CarolC--If your point is that that settler should receive more punishment, agreed.
If your post is a rebuttal to beardedbruce's, a justification of IJ's breaking the Gaza truce, you're way off base. The student's attack took place nearly two weeks before the Truce went into (non)effect.
I also note that before the Gaza truce was breached, Israel had already loosened the blockade, allowing supplies to enter Gaza. No good deed goes unpunished, as is said.
