Russia has not been able to improve AA capabilities to the point where it's "safe", for any definition of the word, neither has Israel. Israel and Gulf states often tout over 90% interception rate yet it's really at the mercy of Iran to not target their most vulnerable sites. If Iran was routinely targeting desalination plants and refineries it wouldn't matter if it was 99%: one hit is all it takes. Similarly Russia cannot keep Ukraine from targeting their oil infrastructure.
Air defenses need to be 100% to prevent physical, economic and moral damage. That is an impossibility.

Air defenses do not need to be 100% effective to be... effective.
Russia cannot keep Ukraine from targeting their oil infrastructure, yet here Russia is, still fighting on. Ukraine cannot prevent Russia from targeting their energy infrastructure or apartment buildings, yet here they are, still fighting on.
If we're talking about strategic/civil air defense, then you must figure out what's tolerable to your population (and how to increase and maintain that tolerance), and then figure out all the means to reduce the incoming attacks to below that tolerance. That must include the full spectrum of offensive, counter offensive, defensive, and informational options.

And what this site and you don't account for, is Iranian rather low missile accuracy.
If Israel was at the mercy of Iranian attacks, Iran could have simply struck Israeli airbases to the point they cannot be used, and then stop any Israeli attacks on its territory.
It's pretty obvious they don't have the capabilities of doing that
I don't see how drones don't make all conflicts into WW1. 100 Billion dollars buys about 3.3 million Shaheds assuming the manufacturing is not made more efficient. There are many questions on whether its possible to spend 100 billion dollars on Shaheds, or launch all of them. But this is more than enough to destroy any logistics and transportation infrastructure necessary for a ground invasion.
There are many many countries who can afford 100 billion dollars for stored military equipment that has a long shelf life. The US makes ~50k artillery shells a month at a cost of about 10k per shell.
