You are wrong about that. They are using 500, 1000, 1500 & 3000 kg bombs, create a lot of damage, kill all people in and nearby a house, but no building is pulverized. Look, if IDF would use a 500 KTN bomb, that would equal to 500,000 Tons of TNT. That explains your claim about the "1%".

Yeah, occasionally, but the biggest they have on a rocket is 700 kg, and the artillery shells are tiny. They're not dropping large gravity bombs anywhere near air defenses.
