But then Hamas got into power with a plurality of the vote and have been constantly attacking Israel ever since.

Hamas has always been extreme in rhetoric, but the violence afaik began when Israel, the US and the PA attempted to coup them out of power.

There have been a few times in this war there has been ceasefires with hostages exchanged for prisoners. Hamas eventually stops releasing hostages and the conflict resumes.

So far every ceasefire was broken by Israel, because they were unwilling to enter the next phase of negotiations which was a precondition to the release of more hostages.

It doesn’t seem like Hamas wants sovereignty, they could have had that if they wanted it.

Like how Israel respects the sovereignty of the PA in the West Bank? Yeah right.
