Iran tried the same back when they were certain the U.S would attack powerplants and bridges after one bridge attack. They publicly placed children and handicapped on the bridge and filmed it. Adults around the powerplant. It's an Islamic wartime strategy. What the U.S did instead was attacking Kharg Island, effectively cutting them off from 90% of their oil access.
Anyway, back to Hamas:
Ah yes, it's still disputed who broke it. I don't trust Israel, but I trust Islamic terror organizations even less since they hide behind- and sacrifice civilians. The most evil bastards in existence, and Hamas isn't special, they just follow the usual script. Plus calling their soldiers 'people' is rich.
