He explained, in a statement to Israeli Radio station, “we took a calculate risk yesterday – even Hamas understood that this was a cell gearing to carry out a terror attack."
"The reality today is different than it was three years ago, Gaza is relatively calmer today. The other side reacts (to strikes), but in a measured, calculated way. If the cracks noted in the lull widen we are ready to launch another operation, different and more diverse," he added
"The decision really is in the other side's hands. If they don’t stop the rocket fire and prevent “terror cells” from leaving to Egypt so to cross into Israel, we'll launch a Gaza operation – and it will be a painful one," he continued
As for Hamas' tactics against Israel, Hermoni said that "the tunnels allow ‘terrorists’ to reach us faster. They're digging tunnels on a daily basis, but we are employing intelligence to locate them. They're also getting ready for more abduction attempts."
