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). On the other side Israel attempt on taking our Iranian AD was success.
It led Iran to make 2 decisions
- Accelerate production of IRBM in order to have 10000 in stock and to build 1000 launchers in order to execute massive launches that will not possible to defend against
- Apparently the did decide to mate their IRBM with nukes as recently there was meeting between whoever managed iranian missiles problem and heads of nuclear project (there is economist article about it).
This comes against backdrop of hamas and hezbollah been wiped. especially hezbollah which was supposed to be strike force against israel with estimated 100k-200k missiles and rockets.
PS. to those who write that jordan/usa intercepted most/a lot. they (together with saudi arabia, uk and france intercepted drones and cruise missiles. out of all IRBM only 6 were intercepted with SM3 missiles from USA ship)
