“But that wouldn’t make sense because the Gazans don’t have billions of dollars.”
Actually the Gazans would have an estimated $4.5 billion from the gas fields just offshore from Gaza but Netanyahu is intent on keeping this for Israel proper. If you don’t think that this was an important part of the calculations for going to war then you are hopelessly naive.

Yes, it is certainly possible that Netanyahu wants the offshore gas for Israel. It is also possible that he wants to ensure Hamas doesn't get the billions that would come from access to that natural gas.
BTW, if you think citation of a leftist publication is valid support for your claim then you are hopelessly naive, intentionally ignorant, or both.
