In this case the delivery was very accurate but there was no assurance that the correct targets were holding the device and that no innocents nearby would be harmed.
Any one of those holding the device could have been an innocent bystander, a storekeeper, a doctor or an EMT helping someone with an unrelated medical condition.
Any one of those holding the device, guilty or not, could have been holding a child or filling a car with gasoline.
Yep, shit happens.
If you weigh that possibility over the value of the targets killed or injured, it is well worth the risk.
People terrorists associate with are not friends of Israel. "Innocent" becomes a question of degree.
Are "innocent" people feeding terrorists? Providing them with shelter? Comforting them?
Very blurred line between terrorists and collaborating "innocents."
Who cares. Terrorists go boom. Go cry for your Allah elsewhere...
Um, I'm sure Hamas was very careful in who they blew up. Didn't matter to them whether they murdered a baby, a pregnant woman, a grandmother, a son, or a beautiful young woman. Hamas-niks deserve, even their innocents, all the worst. You're known by the company you keep.
