That "source" dives straight into debunked Israeli propaganda. From repeatedly claiming Hamas took control of Gaza by force to repeating the debunked claim about beheaded babies. Then it ignores anything written after the year 2000.
It buries the fact that Hamas won election more than ten paragraphs down. As if to provide the author a defense of having mentioned it.
They also completely neglect to mention Hamas won that election on a moderate platform and was immediately attacked by Israel, physically and politically, for doing so. When the result of a moderate, anti-corruption, party winning is an immediate de facto declaration of war, I don't see how anyone can objectively claim Hamas as the oppressor.
Now to the current situation. Israel should be dissolved. The commission of a genocide is beyond the rights of any state and is a clear sign they cannot be trusted partners in peace. The only right answer is a UN transition government to a representative democracy that gives everyone rights to vote and bars the military from acting inside the borders of the successor state.
