So after few hours since iran used BM against Israel what did I learn... Ballistic Missiles suck when it comes to hitting target and doing damage. They tried going after Mossad HQ and it is still standing. You know what is extremely more effective in getting results... aircraft carrying 1000, 2000, 3000 or 5000lbs JDAM or bunker buster. They went after airbases and they weren't even knocked out of operations now it is Israel's turn and we're going to see the difference.
Conventional BM don't cut it.
That sort of generalization is simplistic and flawed.
The effectiveness of any sort of strike system whether it's ballistic missiles or manned strike aircraft entirely depends on the advancement of your munitions, your supporting ISR, EW, BDA, and the advancement and scale of defenses that the adversary can put up.
