Hamas doesn't seem to be launching nearly as many missiles this time. Not nearly as much damage being witnessed in Israel, but still some.
Hamas isn’t involved in this conflict. It’s PIJ a separate group.
They are much smaller (1-3K members) and have a fraction of the rockets of Hamas. Mostly rudimentary ones that are easy for IRON Dome to intercept. While they are supported by Iran, it is hard to smuggle in quality weapons into Gaza when Israel has full inspection rights of every shipment.
