The author BS'es when he suggests the IDF threw a lot of its resources into the battle. It used infantry mostly, the least effective means of destroying the terrorists. The idea was minimize civilian casualties, but they could not be avoided when the Islamic Jihadists intentionally fought behind/among them.
More BS is that the "heart of Jenin has been ripped out". Only a small section of Jenin, and as much from the thousands of explosives strung all over the camp by the Jihadists as from the IDF.
When you want to kill something, that is a good way to do it. How many of the homicide bombers came from Jenin?
