With supplies like concrete, with steel, unfortunately you could have a situation where that is diverted by Hamas, and instead of helping people to rebuild houses, they'll be building underground bunkers for their own military machine.
Desgraciadamente con suministros tales como cemento y acero, puede darse el caso que sean desviados a Hamas, y en lugar de ayudar a los ciudadanos a reconstruir sus casas, se usen para construir búnkeres subterráneos con fines militares.
