As an aside here's something that's always bothered me...
Hamas has been using all of these tunnels to funnel arms and supplies through. Why...don't they get supplies to better protect their people? Make bunkers similar to what the Israelis have? I know they get food/medical supplies/and other shit but why the focus on the rockets? When it just kills civilians?
To me it just suggests Hamas seeks to benefit from the attacks on both ends. Provoking a response vastly more lethal invigorates their base via outrage/anger. And it allows them to play the victim.
