They do this because they use the Palestinian people, with the Palestinian people’s blessing, to be used as human shields
The “with their blessing” part is the only part I’d quibble with. And then I’d only want to add the context that Hamas was elected as the governing party in 2006 with a plurality, not a majority. They’ve since cancelled all future elections. So the Palestinians can’t rid themselves of Hamas if they wanted to. (At least not via democratic means.)
They could protest, but I think we all know how Hamas would react to Palestinians protesting against them and refusing to obey them.
