The IDF view COIN as being a normal part of what they do everyday. The foundations of the IDF are in both insurgency and counter-insurgency. In 1948 the IDF had 8 tanks and 3 of those they stole from the British! They wanted to steal more but had no one who could drive tanks!

It was far harder for them to learn Combined Arms Armoured manoeuvre, (and still is) than it was to master guerilla or counter guerilla warfare. The IDF is founded entirely pragmatism. Do what works.

However this pragmatism has to be balanced against acceptable forms of conduct, which is further challenged by facing foes who tend to operate normal moral parameters. -EG: how do you conduct ATGM counter-fire into a village full of civilians?

...and do not be lulled into the simplistic idea that somehow the IDF performance in the August War was because of a lack or operational or tactical skill as a product of over investment in COIN doctrine. The failure of the IDF was purely to do with Effects Based Operations, driven by airpower doctrine.
