So how does Hamas get food and water?

12. I am glad you recognize Hamas is primarily made up of Gazans

(though of course not all Gazans are Hamas) reading some description one would believe they are aliens that landed in one specific location.

Asymmetrical wars and insurgencies are some of the most difficult to fight and win against. One option is to pound the opponent, and typically the people they represent, over the head until they give up. I cannot recall a case where this was successful. This is what Israel is currently trying.

Another option is a genocidal campaign where they targets give up or are fully eliminated. There have been several successes with this tactic. The Balkan wars, campaigns against American Indians, several African wars all fit this model. They are slightly more successful but at a horrible moral and human cost.

The third option is "hearts and minds". It is often successful but take a long commitment with little visible gain initially. Usually the frustration of the drawn-out effort leads to a change of tactics to the first option, try to beat the opponent into submission. Viet Nam come to mind as an example.
