I'm sure the men and women fighting to save this cultural treasures are well aware if the tools available to them and are conducting the heart-rending job of balancing the damage being done by the flames, the damage that will be done by the various means to try and fight it, and the need to save as much as possible. I'm equally confident Little Donnie is incapable of understanding that. Perhaps his babysitters could get him a model cathedral and some plastic aircraft to play with as a distraction, before he says something even more unfortunate?
