Israel is preparing for a ground assault upon Hamas in Gaza, which will not be easy, given the use that will be made of vast underground tunnel networks, which are more sophisticated than those used to great effect by the Vietcong against the US forces in the Vietnam War. Hamas has had much more time to construct an underground world, literally, complete with hospitals, and massive quantities of supplies, as it prepared for this battle over years.
And, while the IDF can destroy Hamas eventually, war on another front with Hezbollah is almost certain and the IDF have evacuated more towns and villages near the northern border in anticipation of a second war. This war will be even more dangerous as Hezbollah is far better equipped, thanks to Iran, with more military tech than the rag bag armies of Hamas, with at least 150,000 missiles that can be fired into Israel. The weapons from Iran get transported to Syria, and the IDF has bombed the airports at Damascus and Aleppo three times recently to slow up the supply. Thus, Syria is involved now, inevitably. And in turn Iran will also engage at some point. It is generally thought that the US will actively engage to prevent the mass missile attacks that Hezbollah will launch. Thus, it seems the Israel- Hamas war will morph into an all-out Middle East War.
