Why does Hamas deliberately flaunt the horrors it perpetrates? To demonstrate Israel’s lack of preparation and Hamas’s own military prowess? To spread terror? To disorient, to humiliate, to foster a sense of paralysis and powerlessness? To say: look, we can get you when and how we want? Or perhaps to say: yes, we are the beasts you say we are, come and avenge yourselves, come and get us in Gaza?
