A targeting accuracy of 75% — by the lowest estimate — cannot have been merely obtained by overhead photography from satellites or reconnaissance aircraft, because few Hamas objectives were classic “high-contrast” targets such as bunkers or headquarters…

So how did Israel do it? The only possible explanation is that people in Gaza have been informing the Israelis exactly where Hamas fighters and leaders are hiding, and where weapons are stored. No doubt some informers are merely corrupt, paid agents earning a living. But others must choose to provide intelligence because they oppose Hamas, whose extremism inflicts poverty, suffering and now death on the civilian population for the sake of launching mostly ineffectual rockets into Israel. Hamas completely disregards the day-to-day welfare of all Gazans in order to pursue its millenarian vision of an Islamic Palestine.

Some in Gaza must also resent Iran’s role in instigating the barrage of rockets fired on Israel. And all must know that the longer-range rockets are supplied by Iran along with money for Hamas leaders, while ordinary Palestinians languish in poverty.
