Netanyahu is focused on keeping himself out of jail and annexing the West Bank. He has no interest in Gaza other than it not present a terrorist threat to Israel. He may think that he can expel Gazans but reality will hit him soon enough: not only that they don’t want to leave but that there is no place for them to go. No other country will take them: Egypt doesn’t want offshoots of the Muslim Brotherhood, and the other Arab countries have learned from the 1970 experience of Jordan that letting Palestinians into their country led to an attempted takeover. So Netanyahu will have to come to terms with the continued presence of a couple of million thoroughly radicalized Palestinians in the Gaza strip.
Of course Netanyahu will be out of office and in permanent political exile within months, and hopefully the world and the new Israeli government will find a way for Gaza and Israel to at least leave each other alone, if not to live in peace and harmony.
