A large part of the gaza strip has already been levelled, and the residents are living off Israeli food aid, electricity etc. And the destruction is ongoing while Israel hunts down Hamas and tries to find the hostages. It is hard to tell what anyone else could threaten them with, as no-one wants to have them living off their welfare. They already know they will get more of the same until the hostages are returned. They have always chosen more of the same. There is nothing really left to be said. That's why Hamas, Israel, Trump and everyone else are not really saying anything. Everyone is just waiting for the people of Gaza to come to their senses. Don't hold your breath.
