They could stop the current stage of the war, sure. They couldn't achieve peace though - basically stopping the operation would mean reverting to pre Oct. 2023 state with Israel trying to improve their security (aka "blockade") so that it doesn't happen again. Given the recent advances in military practice I would imagine that would involve lots of drones flying over Gaza 24/7 and I can already hear what international organizations are saying about that.
Hamas on the other hand has the keys for the permanent peace. Not implying that the way current operation is waged is justified though.
Israel can become one state with democracy for all its residents. That's the real answer.

What will they say? (And would they be wrong?) Imprisoning Palestinian refugees is definitely a human rights violation.

Not sure why everyone says Israel (the state with all the power in this relationship) is powerless. What do you propose Hamas do to ensure permanent peace?
