>>507589374 (OP)Israel strikes are mostly air-launched and can get (relatively) close to their target to enhance their accuracy. The weapons they are using have very effective modern guidance systems
Iran's strikes are launched from within Iran, and without access to the technology for modern guidance (due to sanctions) they must rely on volume of fire to indiscriminately blanket the area around a target.
On top of that, Israel's air defense system works by predicting the trajectory of incoming missiles and prioritizing targets. Missiles that will actually impact strategically significant sites are 1st priority, critical civilian infrastructure is 2nd priority, nonessential civilian infrastructure is 3rd priority, and missiles that aren't projected to hit anything at all are ignored. That so far the only successful strikes have been on 3rd priority targets demonstrates that Israel can't completely intercept the whole volume of an Iranian missile barrage, but that these barrages can't generate enough volume or enough accuracy to get strikes through on 2nd or 1st priority targets.
This defensive system is relatively effective because all of Israel's regional adversaries lack precision weapons, so a considerable volume of any strike can always be safely ignored or deprioritized as they miss important targets. Damage to highrises and houses is of course tragic but does nothing to deteriorate Israel's military capability, and so only begets more strikes against the launchers that will gradually degrade their ability to saturate the defensive system.
