Yeah, but their tunnels are even better this time. Meanwhile, 37,000 tons of concrete sits in a warehouse, about to expire. Like 95% of Gaza's problems, Hamas is the root, but like 95% of Gaza's problems, useful idiots in the west will blame Israel.
No matter who is to blame a total collapse of Gaza will have serious consequences. People will have to go somewhere - either Egypt, Israel or - if blocked by their neighbours - they will try to reach Europe. So this is another refugee time bomb waiting to happen.
