Israel, madam.
And so what, yes the Egyptians closed the border, does that mean you consider it fine for Israel to do those things, and they can escape being labelled of "barbaric war criminals", because... why? Because Egypt?
It's like an abusive father beating his kids, and when the neighbor doesn't want to have the burden of taking care of the kids for the foreseeable future (because the police/government clearly prefers to pretend "everything is fine"), you say "Well, it's the neighbor's fault those kids are getting beat up!".
