Well we have always known that Hamas gets their cut of all the tunnel smuggling. Like the mob during prohibition in the 1920's, they had the protection rackets and a cut of all the booze sold in the U.S.
So the blockade by Israel has been a boon to Hamas, they get their cut of everything smuggled, they protect the tunnel smuggles...for a price...or get their tunnels busted by the Egyptians.
But now we learn one new wrinkle Prime Minister Ismail Haniyeh owns at least one of the tunnels himself. It explains, even further why Hamas was so upset, when Israel lifted some of the restrictions about month or two ago. The smuggles were upset because the Egyptian goods TV's, Refrigerators, washing machines etc., were all having to be sold at a loss. Because the Palestinians in Gaza wanted the Israeli goods. Why? Because they were cheaper and better quality, than the Egyptian products.
So Hamas is just as corrupt as Fatah, they just pretend to be different. Their rejection, terrorist philosophy is just their scam, the Hamas way of keeping control of all the Gaza economy. So Hamas can get their cut of the action, and even their guy living in Syria, living like a king, owns a tunnel, all his own. Haniyeh is no different than Al Capone. Just a two bit thug who uses murder to enforce his will.
