"But there are no reasons other than collective punishment for the response they have chosen for the kidnapping of two of their soldiers. "


Oh, really? You think that the roads would not be used to transport troops, supplies, and the Israeli kidnap victims? IF there was collective punishment, there would be attacks on UNRELATED civilian infrastructure- which I do not see as the case- Transportation and power systems are legitimate military targets, to deny the enemy suppiles, movement, and immpact the ability to fight.
