“each usually carried out by two groups of three aircraft. A typical mission dropped 168 tons of ordnance, pounding an area 1.5 by 0.5 miles (2.41 by 0.80 km)”
Roughly a square mile: 168 tons, per Vietnam war an B-52 ARCLIGHT

GAZA is 141 square miles, so this times 168 tons of TNT gets you to 23.5 kilotons of TNT … and this would be horrendous.
Now imagine doing 3 times that amount.
