Your barrel bombs and mortars and air strikes have allowed the militia in Aleppo to encircle tens of thousands of civilians in your ever-tightening noose. It is your noose. Three member states of the U.N. contributing to a noose around civilians. It should shame you. Instead, by all appearances, it is emboldening you. You are plotting your next assault. Are you truly incapable of shame? Is there literally nothing that can shame you? Is there no act of barbarism against civilians, no execution of a child that gets under your skin, that just creeps you out a little bit? Is there nothing you will not lie about or justify?
