The countries who pledged vast sums to rebuild the Gaza Strip in Cairo Sunday will have made worthless donations if the people of the Gaza Strip return to terror, Transportation Minister Israel Katz said Sunday.Katz, who is one of the ministers closest to Prime Minister Binyamin Netanyahu, issued the warning at a gathering of some 2000 Likud activists outside his Succa on his ranch on the Moshav Kfar Ahim in the northern Negev."The Gazans must decide what they want to be Singapore or Darfur [which rhymes in Hebrew]," Katz said. "They can pick between economic recovery and war and destruction. If they choose terror, the world should not waste its money. If one missile will be fired, everything will go down the drain."
