All politicians leaders of Palestinian people have eventually refused a 2-states solution. Israël does recognize a few groups as valid diplomatic partners but not Hamas, who is in charge right now. And yes that will lead to a lot of harsh suffering for Palestinian people, partly/mostly because of the way Hamas has handled things.
Note that I'm not downplaying what Israël has done in the region so far, and I'm not giving them excuses ; they do what they think is best for their security, rightfully or wrongfully, given that their neighbour is lead by a terrorist group. I'm not sure how I would react as a civilian or a leader of either country and I would certainly not advise anything to anyone. But clearly Hamas is the agressor just like Russia is the agressor in Ukraine (and both have intention of destroying not only the state but also the people).
