Got any statistics? You know, actual facts.
Oh wait, I do.
"
UNOSAT identified 60,368 destroyed structures, 20,050 severely damaged structures, 56,292 moderately damaged structures, and 34,102 possibly damaged structures for a total of 170,812 structures. These correspond to around 69% of the total structures in the Gaza Strip."
Which leaves us with:
24% destroyed
8% severely damaged
23% moderately damaged
14% may or may not be damaged; damage minimal
31% intact
Significant damage, certainly. But also significant tunnel infrastructure, so it tracks.
