> for people who don't follow news. last year Iran strikes on Israel with IRBM (two times, 150 missiles each time) weren't particularly effective (either intercepted or falling in empty fields).

For clarification, those interception efforts last year required massive assistance from the US and Jordan, and required a hugely disproportionate and unsustainable investment of munitions to pull off. What we've seen in the last week is that Israeli air defenses are much more brittle than they want anyone to believe.
