I think what they are cheering about is the secondary explosions they see once a bomb hits a munitions storage site. The blast indicates a very successful hit. The leaflets and phone calls to homes that are about to be hit tell the residents to go to Gaza city which is relatively safe. Why no outcry about the indiscriminate rocket fire aimed at Israeli targets. Hamas is trying to kill as many civilians in Israel as possible. It’s not happening only because of Iron Dome anti-missiles and bomb shelters. Every tunnel going into Israel required 700 tons of concrete (13 destroyed so far). That’s 9,100 tons of concrete that could have built schools, hospitals, shelters, etc. But no, Muslim civilians deaths is what Hamas want as popaganda to show to the world how evil Israel is while they used their own civilians as human shields.
