Israel is using Palestinians as human shield. How do you expect Hamas to not be in civilians area in a highly populated 365 square kilometers area? Do you expect Hamas to kill themselves or to let Israel occupy land with no resistance at all? By resistance, I don't mean things like 7 of October but something like attacking military target

They used the population of the Gazastrip as human shields, building there bases in the City sometimes near hospitals. Using human shields is a war crime.

Correction: Israel claims they used (and still use) human shields. Those claims have not been proven in any way. You'll say they build their military bases and headquarters in cities, but literally every military in the world does that.

Hamas doesn't want a two state solution,

Look up the 2008 and 2012 ceasefires. Hamas isn't fundamentally opposed to a two-state solution. It's not their preferred result, but they've taken part in serious peace deals more than once only for Israel to destroy the whole thing.
