How has it been a bad week for the "But Hamas started everything" point of view? However much stuff you post about wartime atrocities you can never change the fact that Hamas did start this war. There was an uneasy truce before October 7th so I don't see how you can really fail to see that Hamas did start this war.
Equally, Israel do have a right to defend themselves, I would have thought that is unarguable.
Every country has a right to defend itself from massacres though I do agree the IDF have gone too far in their retaliation.
The fact that Israel is winning the war that Hamas started is because of their superior army, defence system, weapons etc. If Hamas had the capability they would do the same or worse to Israel. That is quite clear from what they have already said and done. Hamas insist on hiding out & storing weapons under public buildings like hospitals with the inevitable result that more civilians are killed than if they used different tactics.
