they simply wouldn't reach Israel otherwise.At this point I wouldn't be surprised if we were to use your neighbors airfields for our jets, the enemy of our enemy is our friend, even if we have our past experiences.
Remember when a Shahab 3 missile base suddenly blew up in 2011, along with Gen. Hassan Tehrani Moghaddam, the head of Irans missile program, and dozens of more Iranians? I wonder what caused it. Must have been the wind.
Now imagine this happening again, and again, and again. Because that's exactly what's going to happen.
And that's just the Mossad, what are you going to do when Sayeret Matkal and Shaldag units will sabotage your army? You wouldn't even know they were there until the damage is already done.
Chemical weapons or not, you launch ballistic missiles at us, chances are you're going to be microwaved.
How well your government will manage when Teheran along with all of your major cities are suddenly inhospitable to anything but lizards and cockroaches?
Chemical and Biological weapons aren't enough to destroy a nation.
Besides, every citizen in Israel has access to a bunker most of them are fortified in a way that unless a Scud will literally land on it, everyone inside will be intact and well.
