Hamas members are entrenched in civilian buildings and tunnels, and they are well equipped to attack tanks, and they wouldn't hesitate to blow themselves up
it would be suicide for the IDF to do a slow invasion of Gaza, the IDF doesn't have such a big army, and this would drag along and allow hamas leaders to run away, and would allow hamas to regroup.
also, the more time passes, the more it gives hezbollah and other actors to attack.
maybe the US army would have enough foot soldiers to invade by foot and check every street, but again, with human shields and guerilla tactics, it's not sure it would be that much better, because US militaries are probably not really trained enough to deal with such a big hornet's nest that is gaza.
