Ofcourse it would be naive to think Hamas doesn't have some support in Gaza because they are not just some small little group but the governing body there.
But does it mean that even those who supported them for certain aspects prior to the war means they also supported them in carrying out the actions of October 7th?
If suggesting that then it could make the dangerous implication that the civilians deaths in Gaza are somewhat justified. Not that I am saying that you are saying that but that's how it can be read in to
I read on BBC verify that although different factions took part in drills they don't believe it was until the day of the attack that Hamas told even the other groups about it.
And in regards to the hostage who escaped and was taken back we don't really know the circumstances around it and there could be many possibilities
It seems that the PIJ are much worse and if they had captured him then he may not have been released
It is a sad state of affairs and does indicate how much work is needed
(Just my own thoughts)
