It doesn't matter how much aid comes in from the United Nations or European countries and NGOs. Those bombed out buildings are so much more photogenic and pitiful.
The cement and other building supplies that Israel keeps letting in is used for the tunnels which are part of the terrorist infrastructure to destroy Israel, Gd forbid.
Hamas, ignoring its damaged buildings in Gaza, clearly has sufficient funds (supplied by Qatar and Turkey) to rebuild its attack tunnels and replenish its rocket arsenal — while it exports its terrorism to us on the West Bank, with the goal of toppling the Palestinian Authority.
