Probably overblown (has tunnel-building been so effectively blocked, that they can't get in concrete?), but:
COHEN: Well, Gaza looks at this point, eight months after the final ceasefire that ended Operation Protective Edge last year, Gaza looks about the same as it did on the day of the ceasefire. There has been a very small amount of rebuilding. One very sobering statistic is that not a single house that was completely destroyed has been rebuilt. A lot of the reconstruction efforts have, promises of $5.4 billion to rebuild Gaza, have not been fulfilled. And this is because Israel, Egypt, and the Palestinian authority have colluded to prevent reconstruction.
And so additionally as you mentioned, the economy is devastated, and it's an intentional policy of de-development, we could call it, where all sectors of the economy are under siege, and it's really horrendous on the ground.
